Whether we can use like this?

//This exists /*char c='a'; switch(c) { case 'a': break; case 'b':break; }*/ //But this?? char *c="hi"; switch(c) { case "hi": break; case "hey": break; }

Unfortunately you cannot use switch clauses on strings nor char pointers in C++. Consider using if-else instead.
