Another variation on the while loop is an until loop, a syntax that is available in the program m ing language Perl (C doesn't use this syntax). An until loop is sim ply a while loop with the conditional statem ent inverted. The sam e m ouse program using an until loop would be:
Until (you are not hungry)
{ Find some food; Eat the food
Until (you are not hungry)
{ Find some food; Eat the food
