Heap

if you're using MSVC then new will return a NULL pointer if there was a problem with allocating the memory. Unless you have a very old computer allocating 200 thousand integers (400kb of memory) should not cause a problem.

So, should i use the heap memory anytime? Will heap memory has size limition?

Also, if i create a variable using heap memory in a class, is it mean the variable is gobal variable?

Thanks.

The limitation in size is how much memory you''ve got in your machine, minus what''s already used by other applications. Fire up the task manager to have a look at that.

Allocating memory on the heap does not change the scope of the pointer variable you use to access it. Remember to free it at some point though, or you''ll get a memory leak.
