GTK Initialization

Every GTK program needs to first initialize the GTK library. This is done using the following piece of code:

 int
 main(int argc, char* argv[]);
 {
     .
     .
     /* This is called in all GTK applications. Arguments */
     /* are parsed from the command line and are returned */
     /* to the application.                               */
     gtk_init(&argc, &argv);
     .
