C++ Program to Convert Temperatures from Celsius to Fahrenheit and vice versa

   #include <conio.h>
   void main()
   {
     clrscr();
     int choice;
     float ctemp,ftemp;
     cout << "1.Celsius to Fahrenheit" << endl;
     cout << "2.Fahrenheit to Celsius" << endl;
     cout << "Choose between 1 & 2 : " << endl;
     cin>>choice;
     if (choice==1)
     {
       cout << "Enter the temperature in Celsius : " << endl;
       cin>>ctemp;
       ftemp=(1.8*ctemp)+32;
       cout << "Temperature in Fahrenheit = " << ftemp << endl;
     }
     else

       cin>>ftemp;
       ctemp=(ftemp-32)/1.8;
       cout << "Temperature in Celsius = " << ctemp << endl;
