为什么不能全部AC！！！

@C2024_QAQ 还奇妙解法，这不就是高精度吗？（无恶意）你没判负数

by C2024_QAQ @ 2024-07-20 16:46:39

好吧，我好想知道了，这个有负数

by C2024_QAQ @ 2024-07-20 16:49:09

But，请问我要怎么修改才能对

@C2024_QAQ 开long long 会棕名吗？

@CHGM ?

@C2024_QAQ 高精度逝罢

@C2024_QAQ

#include<bits/stdc++.h>
using namespace std;
int main(){
    string a,b;
    cin>>a>>b;
    int a1[100],b1[100],c1[101],x=0;
    memset(a1,0,sizeof(a1));
    memset(b1,0,sizeof(b1));
    memset(c1,0,sizeof(c1));
    for(int i=1;i<=a.size();i++)
        a1[i]=a[a.size()-i]-48;
    for(int i=1;i<=b.size();i++)
        b1[i]=b[b.size()-i]-48;
    int i=1;
    while(i<=a.size()||i<=b.size()){
        c1[i]=(a1[i]+b1[i]+x)%10;
        x=(a1[i]+b1[i]+x)/10;
        i++;
    }
    if(x==1){
        c1[i]=1;
        i++;
    }
    for(int j=i-1;j>=1;j--)
        cout<<c1[j];
    return 0;

@heyichen201209 谢谢

by C2024_QAQ @ 2024-07-20 18:15:18

@heyichen201209 但是……还是错的，错的还是那几个点

by CHGM @ 2024-07-21 08:13:35

@C2024_QAQ 那就开long long啊！int 都能过
