language:int denom = 0;if (denom != 0 && num / denom) { ... // ensures that calculating num/denom never results in divide-by-zero error }

Consider the following example:int a = 0;if (a != 0 && myfunc(b)) { doSomething();}

In this example, short-circuit evaluation guarantees that myfunc(b) is never called. This is because a != 0 evaluates to false. This feature permits two useful programming constructs.
