const char pointer assignments

Question

Are the following assignments valid? Or will any of these create problems. Please suggest.

const char * c1;  
const char * c2; 
const char * c3;
char * c4;

         


        

Answer 1

These assignments are all perfectly valid as I and others have explained in your recent run of near identical questions.

A const char* is a pointer to memory that cannot be modified using that pointer. Nothing here can circumvent that. The compiler would object if you assigned c4 = c1 since then that would circumvent the const.
