C and C++, procedural and object-oriented

The difference between C and C++ in elevator handling

(Note: personal understanding)
Comparison and difference:
C language programs formulate specific processes, and proceed step by step according to the process.
C++ programs structure the process, and use the interface to access and call the class structure structure of different functions when needed.

Elevator class definition

#pragma once
namespace myelevator
{
class Elevator {
private:
    enum Status {UP = 1, DOWN = -1, STOP = 0};
    int direction;//方向
    int now_floor;//当前楼层
    int targer_floor;//目标楼层
    Elevator();
public:
    int floor();//显示当前楼层
    void to(int);//接受楼层指令
    ~Elevator() { }
};//电梯对象
}

Elevator class implementation

#include "elevator.h"
using nemespace myelevator;
Elevator::Elevator(){
    now_floor = 1;
}

int Elevator::floor(){
    return now_floor;
}

void Elevator::to(int floor){
    targer_floor = floor;
    if(now_floor > target_floor)
        direction = DOWN;
    else
        direction = UP;
    return;
}
