尝试从类

Question

调用函数我试图通过创建一个对象执行.h文件中的代码..我做错了什么？

//TicketFineCalculator.h 
#include <iostream> 
using namespace std; 

class TicketFineCalculator 
{ 

    public: 
int getFine() { 
     int procFee, zone, speedLimit, actualSpeed, totalFine; 
    int anotherRun = 1; 
    while (anotherRun == 1){ 
cout << "\n-------------------------------"; 
cout << "\nSpeeding Ticket Fine Calculator"; 
cout << "\n-------------------------------"; 
cout << "\nEnter processing fee, in dollars:"; 
cin >> procFee; 
cout << "\nSpeeding Ticket #1"; 
cout << "\nEnter the type of speeding offense (1 for regular, 2 for work zone, 3 for residential district):"; 
cin >> zone; 

cout << "\nEnter the speed limit, in miles per hour:"; 
cin >> speedLimit; 
cout << "\nEnter the vehicle's speed, in miles per hour:"; 
cin >> actualSpeed; 
cout << "\nThe total fine is:" << totalFine; 
cout << "\nEnter 1 to enter process another speeding ticket or 0 to quit:"; 
cin >> anotherRun; 
    } // terminates while loop 
return totalFine; 
     } 
// Calculate the total fine given the road zone, speed limit, and the vehicle's actual speed. 
// Return the fine as an integer. 

}; 


//Project1.cpp 
#include <iostream> 
#include "TicketFineCalculator.h" 

int totalFine; 
TicketFineCalculator::getFine(totalFine); 

    int main(){ 
    cout << totalFine; 
return 0; 
} //terminates main

如果你想打电话内TicketFineCalculator的getFine（）方法时，必须声明静态方法，如下所示：

class TicketFineCalculator 
{ 
public: 
    static getFine() 
    { 
    } 
}; 

，或者你必须创建TicketFineCalculator的一个实例，并调用使用该方法实例。
