C programming keywords

In this chapter you will learn about keywords. In C programming, the keyword is reserved (reserved) which is part of syntax.

C token
The smallest unit of C programming language is called token. There are three types of tokens in C programming and these tokens are used in all programs

Keywords

Constant
Character set
The combination of alphabets, numbers and special characters used in C programs are letter sets.

Alphabets

Lowercase (lowercase): a b c ...................................... x y z

Digits
0 1 2 3 4 5 6 7 8 9

C. Keyword (Keyword)
Keywords in programming are predefined and reserved words that carry special meaning. Being part of the keyword syntax, they can not be used as identifiers. For example:

int age;
Here int is the keyword that tells 'age' to be the integer type variable.

Because C is a programming case-sensitive, all keywords must be typed in lowercase. Here is the list of all the supported Ansi (ANSI) supported keywords

C Keywords
auto double int struct
break further long switch
case enum register typedef
char extern return union
continue for signed void
do if static while
default goto sizeof volatile
const float short uncigned
Based on the compiler without these keywords, C programming language supports some more keywords.

These keywords, their syntax and their usage are discussed in related topics. However, if you want to take the idea of these keywords without being able to jump in front of you, then you can visit all the keyword list pages in C programming.
