Break statements are used to exit the switch block. It's not that a "jump" statement (by which I assume you mean break, continue, goto, return or throw) has to be at the end, it's that a statement with an unreachable end point has to be at the end. The break statement isgenerally written along with a condition. There is no need of use of break in else-if ladder. It provides an easy way to dispatch execution to different parts of code based on the value of the expression. If none of the case labels matches to the value of the expression and the default group is not present, then no action will be taken by the switch statement and control will be transferred out of the switch statement. . Series 1 -4 7 -10 . The switch statement can have many conditions. Log in, to leave a comment.
