C++ how to read from a file

#include <fstream>
#include <iostream>

using namespace std;

int main() {
    /* You create a stream using the file in a 
     * similar way to how we use other streams.
     */
    ifstream in;
    // Open the file
    in.open("names.txt");
    if(in.fail())
        cout << "File didn't open"<<endl;

    int count = 0;
    string line;
    while (true) {
        /* Get line will work as long as there is
         * a line left. Once there are no lines 
         * remaining it will fail. 
		 */
        getline(in, line);  
        if (in.fail()) break;
        
        /* Process the line here. In this case you are
         * just counting the lines.
         */
        count ++;
    }
    
    cout << "This file has " << count << " lines." << endl;
    return 0;
}
