V3017. A pattern was detected: A || (A && ...). The expression is excessive or contains a logical error.

Dec 14 2015

The analyzer has detected an expression that can be reduced. Such redundancy may be a sign of a logical error.

Consider this example:

bool firstCond, secondCod, thirdCond;
....
if (firstCond || (firstCond && thirdCond))
....

This expression is redundant. If 'firstCond == true', the condition will always be true regardless of what value the 'thirdCond' variable refers to; and if 'firstCond == false', the condition will always be false – again, irrespective of the 'thirdCond' variable.

Perhaps the programmer made a mistake and wrote a wrong variable in the second subexpression. Then the correct version of this code should look like this:

if (firstCond || (secondCod && thirdCond))

You can look at examples of errors detected by the V3017 diagnostic.
