CS 0007 – Lab 2

Simple Looping

For this lab, write a program to compute 3 sums based on user input. The user will input a number (let’s call it N) and you should tell the user:

1. The sum from 1 to N
2. The sum of the even numbers from 1 to N
3. The sum of the odd numbers from 1 to N

The purpose of this assignment is to get familiar with looping and to use the shortcut operators like += and ++ wherever possible.

Example

Enter a positive integer:

30

The sum is 465

The sum of the evens is 240

The sum of the odds is 225

Hints

• To determine if a number is odd or even, take it mod 2.
• You can use either a while or a for loop
• Remember to use shortcut operators!

When you’re done, have Rasoul check you off here: __________ and you can go.
