what is the need for_in loop in the program ?
Welcome to the forums!
The for loop in
printExercisePlan() is so that you print each of the exercises
Regimen.exercises. You currently only have one exercise (
pushUp) in your
mondayRegimen struct, but the
exercises property is an array, so it can store more than one. Try adding another exercise to
mondayRegimen.exercises and then call the
printExercisePlan() method again.
