This program is in response to the assignment:
"Create a method named Sum()that accepts any number of integer parameters and displays their sum. Write a Main()method that demonstrates the Sum()method works correctly when passed one, three, five, or an array of 10 integers. Save the program as UsingSum.cs."
from Microsoft® Visual C#® 2008, An Introduction to Object-Oriented Programming, 3e, Joyce Farrell
My code in the "//step 1:" part is getting the CS0019 error, which states that it cannot be applied to operands of type 'bool' and 'int'
I highly suspect there are also other problems with this code, but it's a great improvement over what I had four hours ago...
