How to know the memory usage in C++

Question

I have a C++ program running by Visual Studio 2010, how can i monitor the the memory usage of my program? Does there exist simple API, such as i can call clock_t start1 and start1 = clock(); to monitor the time usage of my program. Thanks:)

Solution

Memory management is not an easy problem like timing, and it is definitely more complicated to track.

These should help you solve whatever your specific memory-related problem is, whether it's looking for memory leaks, overwriting the end of an allocated buffer, or simply tracking how much memory you've allocated.
