I switched my interest towards writing a Text Based
pong game.

here's the code which I wrote so far :
Code:
#include <stdio.h>

class tag_ball
{
	public:
	int x, y;
	int oldx, oldy;
} ball;

class tag_paddle
{
	public:
	int x, y
	int oldx;
} paddle;

main()
{
}
This is the most basic code. (Just did 1 minute of work on this.)

I want to make this program as simple as possible (I wrote this
game in Qbasic, but in graphics, but didn't program it really
well. Now that C programs are structured, I want to make the code simple more readable.

Ok, here comes the question.

Whenever I say
paddle.x = 5

I want the paddle class' x variable to be 5. And I want it to
automatically call a function (say, placepaddle, or whatever name)
and run that function, how do I do that ?

in other words, whenever I set the variable, it should automatically call a function that does a particular job.

I know this could be done in classes (that's the reason
why I changed my struct to class), but I don't remember how.
