Managed C++ was the precursor to C++/CLI. It's still in use, but for new code you should be using C++/CLI as it's vastly improved.

It's not that bad... :-/

>printf(head->data);
printf takes a string as the first argument, not an integer. You probably just forgot to add the format string, which would make the line look like this:

printf("%d\n",...

>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.

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 ) ;

It's better to put the code directly in your post if it's short. The problem is that floating-point values aren't always exact, so you can't reliably test for equality. The usual fix for your problem...

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

I'd start with the fact that functions can't be nested inside of each other in C. You're also calling letter before it's declared.

>i am currently getting 3 errors
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).

Just so we're clear. :)


Sloppy code is sloppy code, regardless of whether it's spawned from negligence or ignorance.


That's a safe bet. ;)

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?

There's no way to print a binary value directly in C. You have to break the value up into bits and basically do it all manually:

#include <stdio.h>

int main ( void )
{
int x;

printf (...

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++ )
;
}
