(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

for loop.
