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:


              
123456

            
int b = 1;
int *pb = &b;

*pb = *pb + 2;  // b = 1 + 2
b = 3 + *pb;   // b = 3 + 3
cout << b << endl;
copy

In all the statements above, we added numbers to the value of b and assigned the result to the variable b.

question-icon

Decrease x by 3 using pointers.

int x = 1;
int *px = &x;

*px =;
