1. Bank Management System Project In C++

A bank management system in C++ is a beginner's project that is great for students. It is made such that it helps users manage their bank accounts. It allows users to create an account, deposit and withdraw money, and check their account details. This project suits students who want to learn basic programming concepts and Object-Oriented Programming (OOPs) in C++ and test their knowledge. It’s a great learning example for handling user input, managing account transactions, and using C++ classes and objects. 

The main features of the banking application include:

1. Account Creation – Users can open a new bank account by providing their name, account number, and an initial deposit.

2. Deposit Money – Users can add money to their account.

3. Withdraw Money – Users can withdraw money if they have enough balance.

4. Check Account Details – Users can view their account number, holder name, and balance.

Process Required 

To build this bank management system in C++, you need to understand several programming concepts:

1. Library Functions: We use standard C++ libraries like <iostream> for input-output operations and <vector> to store multiple bank accounts.

2. Memory Management: The data is stored in runtime memory. Therefore, efficient memory handling is required. We use vectors instead of raw arrays for dynamic data storage.

3. Object-Oriented Programming (OOPS) – The project is built using classes and objects. A class BankAccount stores account details and functions like deposit(), withdraw(), and displayAccount().

4. Control Structures: The program uses loops while and for, decision-making statements (if-else), and functions for better code organisation.

5. Error Handling: The project includes basic checks like preventing negative deposits, ensuring sufficient balance for withdrawals, and validating account numbers.

How the Code Works

The bank management system in C++ is designed using Object-Oriented Programming (OOP) principles. Users in this program can create and manage bank accounts through a menu-type interface. Below is a step-by-step breakdown of how the code works:

1. Class Definition (BankAccount)

The BankAccount class is used to store account details, including:

• Account holder’s name
• Unique account number
• Balance in the account

It contains functions like:

• deposit(amount): Adds money to the balance.
• withdraw(amount): Deducts money if the balance is sufficient.
• displayAccount(): Shows account details.

2. Account Creation

• The user is prompted to enter their name, account number, and an initial deposit.
• A new object of BankAccount is created and stored in a list (vector/array).
• This allows multiple users to store their accounts in the system.

3. Depositing and Withdrawing Money

• The user enters their account number to perform transactions.
• The system searches for the account in the list.

If the account exists:

• Deposit: The balance increases by the entered amount.
• Withdrawal: The system checks if the balance is sufficient. If yes, money is deducted; if not, an error is shown.
• If the account is not found, an error message is displayed.

4. Displaying Account Details

• The user enters an account number, and the system retrieves and displays the corresponding account holder’s name and balance.

5. Menu-Driven User Interaction

• The program runs inside a loop until the user chooses Exit.
• A switch-case structure processes and directs user inputs to the appropriate function (Create, Deposit, Withdraw, Display, Exit).

Output

In this example, we’ll see how a person can create their bank account, deposit money, then withdraw that money, and in the end, check the balance:

An intermediate-level project is a next-level challenge for students with foundational programming concepts, like object-oriented programming, data structures, and basic algorithms. It requires better problem-solving skills, such as managing larger data sets, implementing efficient code, and creating functional systems. These projects bridge the gap between beginner-level exercises and advanced, real-world applications. Now let’s look at a C++ project ideas intermediate for you to practice.

1. C++ Hotel Management Project 

The hotel management C++ project is an intermediate-level project. The idea is to automate the management of hotel bookings. It allows users to book rooms, display booked rooms, and check out customers. The system provides a robust solution for managing hotel operations and simulating real-world scenarios. 

Process and Concepts Involved

To build this project, several important concepts and tools are used:

1. Libraries and Functions

• #include <iostream>: Used for input and output operations.
• #include <vector>: A dynamic array that allows flexible room bookings and customer storage.
• #include <algorithm>: Functions like std::remove are used to manage and manipulate the data effectively.

2. Object-Oriented Programming (OOP)

• Classes and Objects: The project is structured around the Hotel and Customer classes. Therefore, it encapsulates relevant data and behaviours (methods).

3. Memory Management

• Dynamic Memory Allocation: By using vectors, the program manages memory well. It adjusts the size automatically as rooms are booked or checked out.

4. No Explicit Pointers: Basic memory management concepts are applied without requiring pointers. Hence, it is easier for students at this intermediate level.

5. Data Management

• Vectors: Used to store dynamic lists of customers and booked rooms. It makes the system adaptable to changes without worrying about fixed sizes.

6. Input/Output Operations: Students practice handling user input and displaying structured information, allowing real-time interaction with the system.

Algorithm 

1. Start: Display the main menu options:

• Book Room
• Display Booked Rooms
• Check Out
• Exit

2. Book Room 

Input: Ask for customer details:

• Name
• Room Number
• Phone Number

Check Availability:

• If the room is already booked (check if the room number is in the list of booked rooms):
• Display an error message "Room already booked."

