Character set

C Keywords
Keywords are predefined, reserved words used in programming that have special meanings to the compiler. Keywords are part of the syntax and they cannot be used as an identifier. For example:
int money;
Here, int is a keyword that indicates money is a variable of type int (integer).
As C is a case sensitive language, all keywords must be written in lowercase. Here is a list of all keywords allowed in ANSI C.
C Keywords
auto double int struct
break else 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 unsigned
All these keywords, their syntax, and application will be discussed in their respective topics. However, if you want a brief overview of these keywords without going further, visit List of all keywords in C programming.
C Identifiers
Identifier refers to name given to entities such as variables, functions, structures etc.
Identifiers must be unique. They are created to give a unique name to an entity to identify it during the execution of the program. For example:
int money;
double accountBalance;
Here, money and accountBalance are identifiers.
Also remember, identifier names must be different from keywords. You cannot use int as an identifier because int is a keyword.
