 };

Per the comments you are including ncurses.h , which contains

#define KEY_LEFT 0404 /* left-arrow key */

That is a macro, which will automatically be substituted by the preprocessor, turning your code into

const int 0404 = 'a' /* ... */;

0404 is not a valid variable name, so your code does not compile. In general, you could try to redefine these macros (via #define ). However, redefining them may cause havoc in other places.

If you are trying to treat a just like ← , I would recommand checking for the appropriate key instead of (or alongside to) KEY_LEFT in whatever place you use that macro.
