Congratulations Lardmeister for that achievement :) Well done!

Depending on the compiler you are using you need to install the redistributable files that are found in your compiler's install directory. For examp VC++ 2008 Express files on my computer are here: D:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT

Apparently you are using an earlier version of the compiler. Copy those files into the c:\windows\system32 directory or some other directory that's in the PATH environment virable folders. Make sure not to overwrite files by the same name that's already in that directory because it might cause problems with other programs.

In order to learn how to program you first need to learn how to read. Please read my previous very very carefully and you will find the answer to your problem.

>>except at the end the program is bombing out
Don't know -- probably something else in your program. Did you declare temp variable big enough to hold all the characters in that string ?

>>if (size == 1 )
Why that condition? Just delete the loop and do it like this, unless of course there is other code within that loop that you haven't posted.

strcpy(temp,pOutData[1]);
	//printf("Temp = %s\n", temp);
	ptoken = strtok(temp, ";" );
	while( ptoken != NULL )
	{
   	     printf ("Results 2nd:%s\n", pOutData[1] );	
  	     printf ("ptoken:%s\n", ptoken );	
	     ptoken = strtok(NULL, ";" );
	}

Good luck with that tutorial :) Glad to have you here at DaniWeb. I took a COBOL class once in college -- hated it.

But it is a little difficult to learn -- I'd suggest you start with Dev-C++ until you get your feet wet. There are several other free compilers too.

If you are interested in books then read one of the Read Me threads at the top of this board. It contains a lot of suggestions.

I would copy the string into some local buffer because strtok() will replace the ; with null characters, which destroys the original string.

char temp[255];
strcpy(temp,*pOutData);
pToke = strtok(temp,",");
// rest of program here

tutorial here

This is complicated programming and you need to have a good understanding of C or C++ programming. Not a task for beginners.

pOutData appears to be a pointer to a pointer or a 2d array of strings, like argv parameter to main() In either event line 5 can not work because strtok() only works with 1d character arrays. pOutData needs to be a pointer that is declared similar to the way you declared pToken

>>strcpy(input,line);
What's the initial value of i? Answer: undefined because you didn't set it to 0 before that loop started.

>> while (line!=EOF)
line will NEVER EVER be EOF. So that's the wrong way to code that loop. What you need to do is create another integer that counts the number of lines read so that in this loop you can check the number of lines. You have already done that to an extent -- in the loop that reads the data you are using variable i but then the program uses that same variable over again. Use a different counter. for(i = 0; i < counter; i++)

Can't speak for others but those kind of ads don't bother me at all and I'll occasionally click on one to see what its about. I don't have any clues about your other questions.

Do you mean you deleted c:\temp ? Very Very bad thing to do because many other programs use that too for storing temporary files. Re-create that folder and the compiler will be happy.

It you check the environment settings you will probably find one called TEMP=c:\temp. That's what programs look at to find out where the temp directory is located. If you delete that folder without making changes to the TEMP environment setting your computer will be in big big trouble.

for( i = 25; i >= 1; i--) Check that i is greater than 1. In your code 25 will always be greater than i because i starts out at 25 and goes down from there.

Start at the top of the list you posted and do them just one at a time. Don't attempt to do them all at once. Do the first requirement then compile, correct bugs, and compile again until all problems have been fixed. Only then do you begin the next statement.

Maybe you should use a different compiler -- there are several free ones, such as Dev-C++ and VC++ 2008 Express.

Here is a nice tutorial that lots of people use.

post questions in the language of your choice, such as C, C++, C#, VB, etc.

Hi Ancient Dragon,

. Can you guys tell me how can I make my contribution (donate some money) to this site???:)

Beast Regards,

gazoo

Scroll up to the very top of this page and you will see "DONATE" link on the very top line. You get other benefints for donating too, such as no ads.

stop using inlinecode and adding your own color tags. It makes it very difficult to copy/paste into my own compiler. Use standard code tags and your program will be color coded.

First I would create a structure (or class if you like) to contain all the information for one company. Change the function to accept a reference to a vector of structures instead of all those string arrays. That will simplify your intire program.

struct company
{
    string companyName;
    string something; // e.g. A123, whatever that represents
    string somethingElse // e.g. case
    // etc. etc for each of the other fields
};

// create an array to hold the structures
long readFile (vector<company>& colist)
{
    // now read the data
    struct company co;
    while( getline(fin,co.company) )
    {
       getline(fin,co.something);
       getline(fin,co.somethingElse);
       // etc for each field
       //
       // finally put co into the vector
       colist.push_back(co);
    }
}

delete lines 9 and 10 because that doesn't work, and replace it with just this one line typedef Contribution BigSpender[MAX];

>>But know how I can access to my values in array
Is that the question -- how to extract each of the numbers in the string ? extract them using sscanf(). There is a simple example

int main()
{
    char line[] = "123 234.56 789";
    int a, b;
    float c;
    sscanf(line,"%d %f %d", &a, &c, &b);
    printf("%d %f %d", a, c, b);
}

>>This is the first question I have, does that mean studentType is the base class or persoType is the base class?
personType is the base class.

