|This rule is Obsolete|
|Synopsis:||Do use spaces before and after binary operators for readability|
For best readability code as follows:
int c = (a - b);
Clearly this even is more apparent when 'a' and 'b' become more elaborate/complex expressions ... as in real code.
To continu the simple examples, the following is also OK, although less OK for more complex expressions:
int c = a - b;
Finally prevent unclear code like (especially for complexer expressions):
int c = a-b;
