Arrays cannot be returned in C ++! That is to say, in C ++, arrays cannot be treated as the return value of the function; otherwise, an error is returned during compilation!If you want to return the data, you can return the data in the pointer

C LanguageThere is a rule that each symbol should contain as many characters as possible. That is to say, the compiler willProgramThe method to break it down into symbols is to read from left to right one character at a time. If this character may

C #2.0 uses the anonymous method, which allows us to understand the delegate in an intuitive way. The anonymous method allows us to define code segments for a delegate object directly. When we create a delegate with only a small piece of code, the
