Answer 4

If you need a place to store some data, malloc is your friend. You can (M)emory (Alloc)ate some RAM to use to store it. If your program ends, or you (dealloc)ate it, then it's gone.

Answer 5

Malloc is a function in some programming languages (most notably C) that allocates a certain number of bytes to hold some data structure?

Answer 6

What do you mean by an appropriate answer..?

Answer 7

WEll, malloc is the c equivalent of new. With m alloc you can allocate a chunk of memory at runtime and since it's allocated at runtime it's obviously stored in a heap.

So you can do something like take input from user and create an array of that size

int * k = malloc(sizeof(int[n]);

It returns a pointer to the memory location and you have to free the memory before the program ends.

Answer 8

I would consider new to be a wrapper of malloc.
