函数参数的自动隐式类类型转换只能一次

   1: #include<iostream>
   2:  #include<string>
   3:  using namespace std;
   4:   class TEST {
   5:       public:
   6:      TEST(){
   7:        cout<<"TEST()"<<endl;
   8:      }
   9:      TEST(string b){
  10:        cout<<"TEST(string) "<<endl;
  11:      }
  12:           TEST(const TEST &t){
  13:        cout<<"cpy_test"<<endl;
  14:      }
  15:   }; 
  16:   int f(const TEST& b){
  17:     return 0;
  18:   }
  19:    int f1( TEST b){
  20:     return 0;
  21:   }
  22:  int main()
  23:  { 
  24:      TEST temp= TEST();
  25:      TEST t="sdfda";  //gcc下无法通过编译,改为string(“sdfda”),就可以了
  26:      f("1");//gcc下无法通过编译,改为string(“1”)就可以了
  27:      while(1){}
  28:      return 0;
  29:  }
