Pointer to int. C++

Question

I need to pass to function pointer to int. Now if I want to pass 5 I'm doing it like this:

int * i = NULL;
int b = 5;
i = &b;

Is there any better way to write it shorter?

I want to pass bytes that are in i int to this function:

void Write2Asm(void* pxAddress, BYTE * MyBytes,  int size)

Solution 1

You can just pass &b to the function; no need for an intermediate pointer variable.

Solution 2

Why to create a pointer variable?. Why can't you do it like this?.

int b = 5;
func(&b)

Solution 3

void f(int *i)
{
  //...
}

int b = 5;
f(&b);

is enough!
