Question

I still dont get what pointer and address mean?
Can someone explane me what it mean in a simple english and an example?

Answer 1

int* p; // p is pointer
int q = 1; // q is variable

cout << &q; // output address of q.

p = &q; // put the address of q inside pointer p.

cout << p; // still output address of q.

cout << *p;

// outputs "point-to" p, which points to address of q
// outputs 1
