Using pointers for the format specifier strings in printf-style functions can create potential security problems, as the number of arguments to be parsed could vary from call to call. Most compilers consequently warn about those: "format not a string literal and no format arguments [-Wformat-security]"
If we only want to print a constant string, we can just use a fixed "%s" format instead, and pass the string as an argument.
