Constant pointers and pointers to constants

3 Scenarios related to the const, pointer, and object pointed to by the pointer:

1. Pointers to constant objects

2. Constant pointer to an object

3. Constant pointers to constant objects

In the first case, we cannot modify the object being pointed to, but we can point the pointer to another object:

Const char* pstring ("Some text");

In the second case, we cannot modify the address stored in the pointer, but you can modify the object that the pointer points to:

char* Const pstring ("Some text");

In the last case, both the pointer and the object being pointed to are defined as constants and therefore cannot be modified:

Const char* Const pstring ("Some text");
