@yao_123456 我改了为什么还是过不了。。qwp

@Qcrkkl 题目的中间和结尾，即答案和第二个数字的左边，都有一个中文的括号

还是wa了。。

#include<bits/stdc++.h>
using namespace std;
int main()
{
    long long  a,b;
    cin>>a>>b;
    if (a<0) printf("（%I64d)",a);
    else printf("%I64d",a);
    printf("+");
    if (b<0) printf("（%I64d)",b);
    else printf("%I64d",b);
    long long xyg=a+b;
    if (xyg<0) printf("=（%I64d)",xyg);
    else printf("=%I64d",xyg);
    return 0;
}

@Qcrkkl 没有办法……

by wangcm @ 2024-09-15 16:06:43

这题上一次有人AC好像还是去年（上个月）……

by wangcm @ 2024-09-15 16:13:42

听取WA声一片……

#include<bits/stdc++.h>
using namespace std;
int main()
{
    long long a,b;
    cin>>a>>b;
    if(a<0) cout<<"（"<<a<<")";
    else cout<<a;
    cout<<"+";
    if(b<0) cout<<"（"<<b<<")";
    else cout<<b;
    cout<<"=";
    if(a+b<0) cout<<"（"<<a+b<<")";
    else cout<<a+b;

    return 0;
}

已AC

#include<bits/stdc++.h>
using namespace std;
int main()
{
    long long a,b;  
    cin>>a>>b;
    if(a<0){
        printf("%c%c",-93,-88);
        cout<<a<<")";
    }
    else cout<<a;
    cout<<"+";
    if(b<0){
        printf("%c%c",-93,-88);
        cout<<b<<")";
    } 
    else cout<<b;
    cout<<"=";
    if(a+b<0){
        printf("%c%c",-93,-88);
        cout<<a+b<<")";
    }
    else cout<<a+b;

    return 0;
}

@Qcrkkl 错误原因：中文括号占两个字节，需要分开输出。而将中文括号拆为两个ACSII值，便是-93和-88
