Comparing 2 Integers in C++

I get an error when I try to compare two integers in Qt.

if ((modus==2) & (move != -1))

error: invalid operands of types '<unresolved overloaded function type>' and 'int' to binary 'operator!='

Do I need other operators? I have googled but it seems that Qt uses the same. Thanks for your ansers

Thanks to you, but I found it. The variable "move" belongs to QPoint or something like this. I just renamed my varible and everything is doing fine. Thanks anyway.

If you're using a C++0x compiler, move might conflict with std::move(). I'm thinking that's what's causing the "unresolved overloaded function type" part of the error message.

The operator you're using (&) is a "binary and", not the "logical and" you seem to want (&&). Assuming both 'modus' and 'move' are of type int, it should work fine:

if (modus==2 && move!=-1) {
    // stuff
}

You should use && for the and-operation:

if ((modus==2) && (move != -1))
