A keyword is a word or identifier that has a particular meaning to its programming language.
A keyword is a reserved word. It cannot be used as the name of a variable or subroutine.
The meaning of a particular keyword differs from language to language.
A modifier keyword, or modifier, is a keyword that modifies an entity.
For example, the C++ type long int is an integer modified by the modifier keyword long to increase its range.
In C++ the standard reserved keywords are:
asm,
auto,
bool,
break,
case,
catch,
char,
class,
const,
const_cast,
continue,
default,
delete,
do,
double,
dynamic_cast,
else,
enum,
explicit,
export,
extern,
false,
float,
for,
friend,
goto,
if,
inline,
int,
long,
mutable,
namespace,
new,
operator,
private,
protected,
public,
register,
reinterpret_cast,
return,
short,
signed,
sizeof,
static,
static_cast,
struct,
switch,
template,
this,
throw,
true,
try,
typedef,
typeid,
typename,
union,
unsigned,
using,
virtual,
void,
volatile,
wchar_t,
while
The following are alternative representations for
operators and thus reserved
keywords under some circumstances:
and,
and_eq,
bitand,
bitor,
compl,
not,
not_eq,
or,
or_eq,
xor,
xor_eq
Individual C++ compilers may also include additional specific reserved keywords.
In Java the standard reserved keywords are:
abstract,
assert,
boolean,
break,
byte,
case,
catch,
char,
class,
const,
continue,
default,
do,
double,
else,
enum,
extends,
final,
finally,
float,
for,
goto,
if,
implements,
import,
instanceof,
int,
interface,
long,
native,
new,
package,
private,
protected,
public,
return,
short,
static,
strictfp,
super,
switch,
synchronized,
this,
throw,
throws,
transient,
try,
void,
volatile,
while
The following are
literals and thus
reserved keywords:
true,
false,
null
