this question has answer here: what difference between if (null == pointer) vs if (pointer == null)? 5 answers i have question in mind. in many places saw int a=2; if(2==a){ //some operation } can tell me advantage on comparing 2==a in place of a==2 . some people force error, rather incorrect behaviour, if accidentally typed = instead of == . however: it helps in circumstances (when 1 of values compared modifiable , other isn't) any decent compiler give warning if make mistake (add parentheses and/or explicit comparison if want assignment) so real purpose make code confusing read. a better habit might declare variables const , unless want them mutable. prevent accidental assignment, while making code easier rather harder reason about.
