Computer programming is the procedure of building and designing an ordered computer program either to carry out a certain activity or to achieve a definite computing result. Programming is usually done with the aid of computers and its programs. This is mostly to ensure that a particular program will work in a predictable manner when given a certain input. It is very important for people who have a knack in using computers to produce and design programs to be more efficient so they can give better services to their clients.
The computer programmers can take any object and turn it into a program. The process of programming can be done manually, but nowadays, a lot of companies are turning to programmers to get the job done because it can be time consuming. In order for us to understand the essence of computer programming, we first need to know what it is. So let us start with a little history.
Before computers came into being, people had to be trained in how to program because they only use symbols and numbers as instructions. For example, if you were to create a game, you would have to be able to code the different moves your character would make. These move codes are later stored in memory chips, which are used by computers to later translate the instructions into the coded information. Thus, programmers needed to be highly skilled so they can translate the instruction directly into code that the computers can understand.
A programmer is a person who designs and modifies programs. They create and give instructions to computers in the form of instructions. If the instruction is translated directly to computer code, the computer will then execute it. Usually, all programmers are one in the same. The only difference between them is their job description, or the task they are assigned. They can be independent contractors who work for various companies in the name of programming.
There are three types of programming languages. These are high-level programming, middle-level programming and low-level programming. In middle-level programming, the programmer will receive instructions and translate these into specific task-related instructions. The task-related instructions are commands the programmer gives to the computer. They can be adding 2 numbers together or tell the computer to print a document.
There are also two kinds of level of source code. The top level source code refers to any information directly stored by the computer programming languages as well as any information accessed by the computer programmers through the source code. Low level source code on the other hand refers to any data directly accessed by the programmers through a series of instructions. This means the computer programmers should know how to readability check for syntax errors. If the source code syntax error is detected, the programmer should immediately stop the execution and reschedule it to another day.
Programming languages are divided into two categories. These are high-level programming and low-level programming. Both these categories are different in terms of the source code generated during the development. The higher level programming languages are more readable than the lower level ones, while the lower level languages are more readable than the higher level ones.
Computer programming languages are classified as high/low/lexical/stack programming languages. In stack programming language, the computer code is stored in a stack like a reference. A lexical programming language does not use any stack but instead creates and stores a single value at a time. High/low programming languages, on the other hand, use a stack for both the source code and the destination of the code’s execution. Stack programming languages are the best option for beginners.
