Introduction

 

• C was developed by a system programmer Dennis Ritchie in 1972, at American Telegraph & Telecommunication (AT & T) Bell laboratories in New Jersey USA.
• C was also used to develop some parts of this operating system.
• C is generally supported by most compilers. 

C defined as the following ways,

1. Mother language
2. System programming language
3. Procedure-oriented programming language
4. Structured programming Language
5. Mid-level programming Language

1.Mother language

• C language is considered as the mother language of all modern programming languages because most of the compilers, JVMs, Kernals, etc. are written in C language.
• Most of the programming languages follow C Syntax.
• C provides the core concepts like array, strings, functions, file handling

2.System programming language

• System programming language is used to create system software.
• C language is a system programming language because it can be used to do low-level programming.
• It is generally used to create hardware devices, OS, drivers, kernals, etc.
• Linux kernel is written in C.
• C can't be used for internet programming.

3.Procedural language

• Procedure is known as a function, method, routine, subroutine, etc
• Procedural language specifies a series of steps for the program to solve a problem
• Procedural language breaks the program into functions, data structures, etc.

4.Structured programming language

• Structured programming language is a subset of the procedural language.
• Structure means to break a program into parts or blocks.
• In the C language, we break the program into parts using functions.
• It makes the program easier to understand and modify.

5.Mid-level programming language

• C is considered as a middle-level language
• It supports the feature of both low-level and high-level languages
• Low-level language:
• Low-level language is specific to one machine
• Machine dependent
• Not easy to understand

• High-level language:
• High-level language is not specific to one machine
• Machine independent
• Easy to understand
