When should you use break or continue in a loop?
|
||
|
|
When it makes your code easier to read/maintain/understand as opposed to working it into the boolean condition for the loop.
|
||
|
|
The danger of using break or continue in a large loop is that it becomes 'hidden' and people might not realize that something inside the loop affects its control flow.

What are the advantages/disadvantages of switch...case?
|
||
|
|
+ The expression is only checked once in one place, and would only need to changed in one place
|
||
|
|
- You have to keep putting 'break;' at the end of each case if you don't want the case to "fall through". If you forget, it still compiles.
|
||
|
|
+ You can exploit the fall-through behavior, as follows:
|
||
|
|
for(int days = 1; days <= 12; days++) {
|
||
|
|
switch (days) {
|
||
|
|
case 12: ...three french hens...
|
||
|
|
...
|
||
|
|
case 3: ...three french hens...
|
||
|
|
case 2: ...two turtle doves...
|
||
|
|
case 1: ...partridge in a pear tree...
|
||
|
|
}
|
||
|
|
}
