Introduction to Computer Programming
Computer programming is a collection of instructions that performs a specified task when executed by a computer. A computer program is usually written by a computer programmer in a programming language. programming can be classified into two types:
1. System programming
System programming is handled by computer engineers or System programmers
to develop system programs such as Operating systems, Language translators.
2. Application programming
Application programming is handled by Ordinary computer programmers to develop application software such as a Payroll System stock control system.
The possibility of programming is a task by a machine is called Computability. A program should produce the required result for all possible inputs, and it is called correctness.
programming that produces a program with a clean flow, clean design and a degree of modularity or hierarchical structure is called structured programming.
Three basic constructs in structure programming are sequence, selection, iteration. An approach to programming in which the program is broken into several independently compiled modules is called modular programming efforts. Programming language is an artificial language that can be used to define a sequence of instructions that can ultimately be processed and executed by the computer.
👉 Languages are generally divided into 5 types.
➤ Machine languages
➤ Assembly languages
➤ High-level languages
➤ Very- High-level languages
➤ Natural languages
