一个简单的随机函数

#include<stdlib.h>
#include<stdio.h>
main()
{
 int a,b,c,x=0;
 while(x<5)
 {a=rand()%100;
  b=rand()%100;
  if(a+b>100)
      continue;
  printf("\\n%d+%d=? ",a,b);
  scanf("%d",&c);
  if(c==a+b)
  {printf("the answer is right");
  x++;
  }
  else
  {printf("The answer is wrong");x=0;

  }

 }printf("\\n program is over");

}
