尝试在 timer.cpp 文件中抛出 TimerException 类型的异常时出现此错误。这是 timer_exception.h
1 #ifndef TIMER_EXCEPTION_H
2 #define TIMER_EXCEPTION_H
3
4 #include <iostream>
5 #include <string>
6
7 class TimerException{
8 friend std::ostream &operator <<(std::ostream &os, const TimerException e){
9 std::cout << " *** TIMER EXCEPTION *** " << e.message;
10 return os;
11 }
12 public:
13 TimerExeption(std::string message) : message(message) {}
14 private:
15 std::string message;
16 };
17
18
19 #endif
这是我的 timer.cpp 文件,其中正在实例化 TimerException
1 #include <ctime>
2 #include "timer.h"
3 #include "timer_exception.h"
4
5 void Timer::start(){
6 if(timer != 0) throw TimerException("Timer already started");
7 this->timer = clock();
8 }
