QUESTION
I am creating a Snake game on Linux. I was using iostream
to that point when I realized I need a getch()
function included within the ncruses.h
. I had a draw method which was printing all board elements to the console while using std::cout
and every character was displaying correctly. I had the whole board. But when I switched to ncurses and rewrite all the std::cout
to printf
(), then the program starts to write just a parts of the board. It is all done in while cycle and every cycle board is redrawn.
I am a newbie so please be kind.
Here is my main.cpp
...ANSWER
Answered 2020-Jan-07 at 20:53The C library (printf()
) and the C++ library (std::cout
) buffer their output -- although by default the C and C++ library synchronize their buffers.
The ncurses library does raw (unbuffered) output, sometimes wrapped with in-band control sequences. If you mix output to the same device through the C or C++ library and the ncurses library, you're going to get garbage on your screen. Just like you have.
You should use only either the ncurses library or the standard library to handle input/output from the terminal. Do not mix them.
