Example

// string::push_back
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main ()
{
  string str;
  ifstream file ("test.txt",ios::in);
  while (!file.eof())
  {
    str.push_back(file.get());
  }
  cout << str;
  return 0;
}

This example reads an entire file character by character, appending each character to a string object using push_back.
