How you can do that is usually platform-specific and can be
complicated (e.g., on some platforms there isn't a nice number you can
look at and say "there, that's how much memory it uses!").

Your best option is probably to use a memory profiler such as the
Massif heap profiler that comes with Valgrind or the one in Apple's
development tools. A newsgroup or discussion forum specific to
development for your operating environment would be the appropriate
place to seek more information on the subject.

Couldn't you do that just by looking at Processes in the Task Manager?

What you care about is probably RSS or RES, the "resident set size."

Create your own global new and delete operators and keep track your self.

I dont know what the difference between them, actually i wanna know
can i insert some code to my program and when it
ends it will show the sum of used memory

Not without some help from a separate profiling tool. Check out
valgrind (pronounced "Val grinned").
