bookDeeping into Pointers

Let’s return to the previous code:

Here the variable pb is a pointer. It contains the address to the variable b. Use the pointer without an asterisk to output the address the pointer contains and with an asterisk to get the value of the variable by address:


              
12

            
cout << pb << endl;  // address of the variable b
cout << *pb << endl; // the value of the b
copy

The pointer always points to the address of the declared variable, and if the value of the variable changes, the address doesn’t:


              
1234567

            
int b = 2;

int *pb = &b;
cout << *pb << endl;

b = 1;
cout << *pb << endl
copy
