It would be helpful if you posted the contents of that *.cap file. The code you have posted is a bit confusing to follow, so knowing the file contents will help us help you.

does sum1 make a solution for it..???
i m wrkin on DevC++

No. We do not write your program for you, but we will help you write it yourself. Show us some effort, such as post the code you have tried, and ask specific questions about your code. But do no expect anyone here to do your homework for you, that's your job, not ours.

shadwickman is right -- we are not here to write programs for people but to help them write their own programs. You will not learn anything if all you do is copy someone else's work.

The first thing you need to do is sit down with pencil & paper and write down all the things your program needs to do. Then start writing a program that accomplishes that list, coding one small part at a time.

move lines 20, 21 and 22 up between lines 17 and 18 (outside the loop)

Its called data validation. After input the program needs to check the variable's contents for correct characters. If incorrect characters are detected then display error.

use a loop and validate user input

while(true)
{
   cout << "Enter a number\n";
   cin >> number;
   if( !cin.good() )
   {
        cin.clear();
        cin.ignore(1000,'\n');
        cout << "Error\n";
   }
   else
       break;
}

Edit: 1000th post, yay :)

Congratulations :) And keep up the good work.

Forget about VS97 and upgrade your skills before you become obsolete in the programming market. AFAIK c++ programs written with VC++ 2008 to not require the .NET framework -- its the CLR programs that require it. If you stick with ISO standard C++ and win32 api then your programs should work on older windows platforms.

One more reason to upgrade your skills is that the C++ language as evolved beyond what it was 10 to 20 years ago, and the Microsoft compiler supports the c++ standards a lot better than it did in the VC++ 6.0 and earlier versions.

As for VC97 -- it may not even run on current/future version of Windows. I have VC++ 6.0 too and it has problems running on Vista.

Why would you want to use such an old compiler? Get the newest version VC++ 2008 -- the Express edition is free., but it has its limitations, such as no support for MFC.

That cartoon is funny, but I don't get its relevance :confused:

I'm going to donate my dollar to the Peter King campaign.

Example: "g++ -o out.a main.cpp"
If you want that to be executed inside a C or C++ program: system("g++ -o out.a main.cpp");

>>cout<<sizeof(b)<<endl;
The sizeof operator (its not a function!) returns the number of bytes occupied by the object. In the case of variable b it is 6 integers and the size of one integer is 4 bytes, so simple math 6 * 4 = 24.

The second one is a little more difficult to explain. If you print out the addresses then you will see that b+0 is the same address of b, and (b+1) is the same address as b[1];

0040FCE8
sizeof(b+0) = 4 0040FCE8 0040FCE8
sizeof(b+1) = 4 0040FCF0 0040FCF0
Press any key to continue . . .

int main()
{
    int b[3][2] = {1,2,3,4,5,6};
    cout << hex << b << "\n";
    cout << "sizeof(b+0) = " << sizeof(b+0) << " " << (b+0) << " " << b << "\n";
    cout << "sizeof(b+1) = " << sizeof(b+1)  << " " << (b+1) << " " << &b[1] << "\n";
}

Using the above program you should be able to figure out the rest.

No its not photoship. After printscreen I pasted it into MS-Paint and saved it.

A Windows Hook might do it.

If you want me disprove that, send me: $40 for rolling papers, $350 for an ounce, and $200 for microbrews.

And that would only prove I'm an idiot for doing that :)

I just upgraded and I don't really see any difference, other than there is now a button to open a new tab, like IE8 has.

call clock() at the start, then again at the end, and subtract the two.

clock_t t1, t2;
t1 = clock();
// do something here
t2 = clock();
clock_t diff = t2 - t1;

I assume you mean clock() -- yes, just restart the program.

>>I can prove you wrong on that. - MosaicFuneral
Ok smartass, how can you prove that I don't know any programmers show smoke dope. And I'm not the only one who claims smoking pot and programming don't mix. Just read post #9 here -- the pot smokers flunked the programming class.

2) The computer speed has nothing to do with srand(). srand() is used to see the random number generator so that it does not generate the same set of random numbers every time you run the program.

4) We are only a little peeved at newbies who want us to do their homework for them. Show us some effort and you will get all the help you want.

If you don't want to be here why the hell are you posting ?? Just go away.

Looks like its missing a close bracket } at the last line.

What other compiler errors are you getting? What compiler and operating system are you using?

I was finally able to get that FileInfo stuff figures out, not by MSCN or google but by IntellSense. So now I can continue on with that tutorial.

