Keywords in C-Language

Every 'C' word is classified as either a keyword or an identifier. All keywords have field meaning & these mean's can't be changed.

Standard ANSI 'C' recognizes the following 32 keywords are:

1.	auto	Defines a local variable as having a local lifetime.
2.	break	Passes control out of the compound statement.
3.	const	Makes variable value or pointer parameter un modifiable.
4.	continue	Passes control to the beginning of the loop.
5.	do	Do-while loop
6.	enum	Defines a set of constants of type int.
7.	extern	Indicates that an identifier is defined elsewhere
8.	float	Floating point data types.
9.	double	Floating point data types.
10.	for	For loop
11.	Go to	Unconditionally transfer control.
12.	if	Conditional statement
13.	else	Conditional statement
14.	int	Basic data type (integer).
15.	char	Basic data types (character).
16.	register	Tells the compiler to store the variable being declared in a CPU register.
17.	return	Exits the function.
18.	short	Type modifiers.
19.	long	Type modifiers.
20.	signed	Type modifiers
21.	unsigned	Type modifiers.
22.	Size of	Returns the size of the expression or type.
23.	static	Preserves variable value to survive after its scope ends.
24.	struct	Groups variables into a single record.
25.	switch	Branches control
26.	case	Branches control
27.	default	Branches control
28.	Type def	Creates a new type.
29.	union	Groups variables which share the same storage space.
