Summary: 1. When an object (Object Reference) is passed as a parameter, a reference (equivalent to a pointer) is passed ). That is to say, the changes made to parameters in the function will affect the original objects. 2. When the basic type or

Today, I have discussed with my colleagues the issue of pointer and reference transfer. Some ideas are correct in terms of reasoning. However, because it is reasoning, it is not so confident to express your opinion, based on the principle that

Compare the two transfer methods: To pass variables by value, you need to copy the Real-Time Parameter memory to initialize the parameters. This will incur some overhead. When discussing simple variables, the overhead of built-in types (such as int
