    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!

    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)
