Using C + + to transform _c language from std::string type to bool type

Using input string Flow: Std::istringstream

Copy Code code as follows:

BOOL B;
std::string s = "true";
Std::istringstream (s) >> Std::boolalpha >> B;

However, when the string s is "1", the above code cannot be converted correctly, and this should be done by:

Copy Code code as follows:

BOOL B;
std::string s = "1";
Istringstream (s) >> B;

Insufficient: In addition to conditional judgment statements, no other can be found at the same time to cover two kinds of simple methods.
