I'm not sure on how to do this program Please send your helpful results as soon as possible. I use DEV C++.

I need to write a program that will calculate the sum of even numbers between limits entered by the user. For example, if the user entered 4 and 10, the program would calculate 4+6+8+10 and print 28 as the answer. Note that the two numbers can be entered in any order and may be odd or even. Entering 11 and 3 would also result in an answer of 28.

Thank you 4 your help and response in advance.
