大概是没开 `long long` 吧（我不知道代码是什么）。

记得开long long，数据范围是不小的。

一种数据类型，比int范围大 @[adjkhdhv_eber](/user/1173230)

```
#include<bits/stdc++.h>
using namespace std;
int a[100005],b[100005],c[20015],jinw,n,m;
int main()
{
string a1,b1;
cin >> a1 >> b1;
n = a1.length();
m = b1.length();
for(int i = n - 1;i >= 0;i--)a[n - 1 - i] = a1[i] - '0';
for(int i = m - 1;i >= 0;i--)b[m - 1 - i] = b1[i] - '0';
n = max(n,m);
for(int i = 0;i < n;i++)
{
c[i] = a[i] + b[i] + jinw;
jinw = c[i] / 10;
c[i] = c[i] % 10;
}
if(jinw>0){
c[n++]=1;
}
for(int i=n-1;i>=0;i--){
cout<<c[i];
}
return 0;
}

@[adjkhdhv_eber](/user/1173230) 没有用long long
by xjj110626 @ 2023-11-24 16:03:18
```cpp
#include<iostream>
using namespace std;
int main(){
long long a, b;
cin >> a >> b;
cout << a + b;
return 0;
}//就是这样
```
