Question

C语言，int 用法出错

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main()
{
srand(time(0));
int a,b,times=0;
a=rand()%100+10;
b=rand()%10+1;
while(times<3)
{
int t=0;
printf("%d/%d=____",a,b);
scanf("%d",&t);
if(t!=a/b)
{
printf("wrong\n");
}else
{
printf("right\n");
return 0;
}
times++;
}
printf("Three times have passed");
return 0;
}

系统提示定义a，b，times的时候出错了，麻烦帮我改正过来。

Answer 1

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main()
{
    int a,b,times=0; //移动到这里就好了，标准C语言不支持在代码区进行变量定义
    
    srand(time(0));
    a=rand()%100+10;
    b=rand()%10+1;
    while(times<3)
    {
        int t=0;
        printf("%d/%d=____",a,b);
        scanf("%d",&t);
        if(t!=a/b)
        {
            printf("wrong\n");
        }else
        {
            printf("right\n");
            return 0;
        }
        times++;
    }
    printf("Three times have passed");
    return 0;
}
