Dereferencing
To operate with the variable, you can also access it by dereferencing the variable's pointer. For example, you can change the value of the variable by using pointers:
123456int b = 1; int *pb = &b; *pb = *pb + 2; // b = 1 + 2 b = 3 + *pb; // b = 3 + 3 cout << b << endl;
In all the statements above, we added numbers to the value of b and assigned the result to the variable b.
