In computer programming, the term code refers to source code and machine code. Source code is a sequence of statements written in a computer programming language, which can be easily deciphered. On the other hand, machine code is a set of instructions executed directly by the computer's CPU. It is a representation of a compiled computer program. A block of code written by a programmer is the core element of every web & software development process. Let us learn a bit more about source code:Source Code (commonly referred to as Source): Source code is a set of statements written in a human-readable programming language. It lets you use a reserved number of instructions to communicate with the computer. The source code is usually saved in one or more text files. Mostly, a large set of source code files is organized into a directory tree, also known as source tree. Source code is mainly used as an input to the process that creates an executable program. In simpler terms, it has to be converted from a human-readable format into a type of computer-executable form with the help of a compiler or with the help of an interpreter. How Programmers Enhance their Programming Skills with Source Code? Programmers are always eager to learn more about programming techniques for a successful software and web application development process. That's why they find it very helpful to review any existing source code and so they always share source code to enhance their programming skills. The adaptation of source code from one piece of software to use in other projects is common among programmers. This eases the programming process. This kind of adaptation is known as software re-usability. The Quality of Source Code: There is no such concept of a well-written source code in computer terminology. But, from a human programmer's perspective, source codes often stress on readability to reduce the cost of software source code maintenance. An affordable web development expert follows the source code programming style guides to ensure the programs are written with ease.
