Marquee Display (Recommended IDE DEV-C++)

Through assignment 1 youve developed your first animated program in C. The sample solution is attached with this assignment to show you how a novice programmer may have done it.

This sample solution is poorly written and have multiple places to improve. The goal of this assignment is to revise the sample code for improved maintainability and readability.

Refactoring Improving Code Maintainability without changing the functionalities of the program

Task 1 Function Encapsulation

The sample solution contains a ludicrous number of copy-and-paste code segments. Encapsulate them into functions and call them using some sort of repetition control structure.

Task 2 No Magic Number

Some parameters in the code are obviously constants that would affect the overall behavior of the program. Separate them out using proper pre-processor constant definition, so that you can easily find them and change them in bulk.

Task 3 Traceable Exit Point

The main program loop appears to be an infinite loop. Youd have to read hard to find where the exit condition is located. Do something so that the while loop deploys a very clear exit condition for ease of management.