If the room is available:

• Add customer details to the list of booked customers.
• Add the room number to the list of booked rooms.
• Display success message: "Room successfully booked."

3. Display Booked Rooms 

Check if No Rooms Are Booked:

• If the list of booked rooms is empty, display "No rooms are currently booked."

Display Booked Rooms:

• Iterate through the list of customers.
• For each customer, display their name, room number, and phone number.

4. Check Out 

Input: Ask for the customer's room number when checking out.

Find the Customer:

• Search the list of customers for the entered room number.

If the room is found:

• Remove the customer from the list of booked customers.
• Remove the room number from the list of booked rooms.
• Display success message: "Room successfully checked out."

If the room is not found:

• Display error message: "Room not found or already vacant."

5. Exit the Program 

• Display a message: "Exiting... Thank you!"
• Terminate the program.

        cout << "4. Exit\n";
        cout << "Enter Your Choice: ";
        cin >> choice;

        switch (choice) {
            case 1:
                hotel.bookRoom();
                break;
            case 2:
                hotel.displayCustomers();

                break;
            case 4:
                cout << "Exiting... Thank you!\n";
                return 0;
            default:
                cout << "Invalid choice! Please try again.\n";
        }
    }

    return 0;
}

How The Code Works 

The hotel management system in C++ simulates a basic hotel booking system. Here's a breakdown of how it works: 

1. User Interaction

The program starts by displaying a menu with options to:

• Book a room
• Display booked rooms
• Check out a customer
• Exit the program

2. Room Booking:

When the user chooses to book a room, the program:

• Takes input for the customer's name, room number, and phone number.
• Check if the room is already booked using a simple search in the bookedRooms list.
• If available, it adds the customer’s details to the customers list and the room number to the bookedRooms list.

3. Display Booked Rooms

• If the user wants to see the booked rooms, the program loops through the customers list and prints the details of each booking.

4. Check Out

When a customer checks out:

• The program asks for the room number.
• It searches the bookedRooms list for the room number, removes it, and also removes the corresponding customer from the customers list.

5. Exit

• The program will exit when the user selects the "Exit" option.

In this section, we’ll look at an example C++ program that is at an advanced level. Unlike beginner projects focusing on basic concepts like input-output handling and simple control structures, advanced projects demand a deeper understanding of algorithms, data structures, and system-level programming.

1. C++ Snake Game 

The basic Snake game is one of the easiest C++ advanced project ideas where the player controls a snake that moves around the screen. The snake eats food to grow longer while avoiding collisions with walls and itself. The objective is to score as many points as possible by consuming food which appears at random positions on the screen. 

Process and Concepts Involved 

Here are some of the concepts in this example C++ program: 

1. Snake Movement

Concept: The user controls the movement of the snake via arrow keys. The snake’s position is updated continuously in the game loop.

Process: Basic control structures, loops, and keyboard input handling are used to move the snake and update its position on the screen.

2. Collision Detection

Concept: The game checks for collisions with the walls and the snake’s own body. If the snake hits the wall or itself, the game ends.

Process: Conditional statements are used to compare the snake’s position with the boundaries and its body.

3. Food Generation

Concept: Random positions are generated on the screen for the food. When the snake’s head reaches the food, it grows in size, and the score increases.

Process: Random number generation is used to place the food in different positions. The snake's body is represented as an array that grows each time it eats food.

4. Game Loop

Explanation: The game operates in a continuous loop that updates the snake’s position, checks for collisions, and redraws the screen regularly.

Concept: The game loop handles the game's core mechanics, continuously refreshing the game state.

5. Basic Graphics Rendering (Console-based)

Concept: Since the game runs on a console, the snake and food are rendered using ASCII characters. The screen is cleared and redrawn after each frame.

Process: Simple rendering is done by printing characters at specific positions on the console screen.

6. Score Tracking

Concept: The score increases each time the snake eats food. The score is displayed on the screen.

Process: The score is tracked using a variable that is incremented each time the snake consumes food.

7. Game Over Condition

Concept: The game ends when the snake collides with the wall or itself. A message is displayed to inform the player, and the game loop terminates.

Process: The game checks for game-ending conditions inside the loop and ends the game when the condition is met.

Algorithm 

Step 1: Initialise the Game

Set up the game variables:

• Define the game area (height and width).
• Initialise the snake’s starting position.
• Set the initial direction of movement.
• Generate the first food position randomly.
• Set gameOver = false.

Step 2: Game Loop (Runs Until Game Over)

1. Display the Game Board

• Clear the screen.
• Draw the borders of the game area.
• Render the snake on the board.
• Render the food at its position.
• Display the current score.

2. Take User Input for Movement

• Check if a key has been pressed (e.g., W, A, S, D or arrow keys).
• Update the snake’s direction based on the keypress.

