Question

What I want to do is read a line from text file which contains a two word string which has a length <= 20 and two integers, for example it may look something like this:

Name Surname 1 14

I know that if I read string, the string will be all characters until the white space, however getline() reads the whole line as a string. So how do I read a line like this ? Is there any easy way or I will have to use regular expressions ?

Maybe…

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main()
{
    ifstream file( "/home/facu/text.txt", ios::in );
    string part1, part2;
    int num1, num2;

    if( !file )
        cerr << "Cant open " << endl;

    while( file >> part1 >> part2 >> num1 >> num2 )
    {
        cout << part1 << " " << part2 << " " << num1
        << " " << num2 << endl;
    }

    file.close();
    return 0;
}

Where text.txt:
