C expert programming-const pointer assignment

/// From expert C Programming # include <iostream> using namespace STD; void main () {char * CP; const char * CCP; CCP = CP; // compilation passed // CP = CCP; // compilation error // both operands are pointer to a compatible type with or without a qualifier, // The type pointed to by the Left pointer must have all the qualifiers of the type pointed to by the right pointer. Char ** CPP; const char ** CCPP; CCPP = CPP; // compilation error CPP = CCPP; // compilation error // although they are actually pointer types without delimiters // they are incompatible with the content pointed to by the pointers}
