But it has a few quirks, one of which is that the pointer references memory in a different way than had you allocated it yourself. It's best to use this string without modification, which can lead to trouble in other functions elsewhere in the code. So one solution is to make the string a constant. As a constant, the string can't be modified, which is okay for a string literal. The best solution, however, is to use a ray notation to reference such a string literal. You could make this declaration a constant as well, though the big difference is that the string is accessible elsewhere within your code, just in case you plan on doing something with it. To…
