Guess the Number Game (1-100) in C++

In this exercise, you will implement a program that simulates a simple number guessing game. The program will generate a random number between 1 and 100, and the player will attempt to guess the number. After each guess, the program will give feedback on whether the guess is too high, too low, or correct. The game will continue until the player guesses the correct number.

The program will use random number generation to select a number within the specified range. The player will input guesses, and the program will compare the guess with the target number, providing appropriate feedback after each guess.

Objective

1. Generate a random number between 1 and 100.
2. Ask the user to guess the number.
3. Compare the user's guess with the generated number.
4. Provide feedback if the guess is too high, too low, or correct.
5. Keep asking for guesses until the user guesses the correct number.
6. Display the number of attempts it took the user to guess correctly.

Implement a program that simulates the number guessing game (range 1-100).

Example C++ Exercise

 Copy C++ Code 
#include <iostream>  // Include input/output stream
#include <cstdlib>     // For random number generation
#include <ctime>       // For seeding the random number generator

using namespace std;

int main() {
    srand(time(0));  // Seed the random number generator with the current time
    int targetNumber = rand() % 100 + 1;  // Generate a random number between 1 and 100
    int guess;  // Variable to store the player's guess
    int attempts = 0;  // Counter for the number of attempts

    // Introduce the game to the user
    cout << "Welcome to the Guess the Number Game! The number is between 1 and 100.\n";

    // Start the game loop
    do {
        cout << "Enter your guess: ";  // Prompt the user to enter a guess
        cin >> guess;  // Store the user's guess
        
        attempts++;  // Increment the attempt counter

        if (guess < targetNumber) {
            cout << "Your guess is too low. Try again.\n";  // If guess is too low, provide feedback
        } else if (guess > targetNumber) {
            cout << "Your guess is too high. Try again.\n";  // If guess is too high, provide feedback
        } else {
            cout << "Congratulations! You've guessed the number in " << attempts << " attempts.\n";  // If guess is correct, congratulate the user
        }
    } while (guess != targetNumber);  // Continue the loop until the correct guess is made

    return 0;  // Return 0 to indicate successful completion of the program
}

 Output

Welcome to the Guess the Number Game! The number is between 1 and 100.
Enter your guess: 50
Your guess is too high. Try again.
Enter your guess: 25
Your guess is too low. Try again.
Enter your guess: 37
Your guess is too low. Try again.
Enter your guess: 43
Your guess is too low. Try again.
Enter your guess: 47
Your guess is too high. Try again.
Enter your guess: 45
Congratulations! You've guessed the number in 6 attempts.
