[Dev-C++] Manipulator

[Esteban V. <est...@ho...>]

Hi, which is the ostream manipulator to printf the direction of a varible ?
In C it can be obtained by the next sentence...

int var;
...
printf("%p", &var);

bye, Esteban

char* is more difficult, since there's a specific overload for it that 
prints a string. I suppose you could cast it to a long and print that. 
Bit ugly, though.

char * str;
cout << hex << reinterpret_cast<long>(str) << endl;

By the way, my earlier answer could be even simpler:

int var;
cout << &var << endl;   // still prints in hex.
