V3030. Recurring check. This condition was already verified in previous line.
The analyzer has detected a possible error that has to do with one and the same condition being checked twice.
Consider the following two examples:
// Example N1:
if (A == B)
{
if (A == B)
....
}
// Example N2:
if (A == B) {
} else {
if (A == B)
....
}The second "if (A == B)" condition is always true in the first case and always false in the second.
This code is very likely to contain an error – for example a wrong variable name is used because of a typo. Correct versions of the examples above should look like this:
// Example N1:
if (A == B)
{
if (A == C)
....
}
// Example N2:
if (A == B) {
} else {
if (A == C)
....
}This diagnostic is classified as:
