Introduction To Programming Language

What is a  Programming Language?

A programming language is a set of commands, instructions use to create a software program. 

Languages that programmers use to write code are called High-level language.

Code can be compiled into a Low-level language which is recognized directly by the computer.

High-level languages:

High-level languages are designed to be easy to read and understand. This allows programmers to write source code in there own way. Using logical words and symbols. 

For example,

keywords like if, else , while ... etc are used in most major programming languages. Symbols like <, >, ==, and != are common operators. 

Many high-level languages are similar enough that programmers can easily understand source code written in multiple languages.

Many types of high-level language exist and are in common use today, including:

• Python
• C++
• Java
• C#
• JavaScript

Languages like C++ and Java are called "compiled languages" since the source code must first be compiled in order to run. Generally, compiled languages are used to create software applications.

Languages like Python and R are called "interpreted languages" since the source code can be run through an interpreter without being compiled. Generally, interpreted languages are used for running scripts, such as those used to generate content for dynamic websites.

Low-level languages:

Low-level languages include assembly and machine languages. It is more difficult than high level language to understand and write the code. The machine code or machine language contains a series of binary codes that are understood directly by a computer's CPU.
