本蒟蒻啥都不会，只能贡献一份小小的码风优良的代码```language

#include <iostream>
using namespace std;

const int MAX = 1000;

void change(const string &a1, int a[], int len)
{
	for (int i = 0; i < len; i++)
	{
		a[i] = a1[len - i - 1] - '0';
	}
}

int main()
{
	string a1, b1;
	cin >> a1 >> b1;
	int lena = a1.size(), lenb = b1.size();
	int a[MAX] = {}, b[MAX] = {}, c[MAX] = {}, cf = 0;
	change(a1, a, lena);
	change(b1, b, lenb);
	int lenc = lena;
	if (lenb > lena)
	{
		lenc = lenb;
	}
	for (int i = 0; i <= lenc; i++)
	{
		c[i] = a[i] + b[i] + cf;
		if (c[i] >= 10)
		{
			cf = 1;
			c[i] -= 10;
		}
		else
		{
			cf = 0;
		}
	}
	int i = lenc;
	if (c[i] == 0)
	{
		i--;
	}
	for (i; i >= 0; i--)
	{
		cout << c[i];
	}
	return 0;
