anyone could help, would greatly appreciated it

Code:

using namespace std;
int main(void)
{
       
        Person Kovan;
        Kovan.SetName("Kovan");
        Kovan.SetAge(20);
        Kovan.SayAge();
        Kovan.SayName();
        Kovan.Greeting1();
        Kovan.GoodBye();

       
        int retval;       
        cin >> retval;
        return retval;
}

class Person
{
        public:
                void SetName(char* chrName);
                void SetAge(int Age);
                char* GetName();

                void Greeting1();
                void SayName();
                void GoodBye();
                void SayAge();

        private:
                char* pName;
                unsigned int pAge;
};

void Person::SetAge (int Age){

        pAge = Age;

}

void Person::SetName(char* chrName)
{
        pName = chrName;
}

char* Person::GetName()
{

        return pName;
}

void Person::Greeting1()
{
        cout << "hi there how are you doing?" << endl;
}

void Person::SayName()
{
        cout << pName << endl;
}

void Person::GoodBye()
{
        cout << "See Ya Later" << endl;
}

void Person::SayAge()
{
        cout << pAge << endl;
}

Put the class and the functions before the main function.This works great.

Code:

---

#include <iostream>

using namespace std;


class Person
{
        public:
                void SetName(char* chrName);
                void SetAge(int Age);
                char* GetName();

                void Greeting1();
                void SayName();
                void GoodBye();
                void SayAge();

        private:
                char* pName;
                unsigned int pAge;
};

void Person::SetAge (int Age){

        pAge = Age;

}

void Person::SetName(char* chrName)
{
        pName = chrName;
}

char* Person::GetName()
{

        return pName;
}

void Person::Greeting1()
{
        cout << "hi there how are you doing?" << endl;
}

void Person::SayName()
{
        cout << pName << endl;
}

void Person::GoodBye()
{
        cout << "See Ya Later" << endl;
}

void Person::SayAge()
{
        cout << pAge << endl;
}


int main(int argc, char* argv[])
{
Person Kovan;
        Kovan.SetName("Kovan");
        Kovan.SetAge(20);
        Kovan.SayAge();
        Kovan.SayName();
        Kovan.Greeting1();
        Kovan.GoodBye();

       
        int retval;       
        cin >> retval;
        return retval;

}

hehe

that really does make sense doesnt it?

what if i put all those functions and the class into a .H file..
if i use the #include..
will that automatically put them before main() or do i need to do somethign special?
becuase if i remember correctly i tried to put them in a file a while ago and i use to get same error..

thanks anyways for the help
i will try that out

Sticking the class definition in a header file is a pretty standard use for header files I think.

Although don't put the code into the header, split it into another .cpp file, as in:

-- Person.h --

Code:

---

#ifndef __PERSON_H__
#define __PERSON_H__

#include <iostream>

using namespace std;

class Person {
public:
        void SetName(char* chrName);
        void SetAge(int Age);
        char* GetName();

        void Greeting1();
        void SayName();
        void GoodBye();
        void SayAge();

private:
        char* pName;
        unsigned int pAge;
};

#endif // __PERSON_H__

---

...and...
-- Person.cpp --

Code:

---

#include "Person.h"

void Person::SetAge (int Age) {

        pAge = Age;

}

void Person::SetName(char* chrName) {
        pName = chrName;
}

char* Person::GetName() {

        return pName;
}

void Person::Greeting1() {
        cout << "hi there how are you doing?" << endl;
}

void Person::SayName() {
        cout << pName << endl;
}

void Person::GoodBye() {
        cout << "See Ya Later" << endl;
}

void Person::SayAge() {
        cout << pAge << endl;
}

my bad
i meant another .cpp
