Làm bằng lập trình c++ mình cần gấp

`Code:`

#include<bits/stdc++.h>
using namespace std;
#define fastread() (ios_base:: sync_with_stdio(false), cin.tie(NULL), cout.tie(NULL))

int a, b, c, d, e;

void solve(){
 cin >> a >> b >> c >> d >> e;
 int sum = a + b + c + d + e;
 string sum1 = to_string(sum); 
 cout << sum << "\n" << sum1[sum1.length() - 2] << " " << sum1[sum1.length() - 1];
}

int main(){
 fastread();
 solve();
return 0;
}
