To implement this function, you must call a system API. ExitWindowsEx The function is to log out of the current user, shut down the system, or restart the system. It sends a WM_QUERYENDSESSION message to all applications so that they can decide

  In many cases, the protocol used to send strings on the network is UDP. Here, we use the official UDP library of boost to encapsulate it, and an object is used for sending. Very convenient. The Code is as follows:   StringQueue encapsulation. The

The speed formula is used for solving, and the enumeration trigonometric function value is used for calculation; The formula for the speed from the tower to the ground is v0 * v0-vy * vy = 2 * g * h (v0 is the final speed, which is the vertical
