In the array object in C #, you can use the reverse () method to reverse the element order in the array. The reverse () method is a static method, so as a parameter, the array elements that need to be reversed are passed to the reverse () method.

1. Apart from static data members, data members cannot be explicitly initialized in the class body.   For example:Class first {Int Memi = 0; // ErrorDouble memd = 0.0; // Error}; Class data members are initialized through the class constructor.

I. Volatile usage You can declare a member function as volatile. If the value of a class object may be modified in a way that the compiler cannot control or detect, for example: if it is a data structure that represents the I/O port, it is
