For file operations, look up the fstream header. The basic code looks something like this:

 c++ Syntax (Toggle Plain Text) 
#include <fstream>
 
using namespace std;
 
int main()
{
  fstream file;
 
  file.open( "whatever.whatever" );
  // Check to make sure the file is open with file.is_open()
  // Read data line by line using file.getline(); works just like cin.getline()
  // You can use file.eof() to check if you're at the end of the file (eof stands for end of file)
  file.close();
 
  return 0;
}
#include <fstream>

using namespace std;

int main()
{
  fstream file;

  file.open( "whatever.whatever" );
  // Check to make sure the file is open with file.is_open()
  // Read data line by line using file.getline(); works just like cin.getline()
  // You can use file.eof() to check if you're at the end of the file (eof stands for end of file)
  file.close();

  return 0;
}
