virtual function is supported by a pointer to the VTBL (virtual function table) of a class object vptr. The vptr settings and resets are automatically completed by the constructors, destructors, and copy assignment operators of the class.
Almost every class we design has one or more constructors, destructors, and a assignment operator. Their role is that the constructor creates a new object and determines that it is initialized. The destructor destroys an object and determines that it has been

Maja is a bee. She lives in a bee hive with thousands of the other bees. This bee hive consists of many hexagonal honey combs where the honey are stored in. But Bee Maja has a problem. Willi told her where she can meet him, but because, Willi are a male drone and Maja is a female worker they have diffe

1. Pick the mines you want to dig: When you come to the asteroid belt and you are ready to dig, you can select the triangle arrows in the general View window and turn the ' load default ' to ' mining so that you can show the names and distances of all the mines in the window below. You can see that there are so many kinds of mines here, there are high and low level, in order to observe the need, we need to remove the mine from the window. At this point we can right-click on those

Flying their own assembled UAV is fun, then this article introduces the installation of the essential ground station software Qgroundcontrol to play UAV, of course, can also use Mission Planner ground station. QGC and both can be installed under Windows. This article desc

Ubuntu has revealed to the outside that their newest idea of Iot is to make Linux the core of making Iot more intelligent and scalable. SnappyUbuntuCore is the latest platform for smart devices. It promises to run the same software stored locally or on the cloud. Obviously, the biggest benefit of the latter is that users can avoid frequent regular upgrades. For Ubuntu, the biggest advantage of the platform over competitors is its current user base. For example, ErleRobo
