How to simulate printf's %p format when using std::cout?

Question

unsigned char *teta = ....;
...
printf(\"data at %p\\n\", teta); // prints 0xXXXXXXXX

How can I print variable address using iostreams

Answer 1

Depending on wheter or not you want to use more formatting options printf gives, you could consider using sprintf

By it, you could format a string just like you'd do with printf, and afterwards print it out with std::cout

However, this would involve using a temporary char array so the choice depends.

An example:

unsigned char *teta = ....;
...
char formatted[ 256 ]; //Caution with the length, there is risk of a buffer overflow
sprintf( formatted, "data at %p\n", teta );
std::cout << formatted;
