*MSC00-EX1:* Compilers can produce diagnostic messages for correct code. This is permitted by C99 \[[ISO/IEC 9899-1999|AA. C References#ISO/IEC 9899-1999]\], which allows a compiler to produce a diagnostic for any reason. It is usually preferable to rewrite code to eliminate compiler warnings, but if the code is correct it is sufficient to provide a comment explaining why the warning message does not apply. Some compilers provide ways to suppress warnings, forsuch example,as suitably- formatted comments or pragmas, which can be used sparingly when the programmer understands the implications of the warning but has good reason to use the flagged construct anyway. |
Do not simply quiet warnings , for example, by adding typecasts or other means. Instead, understand the reason for the warning and consider a better approach, for example, use such as using matching types and avoid typecasts avoiding type casts whenever possible.
