Suggestions / Comments Apreciated!

Actually, I just think you're stupid and agreeing with iago. It's generally shit, and thanks again, iago (*grins*) for bringing that up again. With a few edits of that calculator (bad coding, like recursing main and the array usage which I don't actually mind doing in such an insignificant application) and it's fine. :)

Edit: Your calculator is no better than someone elses who is starting out in C++. Oh yeah, and you might want to use ANSI C++ :)

And lol @ you replying so fast. I was going to aim you soon, but I was eating pizza :(

Pizza > Mephisto

My Second Application:

[code]

#include <iostream.h>

int main()
{
   char indicator = 'n';
int value = 0;
double f = 0;

do
{
cout << endl << "Enter value: ";
cin >> value;

    f=1;

for(int i = 2; i<=value; i++)
f *= i;

cout << value << "! is " << f;

cout << endl << "Do you want to enter another value (y or n)? ";
cin >> indicator;

} while((indicator=='y') || (indicator=='Y'));

return 0;
}

[/code]

Maybe you should use contemporary ANSI C++ :)

Also, your indents are inconsistant. Should generally always use a 4-space tab. Some people like to use 3-space tabs and 2-space tabs when indenting their conditional statements.

Eh.. it looks correct in vc++, it fucks up when i use code tags ;O

another program:

[code]

#include <iostream.h>

int main(void)
{
   int f = 0, c = 0, type = 0;
   char indicator = 'n';

   do
   {
      cout << "1) Farenheit to Celcius" << endl
         << "2) Celcius to Farenheit" << endl
         << endl << "What do you want to convert? ";

      cin >> type;

      if(type == 1)
      {
         cout << endl << "Enter Temperature in Farenheit: ";
         cin >> f;
         cout << "Temperature: " << (f/1.8) - 32 << " Celcius" << endl;
      }
      else if(type == 2)
      {
         cout << endl << "Enter Temperature in Celcius: ";
         cin >> c;
         cout << "Temperature: " << (1.8*c) + 32 << " Farenheit" << endl;
      }

      cout << "Do you want to enter another value (y or n)? ";
      cin >> indicator;

   } while((indicator=='y' || indicator=='Y'));

   return 0;
}

[/code]

I wouldn't multiply floats by ints unless there's a special reason to.

i.e., instead of doing (1.8*c), you're better off doing (9*c)/5.
And instead of (f/1.8), use (5*f)/9.

Why do you have such a problem using up-to-date ANSI C++? :(

Hmm, I was always told (and thought) that <iostream> was up-to-date on ANSI standards with the usage of the std namespace, as where <iostream.h> was old ANSI C++.

Absolutely. Meanwhile, you could suggest how to do it anyway in the language he has chosen. There may be other reasons why someone is stuck with a particular language for the project, so just telling them to switch is not necessarily constructive.

Ooh, BURN.

He apparently wants to make lots of money and have a good life, big house, giant yard, wife with big titties and great legs, a home theatre, pool, etc.

I know this to be true because otherwise he would be using Linux.

Grok, you know me, I'm anti-Linux for the desktop, and I think ASP.NET is cool.

I tried this program out and I noticed that when you divide a smaller number by a bigger number you get 0. I then changed it to "float number1" and "float number2" and I got a more correct result. I don't know if this has been mentioned, but that is just something I found. Even thought this is an old post, you still may care.

It depends on the kind of precision the project requires. When working with floats, you tend to incur an exponentially larger delay in calculation processing. That is, floating-point arithmetic is SLOW SLOW SLOW compared to integer arithmetic.

You're going to tell me that dividing two 8-byte double-precision numbers is the same speed as integer division? Not on your life! One division might not matter, but several million would!

[/quote]It's a comparable speed. Then again, it depends on the processor. On some, floating point arithmetic can actually be faster. In any case, it does not "tend to incur an exponentially larger delay", as you claim.

In VS.NET 2003 aren't there performance options to enhance performance for integer/floating-point arithmetic? And isn't that implied on optimizations for Pentium 4/AMD processors; I saw an article about it from Microsoft explaining that that particular optimization enhances speed for artihmetic for those processors by using different instructions.
