Help with referencing

I am getting an error message when trying to run this program using a Visual C++ 6.0 compiler. The header and code is straight out of the book and I need to understand why I am getting this error message.....maybe I am not compiling correctly? Any help please.?

This is the header file correct?

Code:

// Fig. 6.18: time3.h 
// Declaration of class Time. 
// Member functions defined in time3.cpp 

// prevent multiple inclusions of header file 
#ifndef TIME3_H  
#define TIME3_H 

class Time { 

public: 
   Time( int = 0, int = 0, int = 0 );  // default constructor 

   // set functions 
   void setTime( int, int, int );  // set hour, minute, second 
   void setHour( int );   // set hour 
   void setMinute( int ); // set minute 
   void setSecond( int ); // set second 

   // get functions 
   int getHour();         // return hour 
   int getMinute();       // return minute 
   int getSecond();       // return second 

   void printUniversal(); // output universal-time format 
   void printStandard();  // output standard-time format 

private: 
   int hour;              // 0 - 23 (24-hour clock format) 
   int minute;            // 0 - 59 
   int second;            // 0 - 59 

}; // end clas Time 

#endif

This is the source code correct?

Code:

// Fig. 6.20: fig06_20.cpp 
// Demonstrating the Time class set and get functions 
#include <iostream> 

using std::cout; 
using std::endl; 

// include definition of class Time from time3.h 
#include "time3.h" 

void incrementMinutes( Time &, const int );  // prototype 

int main() 
{ 
   Time t;              // create Time object 

   // set time using individual set functions 
   t.setHour( 17 );     // set hour to valid value 
   t.setMinute( 34 );   // set minute to valid value 
   t.setSecond( 25 );   // set second to valid value 

   // use get functions to obtain hour, miunute and second 
   cout << "Result of setting all valid values:\n" 
        << "  Hour: " << t.getHour() 
        << "  Minute: " << t.getMinute() 
        << "  Second: " << t.getSecond(); 

   // set time using individual set functions 
   t.setHour( 234 );    // invalid hour set to 0 
   t.setMinute( 43 );   // set minute to valid value 
   t.setSecond( 6373 ); // invalid second set to 0 

   // display hour, minute and second after setting 
   // invalid hour and second values 
   cout << "\n\nResult of attempting to set invalid hour and" 
        << " second:\n  Hour: " << t.getHour() 
        << "  Minute: " << t.getMinute() 
        << "  Second: " << t.getSecond() << "\n\n"; 

   t.setTime( 11, 58, 0 );    // set time 
   incrementMinutes( t, 3 );  // increment t's minute by 3 

   return 0; 

} // end main 

// add specified number of minutes to a Time object 
void incrementMinutes( Time &tt, const int count ) 
{ 
   cout << "Incrementing minute " << count 
        << " times:\nStart time: "; 
   tt.printStandard(); 

   for ( int i = 0; i < count; i++ ) { 
      tt.setMinute( ( tt.getMinute() + 1 ) % 60 );  

      if ( tt.getMinute() == 0 ) 
         tt.setHour( ( tt.getHour() + 1 ) % 24 ); 

      cout << "\nminute + 1: "; 
      tt.printStandard(); 

   } // end for 

   cout << endl; 

} // end function incrementMinutes

Either way I get the same fatal error that #include “time3.h” is a problem. What am I doing wrong?

Possibly the place where MSC++ points too to look for headers? Make sure it has the path to look for headers where the custom header is.

I got a whole bunch of linker errors when i tried it is that what your getting because if it is. It's because the functions that you are using have not been implimented just prototyped

These are two examples out of my textbook that produce output. For my homework I have to change the first part to do something else, so I figured I would see how the example works from the book.

The way I understand it from the example is that the custom header is the first part. and the error I keep getting is on the path part. (according to the pseudocode saying that it is the path)

I got the linker errors also at first because I didnt open the c++ program as a Windows 32 Console application. When I closed it and reopened it it only gave me my above error.

Hold on. Now when I tried to restart my program I saw the choice of a file that supports MSC. What is MSC and could this be the problem?

No what im saying is where are the functions defined at i don't see it unless im being blind. The things that do this

Code:

void time::setHour(int)
{
  //blah
}

when running the program this is the error message I get

c:\program files\microsoft visual studio\myprojects\pooeo\hss.cpp(43) : fatal error C1083: Cannot open include file: 'time3.h': No such file or directory

Is time3.h in the same directory as hss.cpp? cause that will throw vc++ off

I guess I dont understand directories. Ive tried it with the whole program in one C++ Source File...Build....same message. I have also tried it by putting the first part in a C++ Header File and then open a C++ Source file and place the second part in it.....same message. How do I put it in a different directory?

ok try this
File->New->Win32 Console(Test)->Empty Project->Finish
File->New->c/c++ header file(Test)
File->New->c++ source file(Test)
copy time3.h into test.h
copy hss.cpp into test.cpp

copy time3.h into test.h

did it......got the same message

can you post the whole error output for me?

bman - does vc++ have a place to add directories to look for for include files(as does dev-c++)
