im wokring on a project that lists DVD's in a linked list to a Output File and I was wondering if they is a way to make every other one a different color so that way it went black to say red black red black red and alternated. i know there is a system color command but does that only work when you run it though dos?

Thanks for your guys help

Standard text files (ASCII files) do not have color attributes, so no.
Unless you a writing to a different file format.

You could output to HTML.

I'm not exactly clear as to where you want the colors. Embedded in the text file? You could try ANSI escape sequences but the key will be how/where you display the file to interpret them. Colored as it displays? Look into ncurses.

That is a brilliant idea. (Assuming the OP can support displaying it)

#include <string>
#include <vector>
using namespace std;

int main()
  {
  vector <string> v;
  v.push_back( "one" );
  v.push_back( "two two" );
  v.push_back( "three three three" );
  v.push_back( "one two three four" );
  v.push_back( "the end" );

  cout << ( write_html( "test.html", v )
          ? "yeah!\n"
          : "fooey!\n");
  return 0;
  }
Edit & run on cpp.sh

Simple and, well, simple.
