Coding, also known as programming, refers to the process of creating instructions that computers follow to execute specific tasks or solve problems. This foundational aspect of modern technology powers everything from simple mobile apps to complex artificial intelligence systems. Let’s understand what is coding in this article.
History and evolution of coding have passed through various periods over decades of significant achievement;
Early days’ coding was initially undertaken using machine language by use of binary code (0s and 1s), it was hectic and erroneous.
Assembly Language: Essentially a superset of machine language, assembly language uses symbolic forms of binary instructions that make writing easier, though the computer architecture must still be pretty well understood.
High-Level Languages: Even though they were created during the 1950s and 1960s, languages such as FORTRAN and COBOL were able to attain a much higher level of abstraction because it was possible to write commands in a rather English-like format, taking much of the machine-level complexity out of sight.
Modern programming languages are numerous today, and each one has a certain strength and domain of application. Popular languages such as Python, Java, and JavaScript offer an extensive set of features and libraries that allow one to develop very powerful software.
Basically, coding is the procedure involved in creating a series of instructions that a computer will execute. Such instructions are generally divided into some basic constructs, such as variables together with data types for storing and manipulating data like numbers, text, and logical values, and control structures such as conditionals and loops, which direct the flow of execution of a program.
Functions and Procedures: These are reusable blocks of instructions that execute specific tasks; these may be called for execution at will.
Data Structures: It refers to methods of organizing and storing data, such as by arrays and lists, which provide efficient facilities for performing operations on the data.
There may be different styles or methodologies to write code; these are called programming paradigms. Some of them are as follows:
Procedural Programming: It is based upon procedure calls. Under this paradigm, code is organized in reusable blocks called procedures, routines, or functions.
Object-Oriented Programming: This paradigm is based on "objects", class instances. OOP brings to the front the ideas of encapsulation, inheritance, and polymorphisms to deal with complex setups more coherently.
Functional: It takes computation as an evaluation of mathematical functions and avoids changing-state or mutable data. This leads to obvious and predictable clearness observable in its code.
Declarative Programming: This would concern what should be achieved, not how to achieve it. It is characterized by languages for database queries.
