⟩ What is const pointer?

const pointer is a pointer which you don’t want to be pointed to a different value. That is, the location stored in the pointer can not change. We can not change where the pointer points. It is declared as:

type * const name

type is data type

name is name of the pointer

eg: char * const p

Since the location to which a const pointer points to can not be changed, the following code:

char ch1 = ‘A’;

char ch2 = ‘B’;

char * const p = &ch1;

p = &ch2;

will throw an error since address stored in p can not be changed.
