while

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
