Fast Help for Data Structures?

[adriyel]

So I made a code that shows a simple rectangle. How do I make it move using data structures? :)


CODE:
#include "Glut_Setup.h"
#include <stdlib.h>
#include <stdio.h>
#include <iostream>
#include <vector>
#include <time.h>

using namespace std;




float P1= -5;
float P2= 2;
float P3= 5;
float P4= -2;


struct first{
float x, y, z;
}A;

struct second{
float x, y, z;
}S;


void GameScene()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);


void show(struct first, second);
{
glPushMatrix();
glBegin(GL_QUADS);
glColor3f(1.0, 1.0, 1.0);
glVertex3f(P2, P1, 0);
glVertex3f(P2, P3, 0);
glVertex3f(P4, P3, 0);
glVertex3f(P4, P1, 0);
glEnd();
glPopMatrix();

}
glutSwapBuffers();

}

void Keys(unsigned char key, int x, int y)
{
switch(key)
{

}
}

void SpecialKeys(int key, int x, int y)
{
switch(key)
{

}
}

void Timer(int value)
{
glutTimerFunc(50, Timer, value);
glutPostRedisplay();
}

void changeSize(int w, int h)
{
float ratio = 1.0 * w / h;
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glViewport(0, 0, w, h);
gluPerspective(45, ratio, 1, 1000);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
gluLookAt(0.0, 0.0, 30.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0);
}

void main(int argc, char **argv)
{

srand(time(NULL));
GLUTInit(&argc, argv);
}

Do you know what a data structure is?

@adriyel: You don't animate anything with a data structure.
