[Asp.net 5] Options-configuration file (2), asp. netoptions- I wrote an article about Options a long time ago. I opened it again in 2016 and found many changes.

Topic content:Your program is going to read an integer in the range [ -100000,100000]. Then, use Hanyu Pinyin to output each bit of this integer.If you enter 1234, the output:Yi er san siNote that there is a space between the pinyin for each word, but there is no space behind the last word. When a negative number is encountered, add "fu" at the beginning of the output, such as the 2341 output as:Fu er san si yiInput format:An integer that ranges from [ -100000,100000].Output format:The pinyin th

5-2 constructor of the derived class Time Limit: 1000 ms memory limit: 65536 k any questions? Click Here ^_^ Description Through this exercise, you can understand the definition and usage of the derived class constructor. Define a base class person with three protected data members: Name (char * type), gender sex (char type), age (INT type ); A constructor is used to initialize data members. A member fu

2) on the basis of the above program, redefine the Triangle class, where the logic is particularly simple set and get member functions, to be processed as inline member functions, defined directly within the class.3) Design The constructor of the Triangle class with parameters, namely triangle (double x, double y, double z), and the three-side length is given directly by the argument at invocation, so that the object can be initialized at the time of
