GUESSING THE NUMBER USING C

INTRODUCTION

The Number Guessing Game is a simple yet engaging program designed to test and improve the user’s logical thinking and problem-solving skills. It combines basic concepts of programming logic, loops, and conditional statements to create an interactive experience.

Features of the Game:

Random Number Generation: The game generates a random number between 1 and 100, ensuring each session is unique.
User Interaction: It allows the user to repeatedly guess the number, providing feedback on whether the guessed number is too high, too low, or correct.
Dynamic Gameplay: The program tracks the number of attempts taken by the user to guess correctly and displays it at the end.
Real-Time Feedback: After every guess, the game provides hints, guiding the user toward the correct answer.

Purpose of the Game:

Learning Tool: Serves as a great project for beginners to practice key programming concepts like randomization, loops, and conditions.
Fun and Challenge: Offers an entertaining way to challenge oneself in predicting numbers within the shortest number of guesses.

CODE SNIPPETS

#include <stdio.h>
#include <stdlib.h> // For rand() and srand()
#include <time.h>   // For time()

int main()
{
    // Initialize random number generator with current time as seed
    srand(time(0));

    // Generate a random number between 1 and 100
    int randomNumber = (rand() % 100) + 1;
    int guessed_number;
    int no_of_guesses = 0;
    do
    {
        printf("Enter your number : ");
        scanf("%d", &guessed_number);
        if (guessed_number > randomNumber)
        {
            printf("Lower Number Please !\n");
        }
        else if (guessed_number < randomNumber)
        {
            printf("Higher Number Please !\n");
        }
        else
        {
            printf("Congrats,You Guessed it Right !\n");
        }
        no_of_guesses++;

    } while (guessed_number != randomNumber);

    // Print the random number
    // printf("Random number between 1 and 100: %d\n", randomNumber);
    printf("You guessed in %d guesses\n",no_of_guesses);

    return 0;
}

OUTPUT

Code Explanation

#include <stdio.h>
#include <stdlib.h> // For rand() and srand()
#include <time.h>   // For time()

Introduction:

#include <stdio.h>: Provides input/output functions (printf, scanf).
#include <stdlib.h>: Includes rand() for generating random numbers and srand() for seeding randomness.
#include <time.h>: Provides time() to seed the random number generator dynamically.

int main()

Purpose: The entry point of the program where execution begins.

srand(time(0));

Functionality:

Seeds the random number generator with the current system time.
Ensures different random numbers are generated each time the program runs.

int randomNumber = (rand() % 100) + 1;

Purpose:

Generates a random integer between 1 and 100.
- rand() % 100: Limits the random number range to 0–99.
- + 1: Shifts the range to 1–100.

int guessed_number;
int no_of_guesses = 0;

Variable Initialization:

guessed_number: Stores the user’s input during the game.
no_of_guesses: Counts the total number of attempts the user takes to guess correctly.

do
{
    printf("Enter your number : ");
    scanf("%d", &guessed_number);

Gameplay Loop:

A do-while loop is used to repeatedly prompt the user for guesses until the correct number is guessed.
printf: Prompts the user to input a number.
scanf: Reads the user’s input and assigns it to guessed_number.

if (guessed_number > randomNumber)
{
    printf("Lower Number Please !\n");
}

Checks if the guessed number is greater than the random number.
If true, prompts the user to guess a lower number.

else if (guessed_number < randomNumber)
{
    printf("Higher Number Please !\n");
}

Checks if the guessed number is less than the random number.
If true, prompts the user to guess a higher number.

else
{
    printf("Congrats,You Guessed it Right !\n");
}

Triggered when the guessed number matches the random number.
Congratulates the user for guessing correctly.

no_of_guesses++;

Purpose:

Increments the no_of_guesses counter after each attempt, regardless of the outcome.

} while (guessed_number != randomNumber);

printf("You guessed in %d guesses\n", no_of_guesses);

Loop Continuation:

The do-while loop continues until the user’s guess matches the random number.

End of Game:

Displays the total number of attempts the user took to guess the random number correctly.

How the Program Works

Game Start:
- A random number is generated between 1 and 100.
- The user is prompted to guess the number.
Gameplay:
- The program provides hints after each guess, indicating whether the user should guess higher or lower.
- The process repeats until the correct number is guessed.
End of Game:
- The program congratulates the user and displays the total number of attempts made.

Improvements

Error Handling:
- Add checks to ensure the user inputs valid integers.
- Handle scenarios where input is non-numeric to avoid program crashes.
Dynamic Range:
- Allow the user to select the range for the random number (e.g., 1–1000).
Enhanced Feedback:
- Add encouraging messages for near guesses.
- Include a leaderboard to track the fewest guesses for multiple players.
