C++ conio library4/8/2023 If it worked for you, then you are lucky. Now, the enterprising among you may have already tried to compile this. Printf( "Greetings and salutations %s!\n", users_name ) (See Wikipedia's Conio article for a very succinct description of its limitations.)įgets( users_name, sizeof( users_name ), stdin ) Hence, for anything other than Windows programs it is also a sub-optimal solution. The caveat is that it is non-standard, meaning that the actual functions it provides vary a lot and they don't always behave just right. However, given the choice, use Curses instead. This library is severely deprecated, but it is so popular (due to hysterical raisins) that some form of it exists on most 80x86 hardware compilers -almost always on Windows compilers, and there exist Linux versions too. (If you do use Curses, see NCurses for Unix and Linux and other POSIX systems, and PDCurses for DOS, Windows, OS/2, and some other random systems.) Printw( "Greetings and salutations %s!\n", users_name ) Īgain, if all you want to do is clear the screen on occasion, then it is complete overkill to use Curses. */ /* (Remember, when using Curses, no change will appear */ /* on the screen until refresh() is called. Getnstr( users_name, sizeof( users_name ) - 1 ) See Why system() is evil for more information. The following methods are usually supported by a wide variety of platforms, but have significant tradeoffs in functionality or utility or both. If you don't know what that entails, don't worry about it. If you know yourself to be using just one, you can get rid of everything except for the proper #includes. Throughout this article the code snippits will not assume either C or C , so the #include section will be bracketed by the appropriate #ifdef tests depending on which language you are using. This short article describes the method of clearing the console display of all text and positioning the text cursor in the home location (the upper-left corner).īefore becoming too comfortable doing this kind of thing blithely, make sure you read and understand about the types and purposes of console applications (and why it matters).
