I read somewhere that I could stop the user from effectively filling up a buffer and doing stuff before it appears on the screen. Such as say repeatily hitting the y button and having it go through a menu before they can see it. I would like to know how to do this without making them type anything extra to get out of it.

Could you explain that a little better? Do you mean:
1) Process user input before the enter key is pressed?
2) Prevent user from overwriting your buffer?
3) Something else?
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
I have this small program, and in it I call several getch()'s and I have a couple delays so the screen doesnt update instantly. However, I want to stop the user from inputing anything before they have a chance to read the screen.

I don't know. I have only been programming for a few months now, but my intuition tells me that there is no standard way to do this but that it is possible if not in a roundabout way.
Hmm, try this:
// do screeen stuff...meanwhile user is busy filling up the buffer
//screen appears
fflush(stdin);
//Now scan in user input with gets(), scanf(), or whatever...
I am pretty sure that will work, now that I think about it...
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Well it isnt exactly working the way i want it to, as in it is doing nothing, and the compiler is accepting it. does it consider stdin to be a file?

Didn't you want it to ignore user input till after they view the screen? Post your code and I will play with it...
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Going to bed... will check in the morning...
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
I'd rather not post my code to the board, perhaps you could give me your email address, I can send it there, its about 30kb... although im going to bed right now too, so ill see you in the morning.

FYI: If you look at the bottom of most members posts, you will see a button labeled e-mail...also you can send the code as an attachment in your post....
My e-mail is [email protected]
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
After years of surfing the internet there are certain things I automatically ignore, those buttons just happened to be one of them. I hardly see advertisements anymore just because I've encountered almost every type there are. Although, now I do see those buttons, and ill be sending the file as soon as possible.
