In C #, there are no free functions and no free variables. Everything must be encapsulated in the class. In C ++, using global variables for inter-function communication and inter-class communication are common methods. However, this becomes impossible in C, this indeed makes

The standard code for the singleton pattern implementation in C + + is:

At the same time, the conversion of method groups and delegates is also supported. By the way, the covariance and contravariance of delegates are increased in the
