不行嘛 我刚接触算法 不太懂

那个arr3[i]=arr1[i]+arr2[i]
应该是arr3[i]+=arr1[i]+arr2[i]
不然无法判断进位

数组位置错了
应该开在第三行
```
#include<iostream>
using namespace std;
int arr1[501], arr2[501], arr3[503];
int main()
{
string s1, s2;
cin >> s1 >> s2;
int len = s1.length();
for (int i = 0; i < len; i++)
{
arr1[len - 1 - i] = s1[i] - '0';
}
len = s2.length();
for (int i = 0; i < len; i++)
{
arr2[len - 1 - i] = s2[i] - '0';
}
if (len < s1.length())
{
len = s1.length();
}
for (int i = 0; i < len; i++)
{
arr3[i] += arr1[i] + arr2[i];
arr3[i + 1] = arr3[i] / 10;
arr3[i] = arr3[i] % 10;
}
if (arr3[len] > 0)
{
len++;
}
for (int i = len-1; i>=0; i--)
{
cout << arr3[i];
}
return 0;
}
```

过了过了 谢谢dalao 不过有啥区别啊 （不懂）

@[Achenfeng](/user/402229) main函数外面定义数组里面默认值都是0，main函数里面定义理论上是随机的值

@[Unknowon_Error](/user/1027359) IOSTREAM咋了？
