Unresolved External Symbol is Unresolved

[itsbenbroughton]

Hi all, I'm getting the below error in the below code. What am I doing wrong?

LNK2001
unresolved external symbol "public: static char const DateProfile::GENDER_MALE_UP" (?GENDER_MALE_UP@DateProfile@@2DB)

#include <iostream>
#include <ctime>
#include <sstream>
using namespace std;

class DateProfile
{
private:
   char gender;

public:
   static const char GENDER_MALE_UP;
   static const char GENDER_MALE_LOW;

   bool setGender(char gen);
   char getGender() { return gender; };
};

char const GENDER_MALE_UP = 'M';
char const GENDER_MALE_LOW = 'm';

int main()
{
   return 0;
}

bool DateProfile::setGender(char gen)
{
   if (gen == GENDER_MALE_LOW || gen == GENDER_MALE_UP)
   {
      gender = gen;
      return true;
   }
   else
      return false;
}

Change the definitions to:

char const DateProfile::GENDER_MALE_UP = 'M';
char const DateProfile::GENDER_MALE_LOW = 'm';

I did that, and it worked. Thanks for the fix!
Could you tell me why I needed to add the class?

[naraku9333]

Because the variables are class members, you were creating separate variables.

That makes total sense. Thanks! I appreciate the troubleshooting and the lesson
