I'm getting a message from a server which has an intel dual core processor and Windows. The message is supposed to be a bunch of binary single-precision floating point numbers. The size of the numbers appear to be the same as the Java float, but the format does not seem to be the same. I used...

How can I interact with variables in my CChildView class from other objects? I have tried AfxGetMainWnd()->int GetVariable(), which compiled fine, but does not return the correct number. While debugging I noticed that somehow it changed from 5 to 0 once CChildView::GetVariable was called. I...

After code with the modulus operator (%) is compiled how does the CPU process it? I mean does it have some sort of efficient way of makeing x % y take up less processing power than if we just put it in a loop that calcualtes it? Same thing with powers. If we could (I don't believe we can) do...
