1. We know that in C + + class member functions, the default implies a this pointer, which identifies the object that called the member function2. Why is it necessary to have a this pointer? What is the purpose of the C + + design mechanism?We know

The composite type in LUA is only the table type, and you can use it as any container, such as the std::map in the associative array C + + in the array php, and so on, and it provides a handyThe following is the use of table types in LuaC + + Load

The storage of adjacency matrices is more convenient and easier to understand than adjacency tables.The adjacency matrix uses a two-dimensional array matrix to store the relationship of every two points. If there is an edge between the two point m,n,
