Understanding recursion [closed]

Answer 1

To understand recursion, all you have to do is look on the label of your shampoo bottle:

function repeat()
{
   rinse();
   lather();
   repeat();
}

The problem with this is that there is no termination condition, and the recursion will repeat indefinitely, or until you run out of shampoo or hot water (external termination conditions, similar to blowing your stack).
