C++自定义异常处理

自定义异常类

 1 class MyException
 2 {
 3 public:
 4     MyException()
 5     {
 6     }
 7 
 8     MyException(char* str)
 9     {
10         msg = str;
11     }
12 
13     MyException(MyException& rhs)
14     {
15         this->msg = rhs.msg;
16     }
17 
18     std::string msg;
19 };

 

抛出异常

1 void CallWithException()
2 {
3     char msg[1024] = { 0 };
4     sprintf(msg, "Exception: %s", "shit");
5     throw MyException(msg);
6 }

 

捕捉异常

1 try
2 {
3     CallWithException();
4 }
5 catch (MyException& e)
6 {
7     cout << e.msg;
8 }
