Temperature Conversion Program - Still a Rookie

[AsheeG87]

Hey Everyone~
I'm still a C++ Rookie so please bear with me on this.
I'm doing a temperature conversion program with prototype functions.
Basicly, I was wondering if some of you would take a look at my code
and critique it for me. I'm mostly concerned with how prototype
functions work and if I designed them correctly in my code.
Your participation would be greatly appreciated!

My Code:

#include "stdafx.h"
#include <iostream>
#include <cstdlib>

double FahrenheittoCel sius(double)= 0.0; //Function Prototype
double CelsiustoFahren heit(double)= 0.0;

int _tmain(int argc, _TCHAR* argv[])
{
double tempFahrenheit, tempCelsius;
double temp;
char f;
char c;
cout << " Enter the Temperature: "; //Prompt user to enter temp
cin >temp;
cout << " Fahrenheit or Celsius?"; // If user does not specify f or c
ask them
if (temp == f)
{
c = FahrenheittoCel sius;
cout << f " degrees Fahrenheit is" c " degrees celsius ";
cout << " Continue? ";

else
f = CelsiustoFahren heit;
cout << c " degrees Celsius is " f " degrees Fahrenheit ";
cout << " Continue? ";

}
return temp;
}
double FahrenheitoCels ius (double f)
{
return (f - 32) * (5.0/9);
}
double CelsiustoFahren heit (double c)
{
return (9/5.0 * c) + 32;
}

Please fix this - it's a pain to have to keep manually trimming your
signature.

Heh, I was going to mention that as well. James, your .sig separator is
missing a character. It should be "-- " (dash dash space).

Thank you guys!
Your criticism and suggestions helped me! I appreciate you guys taking
the time to critique me! I got it to work finally!

And I found this funny....
"He made no mention of a complier, just that the code wouldn't
compile
without it. On my system, it won't compile with it!

Hahaha...I'm a girl. So..."She made no mention....". ;) Just thought
I'd let ya know Ian!

But, again, I appreciate all of your help!

So, here is the final code:
// Temperature.cpp : Defines the entry point for the console
application.
//
#include "stdafx.h"
#include <iostream>
using namespace std;

float FahrenheittoCel sius(float f); //Function Prototype
float CelsiustoFahren heit(float c);
float result = 0;
int main()
{
float tempFahrenheit = 0;
float tempCelsius = 0;
float temp = 0;
char corf = 'f';
char yorn = 'y';

cout << " Enter the Temperature: "; //Prompt user to enter temp
cin >temp;
cout << " Fahrenheit or Celsius? ";
cin >corf;
if (corf == 'f')
{
FahrenheittoCel sius(temp);
cout << temp << " degrees Fahrenheit is" << result << " degrees
celsius " << endl;
}
else if (corf == 'c')
{
CelsiustoFahren heit(temp);
cout << temp << " degrees Celsius is " << result << " degrees
Fahrenheit" << endl;
}

cout << " Continue? Y or N ";
cin >yorn;
while (yorn == 'y')
{
cout << " Enter the Temperature: "; //Prompt user to enter temp
cin >temp;
cout << " Fahrenheit or Celsius? ";
cin >corf;

if (corf == 'f')
{
FahrenheittoCel sius(temp);
cout << temp << " degrees Fahrenheit is" << result << " degrees
celsius " << endl;
}
else if (corf == 'c')
{
CelsiustoFahren heit(temp);
cout << temp << " degrees Celsius is " << result << " degrees
Fahrenheit" << endl;
}
cout << " Continue? Y or N ";
cin >yorn;
}

while (yorn != 'n')

return 0;
}
float FahrenheittoCel sius (float f)
{
result = 5.0 / 9.0 * (f - 32);
return result;
}
float CelsiustoFahren heit (float c)
{
result = (9.0 / 5.0 * c) + 32;
return result;
}
