Problems with unary operators

when I do

var counter = 1

while counter < 10 { print("Hello!") counter += 5 }

Hello! is printed 2 times, but when I do

var counter = 1

while counter < 10 { print("Hello!") counter += 1 }

it only prints Hello! 9 times

and when I do

var counter = 1

while 10 < counter { print("Hello!") counter += 1 }

it prints nothing! Please help!

Hi, the reason it only prints 9 times is because you argument specifies:

while counter < 10 {
    print("Hello!")
    counter += 1
}

// if you change this to <= 10 it will be printed 10 times

while counter <= 10 {
    print("Hello!")
    counter += 1
