Problem with "Information Hiding"

[stickfigure02]

Why cant I compile this to get an object file for the actual class function definitions. It’s for information hiding. Here are my 3 files...

dayType.h

#include <iostream> //Import header files
#include <string>

using namespace std;

class dayType {
//Public member function prototypes of dayType    
public:
    void print();
    string returnDay();
    string nextDay();
    string prevDay();
    string newDay(int numOfDays);
    dayType(string day);
//Private members of dayType    
private:
    string currentDay;
    int dayNumber;
    string days[7]; 
}; 

dayTypeImp.cpp

#include <iostream> //Import header files
#include <string>
#include "dayType.h"

using namespace std;

void dayType::print()//Function to print the current day
{
    cout << currentDay;
}
string dayType::returnDay()//Function to return the current day
{
    return days[dayNumber];
}
string dayType::nextDay()//Function to return the next day
{
    if (dayNumber == 6)
        return days[0];
    return days[dayNumber + 1];
} 
string dayType::prevDay()//Function to return the previous day
{
    if (dayNumber == 0)
        return days[6];
    return days[dayNumber - 1];  
}
string dayType::newDay(int numOfDays)//Function to return future day based on number of days given
{
    int x = numOfDays + dayNumber;
    numOfDays = x % 7;
    return days[numOfDays];
}
dayType::dayType(string day)//constructor that gets the current day and sets the day number and initializes days array
{
   currentDay = day;
   
   if (currentDay == "Sunday")
   {
       dayNumber = 0;
   }
   else if (currentDay == "Monday")
   {
       dayNumber = 1;
   }
   else if (currentDay == "Tuesday")
   {
       dayNumber = 2;
   }
   else if (currentDay == "Wednesday")
   {
       dayNumber = 3;
   }
   else if (currentDay == "Thursday")
   {
       dayNumber = 4;
   } 
   else if (currentDay == "Friday")
   {
       dayNumber = 5;
   } 
   else if (currentDay == "Saturday")
   {
       dayNumber = 6;
   }
   
   days[0] = "Sunday";
   days[1] = "Monday";
   days[2] = "Tuesday";
   days[3] = "Wednesday";
   days[4] = "Thursday";
   days[5] = "Friday";
   days[6] = "Saturday";                     
}

dayType.cpp

#include <iostream> //import header files including dayType
#include <string>
#include "dayType.h" 

using namespace std;

int main() 
{
    dayType myDay("Monday"); //Set myDay to Monday
    dayType temp("Sunday"); //Set temp to Sunday
    dayType anotherDay("Tuesday"); //Set anotherDay to Tuesday

    cout << "My day = "; //Print myDay with the print function
    myDay.print();
    cout << endl;
    
    //Print the previous day with the prevDay function
    cout << "The day before my day = " << myDay.prevDay() << endl;
    //Print the next day with the nextDay function
    cout << "The day after my day = " << myDay.nextDay() << endl;
    //Print temp day with the print function
    cout << "Temp day = ";
    temp.print();
    cout << endl;
    
    //Print the previous day with the prevDay function
    cout << "The day before temp day = " << temp.prevDay() << endl;
    //Print the next day with the nextDay function
    cout << "The day after temp day = " << temp.nextDay() << endl;
    //Print the current day of another day with the returnDay function
    cout << "The returned day of another day = " << anotherDay.returnDay() << endl;
    //Print the day that is a certain specified number of days in the future 
    //as a parameter with the newDay function
    cout << "13 days after another day is a " << anotherDay.newDay(13);
    
    system("PAUSE");
    return 0;
}

What commands are you using?

[stickfigure02]

I was trying to compile through VC++

[Moschops]

If it compiles, then it is being made into an object file at some point.

Do you mean you want a library?

[stickfigure02]

It wont compile though and I dont know why. Here is the error:

c:\program files\microsoft visual studio 9.0\vc\include\xlocnum(135) : error C2857: '#include' statement specified with the /Ycstdafx.h command-line option was not found in the source file

Is it some setting within VC++?

Hey there.

I'm a UAT student studying for my bachelor's in Computer Science. I copied your files and ran them in my editor (I used NetBeans 7.0) and it ran just fine. I checked the error online and came across this page at MSDN that discussed manually configuring the compiler option in the Visual Studio development environment.

Try this. Hopefully this will fix things.

Good Luck,
Damita Sexton

Damita - That link was exactly what I needed. I had to go into both .cpp files and fix the file name of the .h file which was set to the default. Kind of a weird setup but ended up being a VC++ thing. Pretty easy fix in the end. Thanks!
