C++ arrays

Greetings forum members!
My name is Steven. But I'm known as Tech2011 around various sites.
I am new to this forum. Anyways, I have a quick question about C++ arrays.

So I was hoping to design an array with each array value would increment to the next value.
My code is displayed below. I will then explain my problem.

cout << "Please enter an integer." << "\n" ;
int userint;
cin >> userint;
cin.ignore();

int arraybuildup[2];
arraybuildup[0]=userint;
arraybuildup[1]=userint++;


cout << arraybuildup[1];

I can't explain why, but for some reason, when a value is given for "userint", it outputs the same value on the screen, instead of the incremental value. This is not what I intended.
If anyone has an idea or solution, your thoughts would be most certainly appreciated!
Thanks for your support!

userint++
gets evaluated after the expression does.

If only those Postfix increment operators had a meaningful name.....

Yeah you probably want the prefix version, not the postfix one. (Put the ++ in front of the variable)
