下面是C语言猜数游戏的源代码：
#include "stdafx.h"
#include
#include
#include
#define NO 0
#define YES 1

int _tmain(int argc, _TCHAR* argv[])
{
int guess_value=-1;
int n;
int nbr_of_guesses;
int done=NO;
int rand();
printf("\n\nGetting a Random number\n");
srand((unsigned)time(NULL));
n=rand()%100;
nbr_of_guesses=0;
while(done==NO)
{
printf("Pick a number:\n");
scanf("%d",&guess_value);
nbr_of_guesses++;
if(n==guess_value)
{
done=YES;
}
else if(n<guess_value)
{
printf("\nYou guessed high!");
}
else
{
printf("\nYou guessed low!");
}
}
printf("\n\nCongratulations!You guessed right in %d Guesses",nbr_of_guesses);
printf("The number was %d\n\n",n);

return 0;
}

不足之处，还望指教！
