defaultcasechecker

defaultcasechecker is a program for checking switch statement whether having default case.

Go does not provide exhaustive checks for switch statements. However, switch statements should always have a default case that either returns an appropriate error or performs some action. Therefore, this program identifies parts of switch statements that lack a default case.
