[英]Class “error identifier is undefined”
我假設這是一個小語法問題,因為當我刪除該類並僅在我的cpp文件中工作時,它可以正常運行...
我需要使用主函數將調用的類。 我遇到的問題是它們在.cpp文件中沒有重新識別。
如果在頭文件中聲明數組或常量會更好,請讓我知道...
#include '<iostream>'
#include "Menu.h"
using namespace std;
const double RestaurantCheck::MINTAX=.01, RestaurantCheck::MAXTAX=.12,RestaurantCheck::MINTIP=.05,RestaurantCheck::MAXTIP=.20,RestaurantCheck::DEFAULTTAX=.065,RestaurantCheck::DEFAULTTIP=.15;
//Error nonstatic data member may not be defiend outside of its class
RestaurantCheck::MexicanMenu[10].ItemName="Marisco El Sol";
RestaurantCheck::MexicanMenu[10].ItemDesc="Mouth watering seafood appetizer made with shrimp, octopus, scallops, mushrooms, red and green peppers. Garnished with lettuce and avocado.";
RestaurantCheck::MexicanMenu[10].ItemCost=10.95;
RestaurantCheck::MexicanMenu[1].ItemName="Taquitos";
RestaurantCheck::MexicanMenu[1].ItemDesc="Rolled flour tortilla fried with your choice of chicken, shredded beef or shredded pork. Served over a bed of lettuce with Parmesan, tomatoes, guacamole & sour cream.";
RestaurantCheck::MexicanMenu[1].ItemCost=7.95;
...
RestaurantCheck::MexicanMenu[0].ItemName=" ";//my null set.
RestaurantCheck::MexicanMenu[0].ItemDesc=" ";
RestaurantCheck::MexicanMenu[0].ItemCost=0;
void main()
{
double ITax=0,ITip=0,Subtotal=0,UserTip=0,UserTax=0;
bool exit=false;
int count=0;//delete me after tests
while (exit=false)
{
cout<<"Please input all tips as floating numbers 1% = .01 and 12% = .12\n";
cout<<"What value do you want to set the tip? ";
cin>>UserTip;
cout<<endl<<"What value do you want to set the tax? ";
cin>>UserTax;
setFee(UserTip,UserTax);//error: Identifier is undefined
placeOrder();...

setFee()
是RestaurantCheck
類的成員函數,因此您需要該類的實例才能調用該方法。
RestaurantCheck r;
r.setFee(x,y);
解決此問題后,您會發現很多很多錯誤。
