Chapter 21 Break and Continue

Break and Continue give you ways to bypass instructions in a loop

When break is encountered the program skips to the end of the loop and regards the loops as finished

 

Exercise: copy your Week 10 X-maker program code to a new project and modify it with break so that it only prints a maximum of 10 Xs

Example output

Making Xs!


How many Xs do you want? 6

XXXXXX

How many Xs do you want? 2

XX

How many Xs do you want? 25

XXXXXXXXXX

How many Xs do you want? 57

XXXXXXXXXX

How many Xs do you want? 0


I'm done!

 

 

When continue is encountered, execution skips to the end of the loop, but then returns to the start of the loop and continues iterating the loop as before.

Exercise: Write a program that prints out a range of numbers and after each one prints "is not a multiple of 3"... unless the number IS a multiple of 3, for which it prints nothing after the number. Use continue to skip the that message.

Hint: This program probably makes some use of the modulo operation (%).

sample output:

Multiple of Three?

1 is not a multiple of 3.
2 is not a multiple of 3.
3
4 is not a multiple of 3.
5 is not a multiple of 3.
6
7 is not a multiple of 3.
8 is not a multiple of 3.
9
10 is not a multiple of 3.
11 is not a multiple of 3.
12
13 is not a multiple of 3.
14 is not a multiple of 3.
15
16 is not a multiple of 3.
17 is not a multiple of 3.
18
19 is not a multiple of 3.
