The analyzer has detected a code fragment that may contain a logical error: operands of an operator are equivalent.
The example:
if (a != 0 && a != 0)In this case, the identical expressions a != 0 surround the && operator, which indicates an unintended error. Most likely, another variable should be checked:
if (a != 0 && b != 0)The second check may also be redundant.
The diagnostic rule also considers non-identical but equivalent expressions.
The example:
if ((a * b) > (b * a))The analyzer reports a warning because multiplication is commutative, and the expressions will evaluate to the same result.
You can look at examples of errors detected by the V7001 diagnostic. |
