programming The
loop construct found in nearly all
imperative programming languages which executes one or more
instructions (the "loop body") repeatedly so long as some
condition evaluates to true. In contrast to a
repeat loop,
the loop body will not be executed at all if the condition is
false on entry to the while.
For example, in
C, a while loop is written
while (expr) statement;
where expr is any expression and statement is any
statement, including a compound statement within braces
