repeat loop definition
programming (Or "do loop") A
loop construct found in many
procedural languages which repeatedly executes some instructions while a
condition is true.
Repeat loops are found in
Perl,
Pascal,
BASIC and
C. The initial
keyword may be "repeat" or "do" and the condition may be introduced with a "while" or "until" keyword.
In constrast to a
while loop, the "loop body" is executed once before the condition is tested. This is useful when the condition depends on the action of the loop body. In the following BASIC loop "Hello" is printed once despite the fact that the condition is false;
i = 2 repeat print "Hello" i = i+1 until i>0
