> - Why is it hard in the 1st time?
> - Is the concept itself hard for you now?
> - Why will we be afraid of learning something we don't know?

#### While loop

==put your code in your note ^^==

(a) Write a While loop to print out 1 to 100
(b) Write a While loop(only 1 while loop) to print out 50 times "Be happy!"
and 50 times "And be sincere!"