>>cout << studentList[count].getFirstName
getFirstName is a function, so you need parentheses just like calling any other function cout << studentList[count].getFirstName() Same with getLastName -- use parentheses as above.

There are two versions of getline() -- cin.getline() is for character arrays and getline(cin,...) if for std::strings.

You didn't say how the data file is formatted, so I just assumed it has all the information on one line because you said you wanted to use getline(). Post a few lines of the data file so that we can see how it should be read.

Yes because they will contain no windows-specific function calls. You should be able to port it to *nix version of QT without any code changes, assuming you did not make any os-specific function calls outside what QT gives you.

Here is how to code that loop. You can delete lines 8, 10 and 19

int count = 0;

while( getline(fin, product[count]) )
    count++;

>> I wonder what's next.
According to legend Pope Benedict XVI is the last pope. The next one will be Saten himself.

struct Contribution
{
	string name;
	double amount;
};

const int MAX = 25;

typedef Contribution BigSpender[MAX];

const string NAME_FILE = "names.txt";
const string CONTRIBUTION_FILE = "slush.txt";

void InitProgram( BigSpender& ContributionRec );

int main()
{
    BigSpender ContributionRec;
	InitProgram( ContributionRec );
	return 0;
}

void InitProgram( BigSpender& ContributionRec )
{
	return;
}

>>Again, sorry it doesn't have any color, but I haven't had a chance to learn how to use that yet

Read your PMs. You have a PM that shows you how to do that. Scroll up to the very top of the page and click the PRIVATE MESSAGES link.

And re-read the code in my original post here. What you implemented is totally wrong. Paying attention to detail is required in programming.

You need to look for socket programming. Exactly how to do it depends on what operating system you are using. www.DataReel.com has a large free library that contains client/server programs among other things and is ported to both *nix and MS-Windows.

>>yes i did.
Than I guess you just ignored it because you didn't change a thing about those loops. I'm not going to try to answer your questions if you just ignore everyone's suggestions.

Repost without all those color tags and use code tags to make it readable.

Post what you have done so far to resolve this. What compiler and operating system are you using, because it will make a difference how you create the threads.

Its impossible to read that code because of all the color tags you inserted. Did you bother to read my previous post ??? (I'll bet you didn't)

I like Bud, but only after it has aged for at least 6 months. I buy a case and leave it sitting for 6 months to a year before drinking it.

Assuming we're all still here of course.

I don't know about you but I will be :)

ancient said but according to that page, he does.

That was posted before Dani and Happygeek gave me modly powers here :)

The use of num1 and num2 in lines 17 and 22 is destroying the values you entered on line 13 and 15. Use some other variables on lines 17 and 22

for (int num3 = 1; num1 <= num1; num3++)
{
       for (int num4 = 1; num4 <= num2; num4++)
       {
           cout << num3/num4 << '\t';
       }
}

Even hear of google ? If not, then you should learn to use it.

>>Is it possible to print anything on screen in C or C++ without using main().

Yes -- write a MS-Windows win32 api program which uses WinMain() instead of main(). Or use VC++ 2008 and it will generate a console program that starts with _tmain().

Read this

If you enter 2-28-2008 why do you want to display 2-29-2008 ? All you need to do is validate whether February has 28 or 29 days. If you enter 2-29-2007 then your program should display something to the effect that you entered the wrong number of days.

if( leapyear(year) && month == 2) 
{
    if( dd > months[1]+1 )
       cout << "Invalid # days\n";
}
else
{
    if( dd > months[1] )
       cout << "Invalid # days\n";
}

There is a shorter way to express the above

if( mm == 2)
{
    // if february
    int ndays = (leapyear(year) == true) ? 29 : 28;
    if( dd > ndays)
        cout << "Error\n";
}

>>..that which line in above code is assigning the values of Disk-file to the arra
line 7 infile >> sort[count] >>and secondly above code is just showing the String..its not sorting data..
All you asked was how to read the data from disk instead of from the keyboard, so that's all he posted. you already posted the sorting code on your original post. Just do what you did before.

>>Don't you think it's unfair to dismiss Knuth's counter-argument due to age yet allow the even older article to stand as a valid argument

Yes -- Dijkstra's article isn't relevent any more either :)

No one here is going to do your homework for you. Sounds like you are way over your head, so either drop the course or hit the books.

please answer for this..i iwll be very grateful to u

You didn't ask a question. All you did was dump your homework assignment here.

Sorry what is that mean??

Re-read the code you posted -- its there twice. Repost and this time preview your post before hitting the Submit button.

post code. If its reading character by character then it will pick up spaces too.

char c;
while( infile.get(c) )
{

}

I added some more to my previous post -- please re-read it for more suggestions

The code you posted isn't very useful. Check for missing semicolons, especially at the end of the class declaration

class object
{
<snip>
};

Looks like the problem may be in the way you have the header files included.

food.h >> objects.h >> maincontrol.h >> food.h

So nothing is fully defined. Try adding class forward references.

There are many companies who have that rule as a coding standard. One way in and only one way out of a function.

you double posted the code.
