Whether we can use like this?

Question

//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;
}

Answer 1

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