but when I add the same argument to the Player function in the cpp file #include "Player.h" #include Player::Player(string name) { } I get an error: identifier "string" is undefined and I get the same error in the header file as well so it effects that too. I tried including string in the cpp file in hopes of solving the problem but it did not work. I'm really desperate for a solution, guys. c++ share|improve this question asked Feb 8 '15 at 14:05 momomo 2015 2 It's missing the namespace before string. Did you try std::string? cplusplus.com/reference/string/string –Caramiriel Feb 8 '15 at 14:06 I doubt that the header change works as you say it does! –Lightness Races in Orbit Feb 10 '15 at 15:07 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted All STL types, algorithms etc are declared inside std namespace. To make your code compile, string type should also specify the namespace as: Player(std::string name); /* Most recommended */ or using namespace std; Player(string name); /* Least recommended, as it will pollute the available symbols */ or using std::string; Player(string name); share|improve this answer edited Feb 10 '15 at 14:37 answered Feb 8 '15 at 14:09 Gyapti Jain 2,398

Join them; it only takes a minute: Sign up Compiler Error - Identifier undefined up vote 0 down vote http://stackoverflow.com/questions/28394815/c-visual-studio-class-error-identifier-string-is-undefined favorite I have a fairly simple C++ code that doesn't seem to be compiling properly. Essentially, I have some globally defined functions declared in my GLOBAL.HPP file, and are defined in my GLOBAL.CPP file. Then I have a class, EuroOption, that consists of a struct datamember. The class EuroOption has its own member functions that essentially do the same exact thing that the global functions do--so I defined them http://stackoverflow.com/questions/17055942/compiler-error-identifier-undefined similarly, and just called global functions inside of the EuroOption member function definitions. Please see below: // //GLOBAL.HPP // #ifndef GLOBAL_HPP #define GLOBAL_HPP #include #include #include #include // For non-member functions of distributions using namespace std; //using namespace boost::math; namespace GLOBAL // Encapsulate Point in the Global namespace { struct EuroOptionData { double r; // Interest rate double sig; // Volatility double K; // Strike price double T; // Expiry date double b; // Cost of carry }; double n(double x); double N(double x); double CallPrice(EuroOptionData od, double S); double PutPrice(EuroOptionData od, double S); double PutParity(EuroOptionData od, double S); double CallParity (EuroOptionData od, double S); } // Close namespace GLOBAL #endif Here is the EuroOption.HPP file: // // // #ifndef EUROOPTION_HPP #define EUROOPTION_HPP #include #include "Global.hpp" using namespace std; using namespace GLOBAL; class EuroOption { private: public: struct EuroOptionData od; //EuroOption class functions EuroOption(); // Default call option EuroOption(const EuroOption& option2); // Copy constructor virtual ~EuroOption(); //Destructor //EuroOption Global Function Calls double EuroCallPrice(EuroOptionData od, double S); double EuroPutPrice(EuroOptionData od, double S); double EuroCallParity(EuroOptionData od, double S); double EuroPutParity(EuroOptionData od, double S); //EuroOption class operators EuroOption& operator = (const EuroOption& option2); //Assignment Operator }; #endif And a snippet of
