        Q1: For loop

• Write a for-loop to calculate the product of all even numbers under 12

(including 12).

• (Hint: the counter doesn’t have to be 1.)

Q2: While loop

• Write a while loop to ask for three values from a user, and sum them

up.

• Hint: (1) use Console.ReadLine() to get data from a user, and convert it

to an integer. (2) You can either use an array to sum them up after the

loop or directly sum them up inside the loop.
