Read certain lines from a file

[panadol]

I want to read certain lines from a file. Let say if the line contains word "makes", the line will be loaded on the screen. Can anyone help me how to modify this code. Thanks by the way.

// reading a text file
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main () {
  string line;
  ifstream myfile ("example.txt");
  if (myfile.is_open())
  {
    while ( getline (myfile,line) )
    {
      cout << line << '\n';
    }
    myfile.close();
  }

  else cout << "Unable to open file"; 

  return 0;
}
