That's waaaaaaay beyond you at the moment. Focus on learning C++ as best you can, but don't expect to be able to write an MMORPG anytime soon. You need a lot of...

Then you don't really know the theory behind it. ;) Not to be rude or anything, but these are all pretty straightforward...

Don't call toupper on every character, just on the first one:

>Not any more -- C99 has changed that for C language
While C++ has a certain measure of compatibility with C, it's with C89, not C99. In C++, array sizes must be compile-time constants.

If you understood the problem well enough to actually write this program, you wouldn't need to ask what language is best. I'll go out on a limb and say you're in over your head at present.

Really? How do you know? If you're talking about the length...

Oh, don't read it as me bashing your solution, it's the same one I'd use. I was just mentioning that little pitfall because I'd noticed it while brainstorming. :)

>but don't know how to use cast. can you help me?
That's something that any C++ book or reference will tell you how to use. It would be "cast" or "type cast" in the index.

>since its not returning anything?
I don't understand. It's clearly returning something because the code that calls the function uses the return value:

kptr = function2( n ) ;

You can't use a...

It's a hack to avoid wasting extra space on links. It takes advantage of the butterfly effect using XOR. If you take the XOR of two...

No, changing the array to static and actually using the values you've cached solved everything. If you don't to the latter, your code won't be any...

Standard C++ currently maintains compatibility with C89, not C99. So you can't use VLAs in C++

They're telling you that you can't use an array as the condition for a switch statement. You can only use integral values (or char, because char is an integral type).

>I would like to know once and for all how to convert a double to a const char*
Casting doesn't work. You're not converting the double to a string with a cast, you're telling the compiler to use the...

Do you really want to be casting away the precision when you call abs? Maybe you should be using fabs instead so that it gives you the absolute value without losing the precision.

>Is it really necessary to write your application in C or C++?
It's probably an assignment for a C++ course, so yea, I imagine it's really necessary. Why do you ask?

You can use the standard time library to do it, sort of:

#include <ctime>
#include <iostream>

void long_running_operation()
{
for ( unsigned i = 1; i != 0; i++ )
;
}

>.533 microns converted to miles per hour = 3.311908

Well, first, you need to remove the "per hour" part of that. The conversion is strictly...

It'd be 100% easier if you used the standard complex stuff from the <complex> header. Despite the name, it's actually quite...

>why does that matter anyway? i thought c++ is portable
C++ doesn't specify anything about hardware. When you step outside the bounds of the language definition, you lose the portability.

Of course it doesn't. The errors don't manifest until the int main() { line. In this case because your typedef doesn't end with...

>Any ideas on how to fix this?
Nope. Clearly you have a syntax error in scene.h, but since you didn't post the contents, it's impossible to tell you what's wrong or how to fix it.

>}else(
That last character is a paren, not an opening brace.

>default;
That last character is a semicolon, not a colon.

Damn, I'm good. cin >> n; reads an integer, but leaves a newline on the stream. getline ( cin, N ); is supposed to stop reading when it finds a newline, so it looks like the call is getting skipped....

>I have used getline() but that didn't stop the compiler to get a value..
Post a full program that has the problem. I'm guessing that you have a cin>><blah> somewhere before the getline, and the...

>void main(){
main returns int. Since you can omit the return statement in C++, using int main on top of being correct and portable actually saves you one keystroke. It's a win-win situation. :)

That's not a good description of the algorithm. :( You want to loop as long as larger is greater than zero. You want to always double smaller and halve larger, and only add smaller to the accumulator...

That's a logic error. What is "Brown's method" supposed to be doing?

>As of now, the program only prints out :"Go again?".
It shouldn't print anything. That code won't compile because the braces are mismatched and functions don't nest inside of each other. This works...

If you assign the value to an int, the fractional part is truncated. Subtract that from the original value and you get just the fractional...
