Question

尝试将类和对象放在头文件中并不断收到此错误，不确定是否因为我没有包含正确的文件或者它的编写错误。错误在第28行：iItemPrice [iCount]

    #include "stdafx.h"
#include <string>
#include <conio.h>
#include <array>
#include <vector>
#include "ItemsClass.h"
#include "A2main.cpp"
#include <iostream>

using namespace std;
ItemsClass::ItemsClass()
{
}

void ItemsClass::enter_items() {
    string sItmes[5];
    string sChoice;
    int iCount;
    int iItemPrice;
    int iNumOfItems;


    do {

        cout << "--------- ENTER NEW ITEMS ---------\n\nPlease enter the item Name: ";
        cin >> sItems[iCount];
        cout << "\nPlease enter the price of: " << sItems[iCount] << "\n";
        cin >> iItemPrice[iCount];
        cout << "\nWould you like to enter another item? Y/N \n";
        cin >> sChoice;

        if (sChoice == "Y" || sChoice == "y")
        {
            ++iCount;
            ++iNumOfItems;
        }

    } while ((sChoice == "Y" || sChoice == "y") && iNumOfItems < 5);

}

Answer 1

iItemPrice被声明为int。不是数组/指针。

声明为：

int iItemPrice[5];

Answer 2

iItemPrice不是数组。如果要使用int iItemPrice[size]创建数组，最好使用std::vector<int> iItemPrice

C ++下标需要数组或指针类型