When I change that I get this warning

1>cl : Command line warning D9035 : option 'clr:oldsyntax' has been deprecated and will be removed in a future release

Then get other errors, such as this one (line 19 in the code shown below).
Form1.h(22) : error C2059: syntax error : 'public'

Has anyone tried to write this tutorial using VC++ 2008 Express? The article claims to be written with VC++ 2005. But I thought 2005 and 2008 used compatible versions of CLR language. I'm getting all kinds of compiler errors -- for example String* str; instead of using String^ str; and creating objects with new instead of gcnew. The last straw for me was while attempting to implement the section concerning FileInfo class. None of the FileInfo methods Microsoft has in that article work.

read this article Seems to me it would be a whole lot easier to use managed streams. Don't ask me how because I have not done it. Something like this article.

I was a coder for over 20 years and know no one who smoked marijuana. Tobacco yes, marijuana no. And it makes sense to me -- can't program when stoned or intoxicated.

merged the two threads.

Hurrey! I finally did it :) Only took me about two years or so.

Another remark: in nearly all benchmarks, outputting an integer takes longer than a string.

That would be expected because it has to convert int to string before displaying it on the console screen.

As you can see between posts #12 and #13 speed not only is compiler dependent but also machine dependent.

But I'm surprised to see that Code::Blocks using MinGW produces faster code than VC++ 2008.

GetThreadTimes()

I have not used it and don't know if it will meet your needs. Did you overlook this thread?

I don't understand what's so difficult about thread timing. If you want the thread to quit after a specified amount of time, then just compare current time with original thread entry time and exit when that difference is greater than some pre-determined amount of time.

There is no point comparing the difference because such a comparison will be compiler dependent. How one compiler implements cout and printf might be different than how some other compiler implements them. One compiler might wrap cout with printf() while another compiler might wrap cout with win32 api function WriteFile() (in MS-Windows os), bypassing printf() altogether.

You mean like this: Color coding requires the language option in to code tags

#include <iostream>
int main()
{
   std::cout << "Hello World\n";
}

line 34 of the code you posted: In the actual function you have to give the parameter a name, such as void Calculate( double number )

pass to function: its just a parameter

int foo(int n)
{
    return n*10;
}

int main()
{
   // This line passes the value 15 to the function foo()
   // and gets the return value in the variable named x
    int x = foo(15);
}

>>Is the .exe file deployed or a library is created out of the application for deployment?

The exe. Only exe files are run on a Windows operating system -- libraries and DLLs require exe files to run them. Depending on the exe program you may also have to deploy one or more DLLs along with the exe program.

If you want the same program to run on both Windows and *nix you will have to compile them on under both operating systems -- the same binary program will not normally run on both systems. And in some cases that may require major rewrites of the program to port from one os to another.

Learn the c++ language first -- don't jump into the deep end of the pool until you know how to swim. A program like you describe will take a firm grasp of the C or C++ language (could be in other languages as well).

If that's all you have coded then forget it because your program is missing hundreds of lines of code. See this tutorial.

Its the same as any other sort algorithm -- when you need to swap just swap Person pointer in the PersonList structure.

It would be a lot easier to convert the linked list to an array of pointers into the linked list, then sort that array.

did you try my previous suggestion yet?

You can't just code random variable names and expect the program to work.

hEdit is probably a handle to a dialog boxl that must have been previously allocated. It must have been declared and initialized in your program somewhere. I suspect you should not be using hEdit because hEdit is probably an edit box control in that dialog box. Use the HWND that was returned by CreateWindow() (I think that's the function) when the dialog box was created.

You will learn a great deal more by writing it yourself instead of trying to copy someone else's work.

The problem could also be one of Endianness. The byte order on windows and *nix computers are reversed. Maybe your os is writing the bytes out in reverse order during the copy process. To test that use your system's command-line copy function to make the copy, FTP to Windows and check it with MS-Word.

What variables do you want initialized?

>>SendMessage(hwndListBox, LB_GETTEXT, a, etxt[a]);
That's not correct, the last parameter is only passing a single character, not a pointer to a character array. There is how it should be coded SendMessage(hwndListBox, LB_GETTEXT, a, etxt); If you want to keep all the strings in the list box then declare etxt as a 2d array etxt[20][255]; , which is an array of 20 strings, and each string can contain up to 255 characters. If that is what you want then you don't have to change the SendMessage() function as I previously posted.

There's a time to smile, and a time to frown. I try to smile all the time while at work as a WalMart cashier and often wear a happy-face sticker on each shirt lapel. I haven't been punched in the face yet for smiling :)
