Step by Step solution about How to resolve the algorithm Guess the number/With feedback step by step in the C programming language

This C code implements a simple number guessing game. Here's a detailed breakdown of the code:

1. Header Files:

   • The code includes several standard C library header files:
     • <stdlib.h>: For srand() and rand() functions, which generate random numbers.
     • <stdio.h>: For input and output functions like printf() and scanf().
     • <time.h>: For the time() function, which is used to initialize the random number generator.

2. Constants:

   • lower_limit: This is the minimum value of the random number that the program will generate.
   • upper_limit: This is the maximum value of the random number that the program will generate.

3. Function main:

   • This is the entry point of the program.

4. Random Number Generation:

   • srand( time( 0 ) );: This line initializes the random number generator using the current time as a seed. This ensures that the generated random numbers will be different each time the program is run.
   • number = lower_limit + rand() % (upper_limit - lower_limit + 1);: This line generates a random number between lower_limit and upper_limit and stores it in the number variable.

5. Guessing Loop:

   • printf( "Guess the number between %d and %d: ", lower_limit, upper_limit );: This line prompts the user to enter a guess for the random number.
   • The program enters a loop where it continuously prompts the user for guesses until the user guesses correctly or enters an invalid guess.
   • while( scanf( "%d", &guess ) == 1 ): This loop continues as long as the user enters valid integer guesses.
   • if( number == guess ): Inside the loop, this condition checks if the user's guess matches the random number generated.
   • If the guess is correct, it prints "You guessed correctly!" and breaks out of the loop.
   • If the guess is not correct, it prints "Your guess was too high." or "Your guess was too low." and prompts the user to try again.
   • The loop continues until the user guesses correctly or enters an invalid guess.

6. Exit:

   • The program returns 0 from the main function, indicating successful execution.

#include <stdlib.h>
#include <stdio.h>
#include <time.h>

#define lower_limit 0
#define upper_limit 100

int main(){
  int number, guess;

  srand( time( 0 ) );
  number = lower_limit + rand() % (upper_limit - lower_limit + 1);

  printf( "Guess the number between %d and %d: ", lower_limit, upper_limit );

  while( scanf( "%d", &guess ) == 1 ){
    if( number == guess ){
      printf( "You guessed correctly!\n" );
      break;
    }
    printf( "Your guess was too %s.\nTry again: ", number < guess ? "high" : "low" );
  }

  return 0;
}
