Ignoring lines in c++

[nithishguptak]

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

int main ()
{
  string line,matrix;
  ifstream myfile ("out");
  if (myfile.is_open())
  {
    while (!myfile.eof() )
    {
      getline (myfile,matrix);
      cout << matrix<< endl;

    }
    myfile.close();
  }

  else cout << "Unable to open file";

  return 0;
}

Hello With this code i could read all the lines from the input file.But i need to ignore some lines in the input file how to do that.

use ignore instead of getline
http://www.cplusplus.com/reference/istream/istream/ignore/
myfile.ignore(1000000,'\n');
