Difference between the pointer to constant and constant pointer:

Pointer to constant Constant pointer

Pointer to constants can be used in a situation when an address of a constant item is passed to a pointer such that no modification can be made to those variables. Value that a constant pointer holds can be changed, whereas the address the pointer variable holds cannot be changed is called as a constant pointer.

Example:

//definition of pointer to constant variable

const int *ptr;

Explanation:

In the above definition, the variable “ptr” is declared as constant and any change made will not be accepted by the compiler...
