about STL main memory release

[nanger]

if I 'new' something,I need to 'delete' it when it becomes of no use in order to
release main memory.
when it comes to STL container, should I do the deleting mannually?
or to the point,
can STL container automatically release the main memory allocated to it or not?

thank u!

Could you give an example of what you're asking?

Good thing I understand nub. I think he means that if we do something like this:

#include <fstream>

int main(int argc, char ** argv)
{
	//allocate memory on heap for new ofstream.
	std::ofstream * bob = new std::ofstream;
	
	//This will not delete itself. If you leave it, it will cause a memory leak. Therefore..
	delete bob;
}

Same applies for containers. Sorry I couldn't give one for an actual container. But after this, I realized I've never used a pointer to a templated class or object and I actually don't know how. lol
