Steps followed to code the program
First the concept of simple graphic program was built up and for which Brick game is the simplest for coding. The simple diagrams of program were constructed and raw codes were collected and written. Different functions were created to do individual task. The module was coded and the user defined functions were included in the module. The errors were debugged and the program was launched in Turbo C environment.
