Hello,
I am having a problem with a function. I am trying to increment a variable (odometer) using the speed and distance traveled.
Below is what I have. Any suggestions are appreciated.
Thanks,
Eric
<br />
void drive( int, int );
<br />
<br />
<br />
<br />
void Car::drive( int spd, int minutes )
{<br />
int remainderMinutes = 0;<br />
int hours;<br />
int distance;<br />
<br />
system( "CLS" );<br />
<br />
while( minutes > 60 )<br />
{<br />
remainderMinutes += minutes % 60 * oneDividedBySixty;<br />
minutes += remainderMinutes;<br />
}<br />
<br />
hours = minutes * oneDividedBySixty;<br />
<br />
distance = spd * minutes;<br />
<br />
cout << "\n\n The distance is " << distance << ".";<br />
cout << "\n\n The speed is " << speed << ".";<br />
cout << "\n\n The time is " << minutes << " minutes.";<br />
}<br />
<br />
<br />
<br />
int main()<br />
{<br />
Car c;<br />
<br />
char choice;<br />
do<br />
{<br />
cout << "\n\n\n Please make a selection from the menu.\n\n";<br />
cout << "\n Press 'D' to display the car attributes.\n";<br />
cout << "\n Press 'R' to reset the car attributes.\n";<br />
cout << "\n Press 'X' to exit the program.\n";<br />
<br />
cin >> choice;<br />
choice = toupper( choice );<br />
<br />
switch( toupper( choice ) )<br />
{<br />
case 'D': c.printCar();<br />
break;<br />
<br />
case 'R': c.reset();<br />
break;<br />
<br />
case 'X': break;<br />
<br />
default: cout << "\n Unknown choice entered.\n"<br />
<< " Enter a new choice.\n\n";<br />
break;<br />
}<br />
<br />
} while ( choice != 'X' );<br />
<br />
<br />
c.reset();<br />
<br />
c.printCar();<br />
<br />
<br />
<br />
c.drive( c.getSpeed(), c.getMinutes() );<br />
<br />
<br />
<br />
cout << "\n\n\n ";<br />
<br />
return 0;<br />
<br />
}<br />

You should start by describing what your problem is.

My problem is that the remainderMinutes equation is not working correctly.
Thank you,
Eric

How did you declare (and initialize) oneDividedBySixty?

As of now, my two main concerns are:
1.) Making sure I convert the ints to floats correctly (where needed).
2.) Figuring out what is going on with my destructor (this is all new to me).
Every time I run the program with the destructor, I get an ENTERNAL COMPILER ERROR.
I really appreciate the feedback and suggestions!
Thanks,
Eric

Does anyone know what the INTERNAL COMPILER ERROR means?
<br />
--------------------Configuration: Implementation - Win32 Debug--------------------<br />
Compiling...<br />
Implementation.cpp<br />
I:\Documents and Settings\Implementation.cpp(48) : fatal error C1001: INTERNAL COMPILER ERROR<br />

I found this http://owlnext.sourceforge.net/qa51.html[^].
The site says, "This error occurs only on machines with the Windows 95 or Windows 98 operating system."
But I am running Win XP Home w/SP2.
I'm puzzled.
Thanks,
Eric

Oops, nevermind the INTERNAL COMPILER ERROR.
I forgot a set of parenthesis (see http://lithiumdata.com/QandA/compileerror.htm[^]).
Originally I had:
<br />
Car::~Car<br />
{<br />
cout << "\n\n The destructor has been called.\n\n";<br />
}<br />
Here is what it needs to be:
<br />
Car::~Car()<br />
{<br />
cout << "\n\n The destructor has been called.\n\n";<br />
}<br />
Thanks,
Eric

if i have a clistctrl on my dialog.
a variable called list is associated with it.
now, i want to add listview-groups in this list.
i try to create a PLVGROUP-structure,
but if i want to run this code, the compiler generates an error.
i can't create any PLVGROUP structure!
what do i have to do to create one? if i create
a variable of PLVGROUP, then i can access it's members, like cbSize.
but if i want to compile, it doesn't work.
can anyone help me?
(i hope you understand my bad english. im from switzerland, so i don't
know english very well  )

#include "commctrl.h"

thanks.
but it still doesn't work when i add "#include 'commctrl.h'".
and: how do i specify comctl32.dll, ver. 6 in the manifest?

LVGROUP is only for XP+ so you have to tell your compiler that you are targeting XP.
in your stdafx.h file add the following
#ifdef _WIN32_WINNT
#undef _WIN32_WINNT
#define _WIN32_WINNT 0x501 // target windows NT version 5.01 (XP)
#endif If you do not do this then the portions of commctrl.h that declares LVGROUP etc. is left out by the preprocessor.

oke, i tried to do this.
but if i compile, it still fails....
do i have to include other headers or
some libs?
i hope you can help me! thanks

"It fails" is not very discriptive. If look at the compiler output it will give you an error number (ie C####), a brief description of the error, and the line number in your files that caused the error. Look up the error number in MSDN for a better description, and possible solution for the error. Then try to fix your source file taking into account what MSDN says. If you still have troubles, then post the code here that caused the error, and the compiler output that describes the error, complete with the error number. Then maybe I can help you, but the most obvious solutions, based on the very limited info you supplied, has already been given by me and others.

I have this program I have to write for school that accepts two integers. hours and minutes. I then have to output the format in 6:00 format. I'm only allowed integer division and and modulus division. I've tried everything I can think of but my output still looks like this. 6:0 Any tips?

How about this?
int main(int argc, char* argv[])
{
int hours = 6;
int minutes = 7;
int seconds = 8;
printf("%d:%02d:%02d\n", hours, minutes, seconds);
return 0;
}
|
|
|
|
|
or, without using printf formatting trick, try this:
int main(int argc, char* argv[])
{
int hours = 6;
int minutes = 7;
printf("%d:%d%d\n", hours, minutes / 10, minutes % 10);
return 0;
}

little too advance for a student who just started learn C++ three weeks ago. Plus It has to advance the hour when the minutes go over 59. I am so stuck.
I cant even use conditional operators
Here's what I got:
#include<iostream><br />
#include<iomanip><br />
using namespace std;<br />
<br />
<br />
int main()<br />
<br />
{<br />
int hours, minutes ;<br />
<br />
<br />
cout << "Input the time as hours and minutes (e.g. 5 23 means 5:23) " ;<br />
<br />
cin >> hours >> minutes ;<br />
<br />
const int minutes_per_hour = 59;<br />
<br />
minutes = minutes + 1;<br />
<br />
<br />
<br />
<br />
cout << " The time is: " << hours<< " :"<< setfill('0')<<setw(1) << minutes << endl ;<br />
<br />
<br />
<br />
<br />
<br />
<br />
system("pause");<br />
<br />
return 0 ;<br />
<br />
}
