What is the difference between these (bCondition == NULL) and (NULL==bCondition)?
Why do some people write instead of:
if(someVar == 0) {}
this:
if(0 == someVar) {}
What is the difference ?
Thanks.
Just a good practice. If by mistake, you use single
=instead of==, finding the bug in the first one is very difficult but the second one would fail to compile clearly showing the line of error.
