reading names

closed account (i8bjz8AR)
so i have to write a small text filter that filters through a file, b.list, and outputs each name (first and last) of each actor. The b.list file contains movies and these actors names. Can't figure out how to output only the names. Here is what i have so far. We can only use things like

std::string s;
while(std::getline(std::cin, s))
  std::cout << s.size();


std::string s = "abc def";
std::size_t n = s.find(' '); // Find the index of the first ' '
std::string first = s.substr(0, n);
std::string second = s.substr(n + 1);

std::string s = "hello";
std::cout << s[0] << '\n'; // prints 'h'
s[0] = 'y';                // modify the first character
std::cout << s[0] << '\n'; // prints 'y'
std::cout << s << '\n';    // prints "yello"


which is an example they gave us

#include <iostream>
int main()
{


    for(b.list = 0; b.list <= ){
        cout s[i]

    }

  std::size_t n = s.find(' '); // Find the index of the first ' '


  std::string s;
  while(std::getline(std::cin, s))
    std::cout << s;



  return 0;
}


and here is a list of the file we have to filter through with movies and actors names

It looks like (though I may be wrong) the file uses the tab character '\t' as a delimiter, after the actor's name. If that is so, you could read the whole line and use the first '\t' to identify the end of the name.

(or possibly use getline with a tab delimiter, then a 'normal' getline with a newline delimiter).

That makes sense to me but I have no idea how I would do it

Look at lines 8 and 9 of your first example (find and substr). Just needs adapting to use tab instead of space - assuming this does indeed fit the file format.
