rounding a number that contains a decimal point is a common requirement. Similar rounding functions are also available in C + +. There are floor () and ceil () functions in the header file of C + +. There is also a round () function in the STL. The

First, C + + in 1, virtual function (virtual) The first time you introduce a base class for a virtual function, you must specify the virtual keyword in the class declaration. If the definition of a virtual function is placed outside the class, the
