How do I combine variables two at a time.

I am trying to automatically combine variables 1 and 2, 3 and 4, 5 and 6, and so on automatically so I can print them to the screen simular to
cout << 1 <<" "<< 2 << endl;
But instead it would simply be
cout << 1 << endl;

What I have tried:

#include <iostream>
#include <vector>
#include <fstream>
int main( void )
{
    std::string word;
    std::vector<std::string> file;

    std::ifstream in( "Files.txt" );

    while ( in >> word )
        file.push_back( word );

    for ( size_t i=0; i<file.size(); i++ )

        std::cout<< file.at(1) << '\n';
    in.close();

    return 0;
}

Where are the variables in question, what do they contain, and how are you trying to combine them?

should be very easy

C++

int main( void )
{
    std::string text;
    std::string word;
    std::vector<std::string> file;

    std::ifstream in( "Files.txt" );

    while ( in >> word ) {
        //file.push_back( word );
        text += word;
    }
    // easy print out of the full text
    cout << text << endl;
