這個程式如果你按A他會一直出現A 你按B他會一直出現B 隨便按停止它不會等待輸入也不用按enter 程式碼 --------------------------------------------------------------------- #include <stdio.h> #include <windows.h> #include <string.h> int main(){ HANDLE handle = GetStdHandle(STD_INPUT_HANDLE); DWORD events; int key=0; INPUT_RECORD buffer; PeekConsoleInput( handle, &buffer, 1, &events ); while(1){ PeekConsoleInput(handle, &buffer, 1, &events); if(events > 0) { ReadConsoleInput(handle, &buffer, 1, &events); if (buffer.Event.KeyEvent.wVirtualKeyCode=='A'){ key=1; } else if (buffer.Event.KeyEvent.wVirtualKeyCode=='B'){ key=2; } else{ key=3; } } if (key==1){ printf("A"); } else if (key==2){ printf("B"); } else if (key==0){ } else { return 0; } } } ------------------------------------------------------ 參考資料: http://stackoverflow.com/questions/421860/ c-c-capture-characters-from- standard-input-without-waiting-for-enter-to-be-pre -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.135.96.181
