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?

For what platform? You're going to have to write something platform specific to do this... — Jerry Coffin

@EboMike: Or perhaps he's using an environment that employs something other than a heap for the free store. The language doesn't care what it is. — Lightness Races in Orbit

Override the basic new operators and count the memory used. Voila, you got your mechanism ;) ... you can also use profilers with or without instrumentation to achieve the same. — 0xC0000022L
