About C language

C is a general – purpose programming language initially developed by Dennis Ritchie between 1969 and 1973 at AT&T Bell Labs. It was designed to be compiled using a relatively straightforward compiler, to provide low-level access to memory.

The C language consists of:

Constants

Variables

Keywords

The alphabets, digits and special symbols when properly combined form constants, variables and keywords. Later we discussed on it

In any C program we typically do lots of calculations the results of these calculations are stored in a computer’s memory. Like human memory, the computer’s memory also consists of millions of cells the calculated value are stored in a cells (also calls memory location).
