Exit Statement

The EXIT statement quits the processing of the current loop. If we use EXIT outside of the loop then it leaves the current processing block. Hence no other statement of that processing block will be executed. It is recommended that EXIT needs to be used inside a loop. We can use it outside of loop as per requirement as well.

If there are nested loops and we use EXIT statement in the inner loop then the system will leave the inner loop after executing the EXIT statement. The program control will continue with the outer loop execution.

Here the first set of output has come without the exit statement. Second set has come by exit statement. Whenever the program controller finds the item Rice then it executes exit. The system leaves the loop totally. That is why only one output has come yet..
