Delegate statement Public Delegate void mydelegate (string Str); Note 1. The delegate definition is similar to the method definition, but a delegate is added before, but the delegate is not a method and is a type. It is a special type and is better

We usually exchange two values. We use a temporary variable temp to exchange the values of A and B. The common practice is as follows: Temp =; A = B; B = temp; However, bitwise operations are much more convenient:Suppose a = 3, B = 4. To swap

What is C ++? These days, I have basically finished the hardware design and had time to review the software code, so I sorted out some knowledge points related to c ++. This topic summarizes the essential issues of C ++. Why does C ++ define such a
