Here, we will add the "aricc" protocol as an example.
I. First, write a program that supports the aricc ProtocolProgram. Let's use C # To write a sample program.
1. Create a Windows application.
2. Add a Textbox Control to the form.

When constructing various types of data into strings, the powerful features of sprintf seldom disappoint you. Since sprintf and printf have almost the same usage, but the printing destination is different, the former is printed into the string, and
Char acstr [] = "AAAAA"; // This is a character array containing only five charactersChar * pcstr = "AAAAA"; // This is a string containing 6 characters, that is, adding an Terminator '\ 0' to five a's'
The output strlen () is 5 in length,
Class test { Public: Int get_value () {return value ;} PRIVATE: Int value; }; Requires no friend yuan. Do not add anyCodeTo change the value of member variable k to 100. The result is naturally verified by the Public member function get_value.
When you study C # In actual work, you may ask: why do we need to provide some existing functions (for example, some functions in windows, some methods that have been compiled in C ++) to rewrite
Code , C # Is there a way to directly use these
Iterator Overview
An iterator is a sequence that can return values of the same type.Code.
The iterator can be used as a method, operator, or get accessors code body.
The iterator Code uses the yield return statement to return each element in
