C is a structured programming language developed by Dennis Ritchie in 1973 at Bell Laboratories. It is one of the most popular computer languages today because of its structure, high-level abstraction, and machine-independent feature. C language was developed with UNIX operating system, so it is strongly associated with UNIX, which is one of the most popular network operating systems in use today and the heart of the internet data superhighway.
Now, it had become a widely used professional language because of the following reasons.
E.g.:- If, else, while, const, break….
Keywords=32, operators=44, separators=14.
E.g.: +,*,&,%.
By using separators, we can separate individual units ‘ called taken.
In ‘C’ programming language no. of separators are ‘14’.
E.g.:, . ; ‘“{space.

It is a fixed one never be changed during the execution of the program.
Constants are classified into two types. i.e.
By using alphanumeric constants we can represent alphabets and numeric values. Alphanumeric constants are a combination of 52 alphabets, 44 operators, 14 separators,
0-9 numeric values and some spiral kind of symbols.
E.g.: ‘A’, ‘d’, ‘@’,’*’,’5’
By using numeric constants, we can represent value type data.
E.g.:- 12, 16,-851,-47,-32765.
The foot will represent the values with functional parts.
Eg: 12.35, 16.89,-78.95….
Char, Int & Float are called basic data types (or) basic data.
Note: elements, because any data is a combination of these 3 types of constants only.
The implementation part of the f’n is already available along with the compiler.
As a programmer, whenever we need to perform any specific task that simply called predefined f’n.
Eg: printf(), scanf(), clrscr(), getch(), sleep(), delay(), atoi(), ecut(),fcut(),get data(),settime(),exit()
The grammar of a specific programming language is called syntax.
The basic syntax of the ‘C’ Language is every statement should end with ‘;’
