我应该使用一个并行数组来显示一杯咖啡是基于添加了什么插件。原版咖啡是2美元。我很困惑如何输出正确的结果。目前,它将输出“Order total is2”。我错过了什么?
// JumpinJava.cpp - This program looks up and prints the names and prices of coffee orders.
// Input: Interactive
// Output: Name and price of coffee orders or error message if add-in is not found
#include <iostream>
#include <string>
using namespace std;
int main()
{
// Declare variables.
string addIn; // Add-in ordered
const int NUM_ITEMS = 5; // Named constant
// Initialized array of add-ins
string addIns[] = {"Cream", "Cinnamon", "Chocolate", "Amaretto", "Whiskey"};
// Initialized array of add-in prices
double addInPrices[] = {.89, .25, .59, 1.50, 1.75};
bool foundIt = false; // Flag variable
int x; // Loop control variable
double orderTotal = 2.00; // All orders start with a 2.00 charge
// Get user input
cout << "Enter coffee add-in or XXX to quit: ";
cin >> addIn;
// Write the rest of the program here.
for(int i = 0; i < NUM_ITEMS; i++){
if (addIns[i] == (addIn))
foundIt = true;
if (foundIt)
{
x = orderTotal + addInPrices[i];
cout << "Order Total is" << x << endl;
}
else cout <<"Sorry, we do not carry that."<< endl;
}
return 0;
} // End of main()
