[Geany-Users] I want to run a c program on Prisoner's Dilemma in Geany but can't

[bkpsusmitaa]

Here are the 4 execs that have been compiled.

So. the first code is not supposed to work? I am surprised! I had told
you earlier, I have a problem understanding the language people talk
in.

The first code:
----------------------------------
#include <whateverYouNeed.h>

main() {

   InitializeAWindowPlease();

   glClearColor (0.0, 0.0, 0.0, 0.0);
   glClear (GL_COLOR_BUFFER_BIT);
   glColor3f (1.0, 1.0, 1.0);
   glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
   glBegin(GL_POLYGON);
      glVertex3f (0.25, 0.25, 0.0);
      glVertex3f (0.75, 0.25, 0.0);
      glVertex3f (0.75, 0.75, 0.0);
      glVertex3f (0.25, 0.75, 0.0);
   glEnd();
   glFlush();

   UpdateTheWindowAndCheckForEvents();
}
