Computer programming uses a code or language that can be placed into several lines of code that can be translated to many different things after being processed as a program. For example, the software you use to calculate your taxes, or the software you use to create your simple web page are all products of skilled computer programming. The following are some of the core functions of computer programming:
Computer Programming Language
A function can be important and thus can be a key concept to learn when one is interested in software and computer programming. Functions may also be referred to as subroutines, procedures, or subqueries. How is function important? For example, if a company or institution has a library of many different programs, then these programs can consist of millions of lines of source code. In the interest of time and space, you want to avoid duplicating certain source code in many different places.
Computer Programming Duplication
If source code is duplicated in a lot of different places, it’s copied in vain, and that can spell Hell for programmers and troubleshooters when things go wrong down the line. If the source code is actually wrong, the programmer or troubleshooter has to fix the code in all the different places it appears. If the source code must be updated or upgraded to make the program run faster or perform more operations, then the source code must be modified, upgraded, and updated everywhere it appears. And if source code is to be removed and replaced with new source code, it must be deleted and replaced with new code in every place it appears.
Creating Programs is time consuming
Granted programming is time consuming, and can lead to more errors because of all the human intervention that has to go through. On the other hand, if there is a function built in to handle all the different programs then only one or a few changes will have to be made if something goes wrong, or if the source code has to be updated, modified, enhanced, or changed. You can think of its function as an umbrella: it includes all the different programs under it, so you don’t have to cover each program separately.
Program Source Code
Having a single source code that acts as a function is also an advantage when you have to introduce a new program that still uses the same source code. Since the source code is already available as an entire function or sub-program, you don’t need to add source code to a new program. You just need to find a way for the new program to interact with the source code itself.
