请问为啥C用long int 反而WA呢？

#include<stdio.h>
int main()
{
    long int a,b;
    scanf("%d %d",&a,&b);
    printf("%ld",a+b);
    return 0;
}

输入？

读入的时候用 %ld .

最好学c++，用cin/cout不用考虑占位符的问题

@Jianbing_Juan 好的，谢谢您

@Li_Hua_13 用c++的cin和cout就不会有问题了

by zengyijian @ 2023-12-09 14:48:04

这么写：

#include<iostream>
using namespace std;
int main(){
    long long a,b;
    cin>>a>>b;
    cout<<a+b;
    return 0;
}

scanf要用%ld啊

by CHkuakeU @ 2023-12-15 08:19:42

scanf不是用%d吗？

by hyh0174 @ 2023-12-15 21:54:38

@CHkuakeU %d输入整数型，%ld输入长整数型，还有%c,%s,%lld等等

@hyh0174 对于本题来说
