Address Operator & Pointer

Address Operator : it shows where in the memory the variable is stored

#include <iostream>

int main()

{

using namespace std;

int f = 10;    //make variables

int e = 2;

//output on the screen?

cout<< f << endl;

cout<< &f <<endl;         //address where the variable is located in the memory(HexDecimal location)

cout<< e <<endl;

cout << &e <<endl;

system("pause");

return 0;

}

===> useful for pointer

Pointer : variable that holds an address of your memory 

int main()

{

int f = 10;

int e = 2;

//pointer and stored var should have same type

int *pointer;    //what address??

//have to answer it..

pointer = $f;

cout<<pointer<<endl;        //address of memory(point the space of your memory where the f is..)

return 0;
