Why do I get a compiler warning for converting a string literal to a char*, is it bad?

Question

So the compiler tells me this is a deprecated conversion from a string-literal to char*:

 char* myString = \"i like declaring strings like this\";

Answer 1

It shouldn't even compile. If you need to pass it to function that you are sure won't change the string you need to use const cast, its one of its correct uses:

functionName(const_cast("something"));

Or if you don't want the const cast, you can copy the string to the stack:

char str[] = "something";
functionName(str);
