独立完成的第一个c++面向对象程序（虽然很简单 以后会增加功能）

一个简单的商品展示程序

功能如下：

1.输出一张商品表（嘻嘻 就这一个功能）

代码如下：

#include<iostream>

#include<string>

using namespace std;

class Goods {

private:

int amount;

double price;

string name;

public:

Goods();

int AddAmount(int);

int LoseAmount(int);

int SetGoods(int,double,string);

int GetPrice();

int GetSumPrice();

int GetName();

int GetAmount();

~Goods();

};

 

Goods::Goods()

{

}

 

int Goods::SetGoods(int amount, double price, string name)

{

this->amount = amount;

this->price = price;

this->name = name;

return 0;

}

 

int Goods::GetPrice()

{

cout << price;

return 0;

}

 

int Goods::GetSumPrice()

{

cout << price*amount;

return 0;

}

 

int Goods::GetName()

{

cout << name;

return 0;

}

 

int Goods::GetAmount()

{

cout << amount;

return 0;

}

 

Goods::~Goods()

{

}

 

int main() {

int i, n, amount;

double price;

string name;

Goods S[200];

cout << "请输入商品种类：" << endl;

cin >> n ;

cout << "请依次输入数量，单价，商品名" << endl;

for (i = 0; i < n; i++) {

cin >> amount >> price >> name;

S[i].SetGoods(amount,price,name);

}

cout << "数量" << '\t' << "单价" << '\t' << "商品名" << '\t' << "总价" << endl;

for (i = 0; i < n; i++) {

S[i].GetAmount(); cout << '\t';

S[i].GetPrice(); cout << '\t';

S[i].GetName(); cout << '\t';

S[i].GetSumPrice(); cout << '\t';

cout << endl;

}

return 0;

}
