Need Help please

The question is:
Write a C++ program that will read temperature and degrees fehrenheit and convert it to degree celesius.
celesius=5/9(fahrenheit-32).
It may be very easy to other but I'm an ameature in C++.
please help :(

No one will write full code for you...show some efforts...whereever you are stuck...post it....someone will definetly help you

Well to begin with you are gonna need a function that would translate from C to F, and from C to F

and then in the main function you are gonna need to ask for the degreese and run the apropriate function.

Maybe this will help, just a few days old:

It is the reverse of your problem.

Code:

---

#include<iostream>
using namespace std;
int main()
{
  float fahr; //holds user entered degrees in Fahrenheit
  float cels; //holds our calculated degrees in Celsius

  cout << "Enter degrees in Fahrenheit: ";
  cin >> fahr;                          //Get user input
  cels = (((fahr-32)/9)*5);            //Equation to convert F to C
  cout << fahr<<" degrees equals "<< cels << " degrees in Celsius"<< endl;  //Output answer
  system("PAUSE");  //Pause so you can read the answer
  return 0;   
}

Evidently not. Please do not post questions asking for people to write your entire program. Come to the forums with a specific question and show that you have already tried. Equally annoying, do not encourage this behavior by GIVING people their entire program.

Please refer to the forum rules:

I'm sorry but it was such an easy program that explaining it is longer than writing it. I couldn't help it. I commented to show him how it was done.

What if you want to go from Cels to fah?

you can create the functions:

Code:

---

int FC(int f)
{
return (f - 32) * 5/9
}

int CF(int c)
return (c * 9/5) +32
}

He didn't say he needed to go from Celsius to Fahrenheit, but yes you could have made the equation into a function.

Thank you all for helping me out and i'm sorry that i had make go through all of this.
And by the way you are right i should specifie my question.
Anyway i only had two classes in C++ and i have no backeground on this subject.
Again thank u all for help. :)

Here is a little code you can try:

Code:

---

#include<vector>
#include<cstdlib>
#include<iomanip>
#include<iostream>
#include<windows.h>

using namespace std;

        char*  get_user_input();

        bool  again();

private:

        vector<char> user_input;
};

void clrscr();

int main()
{

        do

                f_temp = MyTemp->get_user_input();

                MyTemp->display_answer(f_temp, MyTemp->f_to_c(f_temp));

        }while(MyTemp->again());

return EXIT_SUCCESS;
}
