repeat loop
do loop
do while
repeat
<programming> (Or "do loop", "repeat until") 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, "Hello" is printed once despite the fact that the
condition is false;
i = 2;
do
print "Hello"
i = i + 1
while (i < 1);
See also while loop, for loop, loop-and-a-half.
