C++类的概念初步

为了研究C++的类的概念，写了个小程序来实际操作一下。

#include <iostream>using namespace std;class Miners {public:Miners();~Miners();void DispInfo(Miners miner);void SetSpeed(int speed);void SetLength(int length);void SetHeight(int height);int GetSpeed(void);int GetLength(void);int GetHeight(void);private:int Speed;int Length;int Height;};Miners::Miners(){Speed = 5;Length = 15;Height = 15;}Miners::~Miners(){}void Miners::DispInfo(Miners miner){cout << "Speed: " << miner.Speed << endl;cout << "Length: " << miner.Length << endl;cout << "Height: " << miner.Height << endl;}void Miners::SetSpeed(int speed){Speed = speed;}void Miners::SetLength(int length){Length = length;}void Miners::SetHeight(int height){Height = height;}int Miners::GetSpeed(){return Speed;}int Miners::GetLength(){return Length;}int Miners::GetHeight(){return Height;}int main(int argc , char *argv[]){Miners miner01;miner01.DispInfo(miner01);miner01.SetSpeed(20);miner01.SetLength(18);miner01.SetHeight(10);miner01.DispInfo(miner01);return 0;}
