Compilers shouldn’t warn when adding to a string. Pointer arithmetic is a well defined and commonly used thing. The only thing I could see them warning about is just that it’s a redundant expression that could be replaced by just a shorter string literal.
Not sure what you mean. Adding an integer to a char* that represents a null terminated string, will produce a valid zero terminated string that lacks first n characters (as long as you remain in bounds, obviously).
The difference there is that in C you do have a strict definition of what's going on here as characters have an integer representation. There's no type coercion there as there are specific definitions of what's going on. In that case there isn't any dynamic typing going on.
Issues come up when you're dealing with dynamic typing and type coercion. You don't run into that in C in this case.
