are pointers on the stack or heap

PDF	Pointers Stack & Heap Memory malloc( ) Pointers in C allow you to change values passed as arguments to functions to work with memory that has been dynamically allocated and to more efficiently work

Memory in a C/C++/Java program can either be allocated on a stack or a heap.
Prerequisite: Memory layout of C program.
Stack Allocation: The allocation happens on contiguous blocks of memory.
We call it a stack memory allocation because the allocation happens in the function call stack.

Are double pointers stored on stack or heap?

If you declare a pointer as a local variable inside a function the pointer will be located on the stack._{29 oct. 2017}

Is malloc a stack or heap?

malloc allocates memory to the heap to the program for it's use, free releases the memory from use back to the heap (and can be reused by a future call to malloc )

What is a pointer to the heap memory?

The heap block pointers are sometimes known as "base address" pointers since by convention they point to the base (lowest address byte) of the block.
In this example, the three blocks have been allocated contiguously starting at the bottom of the heap, and each block is 1024 bytes in size as requested.

We use pointers basically for accessing the heap memory as any thing we use we are using it in the stack memory as eg like (int x) its stored its stored in the stack memory. To access anything the heap memory we use pointers. Heap memory is created at the time of run time.
