Nested class as a member in a class

선언과 초기화 분리하는 방법

예시)

class Customer {
public:
    Customer(void);
    Customer(string,char,int);
};

1. 선언

   #include "Customer.h"
   
   class Node {
     public:
   
        Node(void); //default constructor
        Node(string,char,int); //Node constructor with customer details
   
        Node* left;
        Node* right;
        Node* parent;
        Customer customer;
   };

2. 초기화

   Node::Node() : left(nullptr),
                 right(nullptr),
                 parent(nullptr),
                 customer() {}
   
   Node::Node(string x, char y, int z) : left(nullptr),
                                        right(nullptr),
                                        parent(nullptr),
                                        customer(x, y, z) {}

Example Solution

class MpccRos
{
    MPC *mpc;
}
MpccRos::MpccRos()
{
    mpc = new MPC( ... );
    mpc->runMPC();
}
