是否有預處理器AND
指令?如果不是,你會如何建議我解決以下任務?是否有預處理器「AND」指令
#define INSTALL_V8
#define INSTALL_V9
#define INSTALL_V10 // Using preprocessor directives and not static variables to
// avoid packaging unnecessary code into the application/installer
#ifdef INSTALL_V8 AND INSTALL_V9 AND INSTALL_V10
#define CHECK_BOX_STRT_Y 60 // move the start y up so we have room to fit 3 checkboxes in the window
#else
#define CHECK_BOX_STRT_Y 80 // place 1st checkbox in middle of window
#endif
