Getting compilation error: "identifier 'objUser' is undefined" in my main() function - c++

Question

I'm trying to call the functions from my clsFamily class within the main, however, when I pass down the (&objUser) I get a message stating:
identifier 'objUser' is undefined
Edit: Sorry forgot to mention but I want a dynamic vector array that is manipulated based on the users choice.
Any help at all will be kindly appreciated as it is for an assignment that is due next Thursday xD
int UserChoice();
int UserChoice()
{
int iChoice = 0;
int iAdults = 0;
int iChildren = 0;
cout << "How many family members do you have? \n";
cin >> iChoice;
cout << "How many of these are adults? \n";
cin >> iAdults;
cout << "How many of these are children? \n";
cin >> iChildren;
return iChoice;
return iAdults;
return iChildren;
}
class clsUser
{
private:
string m_sName;
int m_iAge;
public:
void SetName(string);
string GetName();
void SetAge(int);
int GetAge();
clsUser();
~clsUser();
clsUser(string, int);
};
//This is to group the singular users into a group using a vector
class clsFamily
{
private:
vector <clsUser> objUser;
public:
void InputFamilyDetails(vector <clsUser> *objUser);
void OutputFamilyDetails(vector <clsUser> *objUser);
};
void clsFamily::InputFamilyDetails(vector <clsUser>* objUser)
{
string sName = "";
int iAge = 0;
for (int iCount = 0; iCount < objUser->size(); iCount++)
{
cout << "Please enter the name of family member " << iCount + 1 << "\n";
cin >> sName;
cout << "Please enter the age of family member " << iCount + 1 << "\n";
cin >> iAge;
objUser->at(iCount).SetName(sName);
objUser->at(iCount).SetAge(iAge);
}
}
//This is to allow the user to input the the details of the users from the vector
void clsFamily::OutputFamilyDetails(vector <clsUser>* objUser)
{
for (int iCount = 0; iCount < objUser->size(); iCount++)
{
cout << "The name of family member " << iCount + 1 << " is " << objUser->at(iCount).GetName() << " \n";
cout << "The age of family member " << iCount + 1 << " is " << objUser->at(iCount).GetAge()<< " \n";
}
}
int main()
{
clsFamily objFamily;
*//This is the area where the problem is occuring*
objFamily.InputFamilyDetails(&objUser);
objFamily.OutputFamilyDetails(&objUser);
}

clsFamily already has an objUser member. You shouldn't use it and not expect a parameter in InputFamiliyDetails and OutputFamilyDetails:
class clsFamily
{
private:
vector <clsUser> objUser; // Needs to be initialized with some size, though
public:
void InputFamilyDetails();
void OutputFamilyDetails();
};
void clsFamily::InputFamilyDetails()
{
string sName = "";
int iAge = 0;
for (int iCount = 0; iCount < objUser.size(); iCount++)
{
cout << "Please enter the name of family member " << iCount + 1 << "\n";
cin >> sName;
cout << "Please enter the age of family member " << iCount + 1 << "\n";
cin >> iAge;
objUser.at(iCount).SetName(sName);
objUser.at(iCount).SetAge(iAge);
}
}
void clsFamily::OutputFamilyDetails()
{
for (int iCount = 0; iCount < objUser.size(); iCount++)
{
cout << "The name of family member " << iCount + 1 << " is " << objUser.at(iCount).GetName() << " \n";
cout << "The age of family member " << iCount + 1 << " is " << objUser.at(iCount).GetAge()<< " \n";
}
}
int main()
{
clsFamily objFamily;
objFamily.InputFamilyDetails();
objFamily.OutputFamilyDetails();
}
