클래스 타이머에 접두사 및 접미사 증가분을 오버로드합니다. 디버깅 중 문제

Question

Timer 클래스의 증가분을 오버로드해야합니다. 수업 시간은 분, 초입니다. 기본 컴파일러 건물 메이크 :

#include <iostream> 
#include <conio.h> 
using namespace std; 

class Timer 
{ 
private: 
    int minutes;   
    int seconds;    

public: 

    Time(){ 
    minutes = 0; 
    seconds = 0; 

    } 
    Time(int m, int s){ 
    minutes = m; 
    seconds = s; 

    } 

    void displayTime() 
    { 
    cout << "M: " << hours << " S:" << minutes <<endl; 
    } 

    Time operator++() 
    { 
    ++seconds;   
    if(seconds >= 60) 
    { 
     ++minutes; 
     seconds -= 60; 
    } 
    return Time(minutes, seconds); 
    } 

    Time operator++(int)   
    { 

    Time T(minutes, seconds); 

    ++seconds;      
    if(seconds >= 60) 
    { 
     ++minutes; 
     seconds -= 60; 
    } 

    return T; 
    } 
    }; 
    int main() 
    { 
    Time T1(18, 23), T2(19,12); 

    ++T1;      
    T1.displayTime();  
    ++T1;     
    T1.displayTime();  

    T2++;     
    T2.displayTime();  
    T2++;     
    T2.displayTime();  
    _getch() 
    } 

내가 디버깅 할 때, 그것은

Answer 1

개체 유형은 타이머가 아님 시간이어야합니다. 클래스 이름과 생성자 이름을 일치 시키려고합니다.

Hour 멤버가 displayTime 메서드에 정의되지 않았습니다.

void displayTime() 
    { 
    cout << "M: " << minutes << " S:" << seconds <<endl; 
    }
