HOW TO USE CONST QUALIFIER WITH POINTERS

• const qualifier – variable cannot be changed

–Good idea to have const if function does not need to change a variable.
–Attempting to change a const is a compiler error.

• const pointers – point to same memory location

-Must be initialized when declared.
int *const myPtr = &x;

• Type int *const – constant pointer to an int

const int *myPtr = &x;

• Regular pointer to a const int

const int *const Ptr = &x;

• const pointer to a const int
• x can be changed, but not *Ptr
