Reading multiple lines in c++ if the file is unknown

Question

I got in a file bac.txt 2 different lines and I got to read both of them,what can I do in this situation?

Answer 1

You should use standard function std::getline with argument of type std::string and after that use std::istringstream to parse each line.

For example

#include <iostream>
#include <fstream>
#include <sstream>
#include <string>

//...

std::string line;

while ( std::getline( YourFile, line )
{
   std::istringstream is( line );
   // using `operator >>` to read items in the line
}
