关于自定义类型的代码看如下：

// out_of_range
    #include "iostream"
    using namespace std;
    #include <stdexcept> 
    #include "string"
    
    // out_of_range
    class Teacher
    {
    public:
    	Teacher(int age)
    	{
    		if (age > 100)
    		{
    			string  s = "年龄太大";
    			throw out_of_range(s);
    		}
    		this->age = age;
    	}
    protected:
    private:
    	int age;
    };
    
    void main61()
    {
    	try
    	{
    		Teacher t1(102);
    	}
    	catch (out_of_range e)
    	{
    		cout << e.what() << endl;
    	}
    
    	exception e;
    	system("pause");
    }
    
    //自定义异常类
    class MyException : public exception
    {
    public:
    	MyException(const char *p)
    	{
    		this->m_p = p;
    	}
    
    	virtual const char *  what()
    	{
    		cout << "MyException: 类型" << m_p << endl;
    		return m_p;
    	}
    protected:
    private:
    	const char *m_p;
    };
    
    void testMyExcept()
    {
    	throw MyException("函数异常");
    }
    void main()
    {
    	try
    	{
    		testMyExcept();
    	}
    	catch (MyException & e)
    	{
    		e.what();
    	}
    	catch (...)
    	{
    		cout << "未知 类型 " << endl;
    	}
    	system("pause");
    }
