Determine memory consumption

Question

In C++, with this:

std::time_t first  = time(NULL);
/* .. code .. */
std::time_t second = time(NULL);

std::cout << "Seg : " << difftime(second,first) << std::endl; 

I can determine my program's execution duration.

Can I determine its memory consumption at different points through the program?

Not easily.
