Created By: Muhammad Waseem • A programming language is a set of commands, instructions, and other syntax use to create a software program. • Languages that programmers use to write code are called "high-level languages." • This code can be compiled into a "low-level language," which is recognized directly by the computer hardware.

Created By: Muhammad Waseem • Programming Languages are of two types: • Low Level Programming Language : Low-level languages include assembly and machine languages. • High Level Programming Language : High-level languages are designed to be easy to read and understand. Examples of high-level languages include C, C++, Java, Perl, and PHP.

Created By: Muhammad Waseem • C Is A High Level Programming Language Used To Create High Level Program. • It Is A General Purpose And Structured Programming. • Developed By Dennis Ritchie At AT & T Bell Laboratories In 1972 In USA. • It Is Also Called As Procedure Oriented Programming Language. • It Is So Popular Language Because It Is Reliable, Simple And Easy To Use.

Created By: Muhammad Waseem • C language is the most commonly used programming language. • It is used for writing operating systems. • UNIX was the first operating system written in C. • Later Microsoft Windows, Mac OSX, and GNU/Linux were all written in C. • Not only is C the language of operating systems, it is the precursor and inspiration for almost all of the most popular high-level languages available today. • In fact, Perl, PHP, Python and Ruby are all written in C.

This means that ‘C’ programs written from one computer can be run on another computer with no modification. A ‘C’ program is basically a collection of functions that are Created By: Muhammad Waseemsupported by the ‘C’ library.
