For example, there are three programs of a, B and C, of which A and V1.00 and V1.10 two versions.Premise:1) The interface between the programs does not detect changes;2) two times the data input to a is the same;3) Three programs do not have abnormal bullets in operation, or other problems appear.Operation Result:A V1.00 with B and C, the result is normal, repeat operation, also normal;A V1.10 run with B and C, you don't get the results you want. Repeating the test is the same conclusion.Problem

UsedC ++TargetedObjectUsers of programming know that objects in a program rarely exist independently. It is almost impossible to ignore the interaction between objects. Therefore, it is an important task of object-oriented programming to identify the relationship between objects or establish a message connection between objects. This paper proposes a practical method for establishing message connections between objects from the perspective of C ++
