# V8010\. Two or more 'case' branches have equivalent expressions\.

The analyzer detected identical expressions in case\. This error may occur as a result of copy\-pasted code\. As a result, not all of the intended options may be handled in the switch statement, and some branches may become unreachable\.

The example:

```cpp
const (
    MONDAY    = 1
    TUESDAY   = 2
    WEDNESDAY = 3
    THURSDAY  = 4
    FRIDAY    = 5
)

switch {
case day == MONDAY:
  ....  
case day == TUESDAY:
  ....
case day == WEDNESDAY:
  ....
case day == THURSDAY:
  ....
case day == MONDAY:
  ....
}
```

In this example, the `day == MONDAY` condition is used twice\. Consequently, the code inside the last `case` will be unreachable\. Instead of the second identical expression, the `day == FRIDAY` is intended to be used\.

The fixed code:

```cpp
switch {
case day == MONDAY:
  ....  
case day == TUESDAY:
  ....
case day == WEDNESDAY:
  ....
case day == THURSDAY:
  ....
case day == FRIDAY:
  ....
}
```
