#include <iostream.h>
using namespace std;

class PropertyPortal;
class PropertyType;
class Commercial;
class Residential;
void main()
class PropertyPortal  
{
private:

        int NoOfUsers;
        int UAN;
        char* Name;

        public:
       void setNoOfUsers(int no); 
       void setUAN(int u);      
       void setName(int n); 
       int getNoOfUsers(); 
       int getUAN(); 
       char getName();
       int getPropertyInfo(); 
       //constructors of the class
       PropertyPortal(); 
       PropertyPortal(int, int, char);
       //destructor of the class
       ~PropertyPortal ();

       void setNoOfUsers(int no)
       {
                        NoOfUsers>=1;
                        }
                        void setUAN (int u);
                        {
                        NoOfUsers>=0;

                        }
                        PropertyPortal (int no, int u, char* n)
                        {

        };          
class Commercial:PropertyType     
{

        int PropertyValue
public:
       void setPropertyValue();
       int getPropertyValue();
       void getPlots();
       Commercial();
       Commercial(char);
       ~Commercial();
};

class Residential:PropertyType     
private:
        int PropertyValue;
public:
       void setPropertyValue();
       int getPropertyValue();
       int getPropertyCategory();     
};
void main ()
{
cout<<"This is just a prototype of all classes";
cout<<endl;
system("PAUSE");
}

I got error on line 2,32:2,10,103 Please help me to find out whats wrong and whats going on with the code.

Update

Answer 1

A lot of the errors are coming from having both function declarations and definitions inside the class. Do either

class Foo
{
    public:
        int func();
};
int Foo::func() { return 5; }

or

class Foo
{
    public:
        int func() { return 5; }
};

but not

class Foo
{
    public:
        int func();
        // ...
        int func() { return 5; }
};

I also see that you intend to have two constructors, one with default values, and one taking values from the creator. But then you do this:

PropertyPortal (int no, int u, char* n)
{
    NoOfUsers>=no;
    UAN=u
    Name=VU-Real-Estate;
}
PropertyPortal (int no, int u, char* n)
{
    NoOfUsers>=no; 
    UAN=u
    Name=n;
}

I suspect you really mean

PropertyPortal ()
{
    NoOfUsers=1;
    UAN=1;
    Name="VU-Real-Estate";
}
PropertyPortal (int no, int u, char* n)
{
    NoOfUsers=no; 
    UAN=u
    Name=strdup(n); // Remember to free() this later.
}

In fact, you'ld be even better off to scrap char*s all together, and use std::string, and maybe read about initializer lists.
