我是C ++的初学者,只是想知道如果有可能,我可以将计算结果放在最后一个“ for”循环中,该循环使用“ Product”类中的名称,数量和重量在另一个名为“价格”的类中计算总价和价格。对不起这个奇怪的问题,我只是很困惑如何相互使用类,如果可以的话...
#include <iostream>
#include <string>
using namespace std;
class Product
{
public:
string name;
int amount;
float weight;
void get()
{
cout << "Give product name,amount and weight : " << endl;
cin >> name >> amount >> weight;
}
void print()
{
cout << name << " - "<< amount<<" , " <<weight <<" kg"<< endl;
cout << "--------" << endl;
};
};
int main()
{
Product p[100];
int n;
cout << "Give the number of products you want to get : " << endl;
cin >> n;
for (int i = 0; i < n; i++)
{
p[i].get();
}
cout << "Product display: " << endl;
for (int i = 0; i < n; i++)
{
p[i].print();
}
float total = 0;
for (int i = 0; i < n; i++)
{
cout << "\nPrice of " << p[i].name << " " << p[i].amount * p[i].weight << " $" << endl;
total = p[i].amount * p[i].weight + total;
}
cout << "\nTotal: " << total << "$" << endl;
cin.get(); cin.get();
return 0;
}
初学者时有这样的问题很好。我只想提几点。
Product
。static
变量包含所有产品的总价。static
函数并通过产品数组作为参数,并循环遍历产品计算总价格并将其存储在静态变量中。希望这消除了您的疑问。
