                                    • Understand Basic of Programming.

                                    • Explain Levels of Language in Computer Programming.

                                 10.1 Basic of Programming

                                 Computer programming (often shortened to programming or coding) is the process of designing,
                                 writing, testing, debugging / troubleshooting, and maintaining the source code of computer
                                 programs. This source code is written in a programming language. The purpose of programming
                                 is to create a program that exhibits a certain desired behaviour. The process of writing source
                                 code often requires expertise in many different subjects, including knowledge of the application
                                 domain, specialized algorithms and formal logic.
