v.pop_back();
for(int i=1; i<=v.back(); i++) ans++;

写那么长干嘛？？

附上我的代码：

#include <bits/stdc++.h>
using namespace std;
int main() {
    int a,b;
    cin >> a >> b;
    cout << a+b;
    return 0;
}

直接输出呗

#include <iostream>
using namespace std;
int main() {
    int a,b;
    cin >> a >> b;
    cout << a+b;
    return 0;
}

#include <cstdio>
using namespace std;
int main() {
    int a,b;
    cin >> a >> b;
    printf（"%d",&a+b）;
    return 0;
}

直接这样不就行了吗：

#include<iostream>
using namespace std;
int main()
{
    int a,b;
    cin>>a>>b;
    cout<<a+b<<endl;
    return 0;
}

那么烦干什么？？？？
