Fahenhieght?

I'm makeing a converter, but it wont compile

Code:

---

#include <iostream>

int far ( int x )
{
 return (x-32)*(5/9);
}

int cel ( int x )
{
 return x+32*(9/5);
}

using namespace std;

int faren();

int cels();

int main ()
{
  int input;
 
  cout<<"1. Celsius to Fahrenheit\n";
  cout<<"2. Fahrenheit to Celsius\n";
  cout<<"Selection: ";
  cin>> input;
  switch ( input ) {
  case 1:           
    cels();
    break;
  case 2:           
    faren();
    break;
  default:           
    cout<<"Error\n";
    break;
  }

int faren {
 
  int x; 
  cout << "Temperature Farenhieht:";
  cin>> x;
  cin.ignore();
  cout << "Celsius:" << far(x);
  cin.get();
  }
 
int cels(){
  int x; 
  cout << "Temperature Celsius:";
  cin>> x;
  cin.ignore();
  cout << "Fahrenheit:" << cel (x);
  cin.get();
  }

Someone tell me what's wrong!

what are your errors?

You forgot to close int main()
}

Clear result of the weird indentation. Always have opening and closing braces of blocks at the same indent level, unless the opening brace is at the end of a line. In that case, have the closing one at the level of that line.

And btw. to get from Celcius to Fahrenheit the algorithm is " Fahrenheit = ((Celcius*1.8)+32), that why 0 Celcius is 32 Fehrenheit.
If you have to get Celcius, just solve Celcius in the equation above. :)

The equations 5 / 9 which will always result in zero, and 9 / 5 will also produce undesirable results. The compiler identifies them as integers. Change them to floating point numbers 5.0 / 9.0 to get the proper results.

And close int main().. LOL

I got it!!!!!!!!!

Code:

---

#include <iostream>

float far ( float x )
{
 return (x-32)*(5.0/9.0);
}

float cel ( float x )
{
 return (x*1.8)+32;
}

using namespace std;

int faren();

int cels();

int main ()
{
  int input;
 
  cout<<"1. Celsius to Fahrenheit\n";
  cout<<"2. Fahrenheit to Celsius\n";
  cout<<"Selection: ";
  cin>> input;
  switch ( input ) {
  case 1:           
    cels();
    break;
  case 2:           
    faren();
    break;
  default:           
    cout<<"Error\n";
    break;
  }
}

int faren() {
 
  float x; 
  cout << "Temperature Farenhieht:";
  cin >> x;
  cin.ignore();
  cout << "Celsius:" << far(x);
  cin.get();
 
int input2;
cout<<"Start over 1.yes / 2.no :\n";
  cin>> input2;
  switch ( input2 ) {
  case 1:           
    main();
    break;
  case 2:           
    cout:"/n";
    break;
  default:           
    cout<<"Error\n";
    break;
  }
}
 
int cels(){
 
  float x; 
  cout << "Temperature Celsius:";
  cin>> x;
  cin.ignore();
  cout << "Fahrenheit:" << cel (x);
  cin.get();
 int input3;
  cout<<"Start over 1.yes / 2.no :\n";
  cin>> input3;
  switch ( input3 ) {
  case 1:           
    main();
    break;
  case 2:           
    cout:"/n";
    break;
  default:           
    cout<<"Error\n";
    break;
  }
 }

I know its a bit messy, but it works!

BTW, a big temperature converter is the only finished part of my tutorial. (Don't view with IE!)
