Internal C++ pointer/array management

Hi there! When I was coding some things, a question came up. How does C++ remember the size of an array located on the heap? Like this: int* pInts = new int[100]; Then I want to delete them with delete [] pInts; Okay, in this example, the compiler might easily "remember" how many ints to delete since "100" is a constant, but what if it''s a variable like: int sz = 100; int* pInts = new int[sz]; delete [] pInts; Does the compiler generate a size variable somewhere to remember how many ints I''ve allocated or what? ---------------------------------------------- Petter Nordlander "There are only 10 kinds of people in the world.
