while

<programming> The loop construct found in nearly all procedural 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

 "{..}".
