Chapter 6, Problem 1CRP

Program Plan Intro

Programming language:

A language that allows algorithms to be understood easily by humans and can be converted into the instructions which can be read by the machine easily is a programming language. The language used by the programmer is a high level language, and the language which is recognized by the computer is a low level language.

Explanation of Solution

Programming language is machine independent:

The language runs on its own and doesn’t require any machine. It requires only appropriate compiler and an interpreter.

The source code of programming language runs without any changes in various platforms. Examples of programming language are java and python.

The high level language is not the language of machine, it only responds in bits $0$ and $1$. So, a high level language is converted to a low level machine language with the help of compilers and interpreters.

Some language such as $C++$, java have a source code that needs to be compiled before running and are called as compiled languages and for languages like PHP, the source code can run through interpreter without being compiled and these languages are called interpreted languages. These languages do not depend on machine to run.
