This has nothing to do with inttypes.h, so it would have been helpful to change the subject line for this new topic. Your code has undefined behaviour. The compiler cannot detect all forms of undefined behaviour at compile time. > We provided -Wall and -Wextra. Please let me know the right flag to show the warning during compilation time. There is no option that will give you a warning for this code at compile time, sorry.
