1. // 会出现warning 的代码！
   
2. class cInit
   
3. {
   
4. public:
   
5.     cInit(std::string str, int a) : str_(str), a_(a)
   
6.     { }
   
7. 
   
8. private:
   
9.     int a_;
   
10.     std::string str_;
    
11. };

1. // OK
   
2. class cInit
   
3. {
   
4. public:
   
5.     cInit(std::string str, int a) : str_(str), a_(a)
   
6.     { }
   
7. 
   
8. private:
   
9.     std::string str_;
   
10.     int a_;
    
11. };
