do-while loop (Glossary Entry)

This is a C programming technique for repeating a block of code while some condition is met.

The syntax is as follows:

do {
	// Loop body
} while (<condition to reenter the loop>)

Graphically, we can represented this as follows:

Note:

The loop body is always executed at least once (contrast to while loops)
The condition to reenter the loop is evaluated after – if met, the loop body is repeated, otherwise the loop exits.
that the condition to enter the loop body is reevaluated each time around the loop.

break and continue

As with the for-loop, it is possible to jump to the end of a loop block with the continue statement and break out of the loop early with the break statement.
