    Question 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!

    You forgot to close int main()
    }
    Sorry for spelling errors, not English!

    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.

    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!)
