Detecting EOF for cin

This is the template for 3n+1.

#include <iostream>
#include <string>

using namespace std;

int main()
{
  int i, j;
  while(cin >> i >> j) {
    // ...
  }
}

Detecting EOF for getline

You can use std::getline to read the whole line. The following is the template for TEX quotes. You can access string length with length method and you can access each character using []. See reference here.

#include <iostream>
#include <string>

using namespace std;

int main()
{
  string st;
  while(getline(cin, st)) {
    // ...
  }
}
