짦은 지식이라 모르겟습니다..

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

void main(void)
{
        int guess_value = -1;

        int number; //렌덤해서얻은수
        int nbr_of_guesses = 0;
        int done = 0;

        printf("\n\nGetting a Random number\n");

        srand( (unsigned) time (NULL) ); //시간으로렌덤해서수얻기
        number = rand(); //얻은수대입하기

        while(done == 0)
        {
                printf("\nPick a number between 0 and %d> ", RAND_MAX);
                scanf("%d", &guess_value);

                nbr_of_guesses++;

                if(number == guess_value)
                {
                        done = 1;
                }
                else
                        if(number < guess_value)
                        {
                                printf("\nYou guessed high!");
                        }
                        else
                        {
                                printf("\nYou guessed low!");
                        }
        }
        printf("\n\nCongratulations! You Guessed right in %d Guesses!", nbr_of_guesses);
        printf("\n\nThe number was %d\n\n", number);
}
