c pointer stack heap
Does C use stack or heap?
In practice this is almost invariably a stack.
But it does not require a heap.
A heap is only normally required if you use library functions like malloc ; not by the C language itself.
There is actually nothing magic about a heap - you can write malloc and free in pure C.Can pointers point to stack?
In C/C++, pointers can point to either the stack or the heap, depending on where the memory being pointed to is allocated.
If the memory is allocated on the stack, such as when a variable is declared within a function, then the pointer will point to the stack.28 juil. 2016