3. Update the Snake's Position

• Move the snake in the current direction.

Check for collision with walls or itself: 

• If a collision occurs, set gameOver = true.

If the snake eats the food:

• Increase the snake’s length.
• Increase the score.
• Generate new food at a random position.

4. Introduce a Small Delay

• Add a small delay to control the speed of the snake.

Step 3: End the Game

When gameOver = true:

• Display the final score.
• Show a “Game Over” message.
• End the program.

Code

#include <iostream>
#include <unistd.h> // For usleep()

using namespace std;

bool gameOver;
const int width = 20;
const int height = 17;
int x, y, fruitX, fruitY, score;
int tailX[100], tailY[100];
int nTail;
enum eDirection { STOP = 0, LEFT, RIGHT, UP, DOWN };
eDirection dir;

void Setup() {
    gameOver = false;
    dir = STOP;
    x = width / 2;
    y = height / 2;
    fruitX = rand() % width;
    fruitY = rand() % height;
    score = 0;
}

void Draw() {
    system("clear"); // "cls" for Windows, "clear" for Linux
    for (int i = 0; i < width + 2; i++)
        cout << "#";
    cout << endl;

    for (int i = 0; i < height; i++) {
        for (int j = 0; j < width; j++) {
            if (j == 0)
                cout << "#";
            if (i == y && j == x)
                cout << "O"; // Snake head
            else if (i == fruitY && j == fruitX)
                cout << "F"; // Fruit
            else {
                bool print = false;
                for (int k = 0; k < nTail; k++) {
                    if (tailX[k] == j && tailY[k] == i) {
                        cout << "o"; // Snake body
                        print = true;
                    }
                }
                if (!print)
                    cout << " ";
            }
            if (j == width - 1)
                cout << "#";
        }
        cout << endl;
    }

    for (int i = 0; i < width + 2; i++)
        cout << "#";
    cout << endl;

    cout << "Score: " << score << endl;
    cout << "Enter move (WASD): ";
}

void Input() {
    char input;
    cin >> input; // Waits for user input

    switch (input) {
        case 'a': case 'A': dir = LEFT; break;
        case 'd': case 'D': dir = RIGHT; break;
        case 'w': case 'W': dir = UP; break;
        case 's': case 'S': dir = DOWN; break;
        case 'x': case 'X': gameOver = true; break;
    }
}

void Logic() {
    int prevX = tailX[0];
    int prevY = tailY[0];
    int prev2X, prev2Y;
    tailX[0] = x;
    tailY[0] = y;
    for (int i = 1; i < nTail; i++) {
        prev2X = tailX[i];
        prev2Y = tailY[i];
        tailX[i] = prevX;
        tailY[i] = prevY;
        prevX = prev2X;
        prevY = prev2Y;
    }

    switch (dir) {
    case LEFT: x--; break;
    case RIGHT: x++; break;
    case UP: y--; break;
    case DOWN: y++; break;
    default: break;
    }

    if (x >= width) x = 0; else if (x < 0) x = width - 1;
    if (y >= height) y = 0; else if (y < 0) y = height - 1;

    for (int i = 0; i < nTail; i++)
        if (tailX[i] == x && tailY[i] == y)
            gameOver = true;

    if (x == fruitX && y == fruitY) {
        score += 10;
        fruitX = rand() % width;
        fruitY = rand() % height;
        nTail++;
    }
}

int main() {
    Setup();
    while (!gameOver) {
        Draw();
        Input();
        Logic();
        usleep(100000); // Sleep for 100ms
    }
    cout << "\nGame Over! Final Score: " << score << endl;
    return 0;
}

‍How The Code Works

Here’s how the C++ snake game code works: 

1. User Input Handling

• The program detects key presses using _kbhit() from the conio.h library.
• _getch() captures the key, and the snake’s direction updates accordingly.
• The game recognises WASD or arrow keys to change movement direction.

2. Game Initialization

• Variables for snake position, food location, score, and game state are declared.
• The initial snake position is set at the centre of the board.
• The first food item is placed in a random position.
• The gameOver flag is set to false to start the game.

3. Rendering the Game Board

• The Draw() function clears the screen and redraws game elements.
• Borders are created using loops and ASCII characters (#).
• The snake's body and food appear at their respective coordinates.
• The score is displayed at the bottom of the screen.

4. Snake Movement

• The Logic() function updates the snake’s position based on the current direction.
• The head moves forward, and the body follows.
• If the snake reaches the food, its length increases, generating a new food item.
• The movement continues until a collision is detected.

5. Collision Detection

• The program checks if the snake collides with the wall or itself.
• If a collision occurs, gameOver = true, and the loop ends.

6. Game Loop Execution

• The main loop repeatedly calls Draw(), Input(), and Logic().
• The Sleep() function adds a delay to control the snake’s speed.
• When gameOver is true, the loop stops and the final score is displayed.
