Features of C-language

1. It is a structure oriented language  It means it fallows set of rules.
2. It is a portable language.
3. It is a case sensitive language. It treats lower and upper case separately.
4. It performs complex programs with high speed.
5. We can divide into Functions during the program execution.

History of C-language

C programming language was developed in 1972 by Dennis Ritchie at bell laboratories of AT&T (American Telephone & Telegraph), located in U.S.A.

Dennis Ritchie is known as the founder of c language.

It was developed to overcome the problems of previous languages such as B, BCPL etc.

Initially, C language was developed to be used in UNIX operating system. It inherits many features of previous languages such as B and BCPL.

Types of Middle level languages

It is also classified into Three types. Those are

1. Structured Oriented Programming Language

2. Object Oriented Programming language

3. Data Base programming language.

1. Structured Oriented Programming language :-

A Structure is a nothing but a rule. 

In this language we can fallow so many rules to implement the new software or new package.

Ex:-  C, Basic, Cobal,etc....

2. Object Oriented Programming Language :-

An object is nothing but a peace of a program. 

Every program executes with the help of object.

It is extension of Structured programming language. 

Ex:-  C++, Java,etc...

3. Data Base Programming Language :-

It is used to store the information into the computer permanently. 

It is also called Data Base Application.

Ex:-  Ms-Access, VB,Oracle,SQl,etc.

Introduction of Languages

It is media to provide communication between the objects for solving particular problem.

Every package develop with the help of language. 

This language is also classified into Three categories.Those are

1. Low level language

2. Middle level language

3. High level language

1. Low level language :-

In this language we can use Binary codes. i.e; 0's & 1's.

Machine knows only this language so it is called machine level language.

2. Middle level language :-

In this language we can use some mnemonic codes such as add,sub,mul,div.....etc

It is also called as a Assembly language.

Ex:- COBOL

3. High level language :-

In this language we can use some mathematical notations such as +,-,/,*,etc........

It is also called as a User friendly language language.

Ex:- C,C++,JAVA,etc.
