How do I print out the contents of a file? C++ File Stream

#include <iostream>
#include <fstream>

int main()
{
    string name ;
    std::ifstream dataFile("file.txt");
    while (!dataFile.fail() && !dataFile.eof() )
    {
          dataFile >> name ;
          cout << name << endl;
    }

There's no reason to reinvent the wheel here, when this functionality is already implemented in the standard C++ library.

#include <iostream>
#include <fstream>

int main()
{
    std::ifstream f("file.txt");

    if (f.is_open())
        std::cout << f.rdbuf();
}
