    here's your code......

    dineout.hpp
    Code:
    #ifndef INCLUDED_DINEOUT_H
    #define INCLUDED_DINEOUT_H
    #endif
    
    class DineOut
    {
    public:
    	DineOut(int value);
    	~DineOut();
    	
    	int FiftyTimes();
    	int Twice();
    	int AddFive();
    	int HadBirth();
    	int NotHadBirth();
    
    
    private:
    	int x;
    };
    
    
    DineOut::DineOut(int value)
    {
    	x=value;
    }
    
    DineOut::~DineOut()
    {
    }
    
    int DineOut::FiftyTimes()
    {
     return x*=50;
    }
    
    int DineOut::Twice()
    {
     return x*=2;
    }
    
    int DineOut::AddFive()
    {
     return x+=5;
    }
    
    int DineOut::HadBirth()
    {
     return x+=1753;
    }
    
    int DineOut::NotHadBirth()
    {
     return x+=1752;
    }
    main.cpp

    Code:
    #include <iostream>
    using namespace std;
    #include "dineout.hpp"
    
    
    int main()
    {
      int i;
      cout << "Enter the number: " <<flush;
      cin >> i;
      DineOut myObject(i);
      cout << i << " after adding 5: " << myObject.AddFive() << endl;
      cout << i << " after adding 1753: " << myObject.HadBirth() << endl;
      return 0;
    }

    50 DineOut.h candidates are: int DineOut::NotHadBirth(int)

    23 diningoutmath.cpp no matching function for call to `DineOut:ineOut (int &)'

    20 DineOut.h candidates are: DineOut:ineOut()

    It repeats these comments for different lines throughout the program, why?

    Your .CPP file is almost correct, but your class is still very incorrectly defined. None of those functions should take parameters except the constructor.

    Use CodingMaster's version of the class; it's much closer to what you need.

    Instead of putting cout on every output line and closing the statement can't he just do this


    Code:
    cout << "Blah Blah"
            << endl 
            << "See I didnt' end those statements so I dont need cout";

    Instead of....

    Code:
    cout << "Blah blah";
    cout << endl;
    cout << Man what unneeded work I'm doing ending each time.";
    Will that work in normal compilers? Its accepted in VC++ 6 but I don't know about the others..
