Description
Statement; tests an expression and runs a statement or series of statements repeatedly in a loop as
long as the expression is
true.
Before the statement block is run, the
condition is tested; if the test returns true, the statement
block is run. If the condition is
false, the statement block is skipped and the first statement after
the
while action’s statement block is executed.
Looping is commonly used to perform an action while a counter variable is less than a specified
value. At the end of each loop, the counter is incremented until the specified value is reached. At
that point, the
condition is no longer true, and the loop ends.
The
while statement performs the following series of steps. Each repetition of steps 1–4 is called
an iteration of the loop. The
condition is retested at the beginning of each iteration, as in the
following steps:
1 The expression condition is evaluated.
2 If condition evaluates to true or a value that converts to the Boolean value true, such as a
nonzero number, go to step 3.
Otherwise, the
while statement is completed and execution resumes at the next statement
after the
while loop.
3 Run the statement block statement(s).
4 Go to step 1.
