Use addresses of dynamically declared objects?

I'm told I should initialize pointers to the address of the item.
i.e. char *mypoin = &someotherchar;

I've never seen the &operator used in examples of dynamiccally allocated objects. Do I need to put it there? If I don't, is it automatically set to the address?

>>char *mypoin = &someotherchar;

If someotherchar exists on the stack, you use the & operand to get the memory address of the variable and then initialise it to the pointer as above

If someotherchar was itself a pointer to a variable, then you would not use the & operand, you would just "char *mypoin = someotherchar;" This would set mypoin to point to the same memory address as someotherchar

Code:

---

int x = 10,         
*ptrx = &x, //note use of '&'
*ptrFS = ptrx; // '&' not used

cout << *ptrFS;

---

This outputs 10 which was the origonal value of x

When an object is dynamically created using new or alloc a pointer is returned. Since it is a pointer, you do not need the & to get the address of the actual data, the return pointer is the address of the actual data.
