Even Numbers - Individual Exercise

Start by creating a new .cs file/project. Then, follow the instructions below to create a program that prints some even numbers.

Part 1 - Starting from 0

1. Declare a new variable x and set its value to 0
2. Use an if statement to check if x is even
   • Use the % operator to accomplish this: if any number % 2 equals 0, that means it is even
3. If x is even, print it to the console

At the end of this part, the program should print 0 to the console (it is already known that x is even)

Part 2 - While Loop

Instead of simply using 0, the program should iterate through 0, 1, 2, 3, ..., all the way to 100.

1. Above the if statement, create the while loop
   • while keyword
   • Parentheses ()
   • Curly brackets {}
2. Within the parentheses, use a condition to make sure the count is capped at 100
   • HINT: Compare x to 100 in some way
3. In the body of the while loop (between the curly braces), increment the value of x by 1

At the end of this part, the loop should execute 101 times... but it's missing something

Part 3 - Putting it all together

The last step is to put the check for evenness within the body of the while!

1. Copy the if code that checks a number's evenness
   • Include the if, and the body that prints to the console
2. Paste the if code within the while loop
   • Make sure it comes before the increment of x

Now, the program should print out each even number: 0, 2, 4, 6, ..., 100!

BONUS - User Input

Lastly, instead of using 100 as the cap, the program should ask the user which number to use.
