使用if … else语句猜一个随机数

#include <stdio.h>

#include <stdlib.h>
int main(void)
{
   int magic; /* magic number */
   int guess; /* user's guess */

   magic = rand(); /* generate the magic number */

   printf("Guess the magic number: ");
   scanf("%d", &guess);

   if (guess == magic) printf("** Right **");
   else printf("Wrong");

   return 0;
}
