一个RE，明明外面能运行……题解全是C++我有点想直接去学又怕基础不够

#include<stdio.h> 
int main()
{
    int x,y;
    char z;
    scanf("%d %d %c",&x,&y,&z); 
    if(z=='+')
    printf("%d",x+y);
    if(z=='-')
    printf("%d",x-y);
    if(z=='*')
    printf("%d",x*y);
    if(z=='/')
    printf("%d",x/y);
    if(y==0&&z=='/')
    printf("Divided by zero!");
    if(z!='+'&&z!='-'&&z!='*'&&z!='/')
    printf("Invalid operator!");
    return 0;
}

@RanMagie 把scanf读入改成cin读入

@RanMagie divided by zero要放在第一个，且输出后return，否则除以0会出现RE的错误。

可以输入 1 0 / 测试

@planet_over_for_ever 帖子已经很明确是C语言了

@ppip 提示我是c,但是为什么看起来和c++那么像

by ppip @ 2023-01-28 20:11:01

@planet_over_for_ever 你说得对

by Dian_ed @ 2023-01-28 20:14:17

@planet_over_for_ever 好像相通的吧？毕竟本来差别就不太大

@ppip 感谢！过啦

热知识：gcc编译通过无警告的c语言代码大部分情况下当做c++代码也是可以的

@五个下划线 auto（）

虽然C没人用auto就是了

~~玩梗，非杠~~
