psat stejne veci stejne. Tj. kdyz prirazuji do unsigned, tak musim

dobry odkaz, ktery tvrdi, ze jen 9 tech pravidel ma pozitivni
korelaci s opravdovymi chybami a pres 20 negativni. Navic, pri
kazde uprave kodu muze dojit (dochazi) k chybam. Takze po
zmisrovani muze byt kod horsi nez pred ;-)<br>

<p class="MsoNormal">Rule 10.1 addresses a different issue. It
demands, among other things, that an expression which is
assigned to an unsigned variable should itself be unsigned.
This means that any constant or constant expression should
itself be of "unsigned" type - including the constant '0'.
The rationale behind this is that it is helpful to maintain
consistent signedness when constructing arithmetic
expressions, even if the omission of a 'U' suffix makes no
difference to the result.<o:p></o:p></p>
