Global and static pointers

Global and static pointers are initialized to NULL when the program starts. It is shown in the example below:

int	*globalptr;

void	ft_function()
{
	static int	*staticptr;
	...
}

int	main(void)
{
	...
}

Static and global variables are often place in a data segment that is separate from the data segment used by the stack and heap.
