What is keywords ?

C language has some words that have the fixed meaning. The meaning of the words can not be changed in the programs; these fixed meaning words are called keywords.
The all C language keywords are written in small letters (lower case). The keywords cannot be used as variable names because if we do so we are trying to assign a new meaning to the keyword, which is not allowed by the compiler. C language supports 32 keywords are as follows:

auto
break
case
char
const
continue
default
do
double
else
enum
extern
float
for
goto
if
int
long
register
return
short
signed
sizeof
static
struct
switch
typedef
union
unsigned
void
volatile
while
