Iteration with the do while loop

The do while loop

The do while loop has the same features as the while loop. The do while loop works on a condition and can be used when we don’t know how many iterations we’ll need to make.

The difference from the while loop is that where a while loop might never execute because the condition could be false the first time we test it, the do while loop is guaranteed to run at least once. The reason for this is because the condition is moved from the beginning of the loop to the end of it.

This can be good for several reasons, and it can make our guessing game slightly less complicated.
