A pointer to a const value (sometimes called a pointer to const for short) is a (non-const) pointer that points to a constant value. In constant pointers, the pointer points to a fixed memory location, and the value at that location can be changed because it is a variable, but the pointer will always point to the same location because it is made constant here. Let us consider the code snippet to understand how pointer to constant works. This means they cannot change the value of the variable whose address they are holding.
