What is programming language?

A programming language is a set of instructions used to communicate to a computer. These instructions are written by programmers in English language to be feed to computer and computer process it to give output.

Note:

Syntax: Each programming language has its own rules and structure (syntax) that must be followed.

Semantics: The meaning of the commands written in the language.

Types:

 There are many types of programming languages, including:

High-level languages (e.g., Python, Java, C++) – easier for humans to read and write.

Low-level languages (e.g., Assembly, Machine code) – closer to the hardware, harder for humans to read and understand.

There are also Compiled, Interpreted programming languages based on its execution.

Compiled programming language: Programs are translated into machine code all at once (e.g., C++) by compiler and then execution happen on compiled code. Execution is faster.

Interpreted programming language: Programs are executed line by line by an interpreter (e.g., Python). Execution is slower.

Examples of Programming Languages:

Python – easy to learn, widely used in AI, web, automation.

JavaScript – used in web development.

Java – popular in enterprise software, Android apps.

C – foundational language, used in systems programming.

C++ – extension of C with object-oriented features.

In short, a programming language is a tool that allows humans to give instructions to computers in a structured and understandable way.
