Question

#include <stdio.h>

int main()
{
int n;
printf("Please input n:\n");
scanf("%d",&n);

int a; a = n/100;
int b; b = n%100;
int sum,sub,multi,mod;
float dev;
printf("sum=%d\n",sum = a + b);
printf("sub=%d\n",sub = a - b);
printf("multi=%d\n",multi = a * b);
if(b == 0)
printf("The second operater is zero!\n");
else
printf("dev=%.2f\n",dev = a/b);
printf("mod=%d\n",mod = a%b);

return 0；
}

Answer 1

return 0; 这个分号 你这里是中文的 必须改成英文
else 后面要有{ }虽这里不会报错 但是如果b=0的时候 就会报错
