There's also nothing wrong with using "else" so I'm not sure why you'd want to avoid it...

Adding elses to this code would dramatically change it's flow. Note that for n in a range (1,10) all callfuncs would be called.

Have you something personal against if-else?

Try

#define WHATEVER_YOU_LIKE_AS_IF     if
#define WHATEVER_YOU_LIKE_AS_ELSE   else

and then, for instance

WHATEVER_YOU_LIKE_AS_IF (i>0 && i<10)
//..
WHATEVER_YOU_LIKE_AS_ELSE WHATEVER_YOU_LIKE_AS_IF (i>11 && i<20)
//..
//...

You can try something like this

int func1()
{
return 0;
}
int func2()
{
return 0;
}

typedef int (*funcptr)();
struct condition
{
int low;
int high;
funcptr func;
};

condition arr[] = {
{ 10, 20, func1 },
{ 20, 30, func2 } // Can add more data here
};

int n=17;

for (int i=0;i<2;++i)
{
if (n > arr[i].low && n < arr[i].high)
{
arr[i].func();
// If you want you can break here
}
}

Thank you very much all of your response,

The approach Arun has suggested is i think the way i was looking for as best and fasted approach.

Thanks Arun to help me suggesting this approach, it's really nice and definitely fastest method uses full potential of C/C++ language.

Thanks again.

One more advantage of this method i can change limits any time at one location for any if condition.

So to change the limits i need to see only at one place.

Thanks

Hai!

Using MessageBox or AfxMessageBox we are able to display some message to the user during runtime, the message may include the value returned from a function etc.

Can we do the other way ??

I want the user should enter one byte data during run time, depending on the entered value i want to proceed my calculation .

Is it posible in MFC, if yes how to do it !!

Thanks!

So why not just create a dialog box with an edit control?

Any inbuilt messagebox !!

Instead of typing all these exclamation marks you could have already created that dialog.

hi,
I have to develop a user interface which will take an XSD file as input.I'll read this xsd file and get the elements from the xsd file and generate an xml file dynamically. also after generating the xml file i have to validate it with the xsd file. how can i achieve this....

I have thought of a solution but pls comment if it is an effecient way.

I already have a sample as to how the xml file would look. So is it fine if i generate the GUI with the controlls and allow the user to enter the datas and then parse it and generate the xml file (Statc one not a dynamic one)?? I prefer this method because in the xsd file the elements are classified as either required one or optional one... so it becomes difficult to read all the elements in the xsd and populate them as a control in the UI dynamically. Also i couldnt find any way to read the elements of an xsd file. I want only in VC++ not in any other tool (vb or .net).

Pls help

Regards
Jayaraman

Hi,

I need to take last two bytes from unsigned integer. How can i get it.

Ratheesh,

Hello Ratheesh,

You can use LOWORD()[^] macro to get the last two bytes together.

If you need last two bytes separately, then call LOWORD()[^] to get last two bytes together and then get bytes separately by calling LOBYTE()[^] and HIBYTE()[^] macros.

Regards,
Jijo.
