Hi All,
The program given below compiles fine.
but if we use the statement ,
int x = MYSPACE::VALUE +1;
It gives an error. Why is it so ? (when the #define is present inside the
scope of the namespace ) ????
****************************************************************************
**
namespace MYSPACE{
#define VALUE 50;
};
int main(){
int x = VALUE + 1;
return 1;
}
Regards,
Megha

#define are managed by the preprocessor, which isn't aware of
namespaces.
use const instead :
const int VALUE = 50;

#define's are handled by the preprocessor, and like macros are unaffected
by namespaces, classes, etc.
If you try to use them, the compilersees:
>namespace MYSPACE{
>};
>int main(){
> int x = MYSPACE::50 + 1;
> return 1;
>}
which has not much sense...
If you need to use namespaces for constants, use enumes instead:
namespace MYSPACE{
enum {
VALUE = 50
};
};
int main(){
int x = MYSPACE::VALUE + 1;
return 1;
}
works.
