Hi.
I'm wondering if you can modify values in memory locations that correspond to the screen.
I used to do this before, but now it doesn't work.
I'm trying to make a program that scrolls text on the screen, so I want a procedure that works fast. Printf(), or puts(), is too slow.
I will appreciatte any response, thanks. (good nigth!)

Depends on your OS. I don't think a protected mode operating system will allow you to do it.At any rate, the address would be (according to this reference book anyway)0xb8000000L, and each byte of text would be followed by a text-attribute byte (usually set to 0x07).
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; }
