View 5 RepliesI am supposed to create a program in my VB.net class to do the following:
1. Prompt the user to enter the beginning number and the ending number.
2. Find the sum of the even numbers between these two values, inclusive.
[Code]...
We are currently using for next statements in the class. I know how to prompt for and utilize the numbers that are input etc. My problem is the EVEN numbers part. I obviously have to determine if the number is even and then use a step value of 2 from there. But not sure how to determine if number is even or odd (guessing to use mod, but totally lost).
