#Representign up and down arrows as characters code#
The Alt code for a triangle pointing up is 30 and the Alt code for a triangle pointing down is 31. These compilers use the name _getch () instead of getch () to indicate that it is a non-standard function. Hold the ‘Alt’ key while entering the numerical code for the symbol. Then drag the mouse to draw the arrows as you want, and you can format the arrows' styles as you need. is not an official Emoji, but it can be used as a Unicode character. An arrow pointing to the right represents a tab character, where you have pressed the Tab key. Make the arrows with keyboard shortcuts under Windows. Insert an arrow shape to a blank section of this worksheet by clicking Insert > Shapes, and choosing Up Arrow or Down Arrow from the Block Arrows section as you need. The character that Word calls No-Width Non Break is Unicode character 200D, Zero Width Joiner, which is represented as a rectangle enclosing a filled rectangle: Tab characters. These codes are returned by MinGW and Visual C++ on Windows.Ī handy program to see the action of getch () for various keys is: #include You can convert these data columns to arrows as following steps: 1. Please note that getch () is not standardized in any way, and these codes might vary from compiler to compiler. If the num-pad arrow keys (with NumLock off) are pressed, getch () returns 0 first instead of 224. It returns either 0 (0x00) or 224 (0圎0) first, and then returns a code identifying the key that was pressed.įor the arrow keys, it returns 224 first followed by 72 (up), 80 (down), 75 (left) and 77 (right). Getch () function returns two keycodes for arrow keys (and some other special keys), as mentioned in the comment by FatalError.
