c++ - 在收据中显示所有用户的选择
问题描述
我是编程新手，最近我创建了一个程序，该程序应允许用户从菜单中选择任意数量的项目。一旦用户完成，它应该显示总成本和他们订购的物品，但它只显示用户选择的最后一个物品。金额是正确的，总计很好，但它不会显示所有项目。下面是代码：
#include<iostream>
#include<unistd.h>
#include<ctime>
using namespace std;
int main()
{
string name, address, numphone, choice;
int quantityF1, quantityF2, quantityF3, quantityF4, quantityF5, quantityF6, quantityF7, quantityF8, quantityB1, quantityB2, quantityB3, quantityB4, quantityB5;

int paymentMethod, quantity;

解决方案
嗯，这很正常，choice每次客户用getline(cin,choice);.
您可能想要查看的是数组或向量。在您的书/教程中可能不会遥遥领先；）
