Simple Animation to Fill Box color using C Program

Program #18

Description:
Dynamically plotting dots on a specific area in the screen using multi-colors.  Once all positions plotting is done.  Program will come to an end.

Draw a box in C Program

Program #13

Description:
Draw a box dynamically in the screen based on co-ordinates and box size.

   getch();
   /* Stop the Execution */
   abort();
 }

 scanf("%d",&boxSize);

/* Validate possibility of Drawing Box */

   getch();
   /* Stop the Execution */
   abort();
 } else if ((y+boxSize) > 25){
   printf("Invalid Y Co-ordinate!!");
   getch();
