Re: [algogeeks] Re: Differentiate the following declarations.
*const char* a* is *equivalent* to *char const * a* A simple method which most people use in coding is that const is written after the value which needs to be constant. So, *char const *a* means a is a pointer that points to a character which is a constant i.e you can not change the value which a points to, however you can change values for a i.e different addresses can be applied to a. and *char *const a* means a is a constant pointer to character i.e you can change the values pointed by a, however you can not change the values i a i.e once a is assigned an address, a can not be changed. -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

[algogeeks] Re: Differentiate the following declarations.
Using Spiral-Anderson rule, 1:- const char * a - a is a pointer to char const (character which is constant , the value pointed by the pointer is constant) 2:- char * const a - a is a const pointer to char (pointer is constant, it always point to same memory location) 3:- char const * a - a is a pointer to const char (again character is constant , the value pointed by the pointer is constant) *a='F' a =Hi From above 1 2 3 *a= 'F' Legal Illegal Legal a=Hi Illegal Legal Illegal -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.
