Whats the diffrents between pointers and pointing too please?

i know java dosent support pointers but i dont really know what it is as i havent done c++ i know java still points to things tho like methods

Answer 1

Pointers are variables that store the memory addresses of other variables. Pointing is the act of storing (pointing to) an address within the pointer. ex:

int x =0;
int *p; —> pointer p
p=&x; —> pointing at address of x
cout << p << endl; —> prints x’s address
cout << *p; —> prints x

& is dereferencing operator; when used in conjunction with a pointer think ‘address of’. The example is from c++, this concept is one of the reasons that c and c++ are so powerful.
