Answer 1

Answer:

(1) #include<iostream>

(2) #include<conio.h>

(3) using namespace std;

(4) void main()

(5) {  

(6) float temp;

(7) char sel;

(8)    cout<<“Select a temperature value in Celcius or Fahrenheit.\n”;

(9)   cout<<“Press C for Celcius.\n”;

(10)   cout<<“Press F for Fahrenheit.\n”;

(11)  cin>>sel;

(12) switch (sel)

(13){

(14)case ‘C’:

(15) cout<<“Enter a temperature value in Celcius: “;

(16)cin>>temp;

(17) if(temp<=0)

(18)   {

(19)   cout<<“Water is solid at “<<temp<<” degree C.”;

(20)   }

(21)  else if(temp>=100)

(22)   {

(23)  cout<<“Water is gaseous at “<<temp<<” degree C.”;

(24) }

(25) else

(26)    {

(27)   cout<<“Water is liquid at “<<temp<<” degree C.”;

(28)  }

(29)         break;

(30)  case ‘F’:

(31)     cout<<“Enter a temperature value in Fahrenheit: “;

(32)   cin>>temp;

(33)   if(temp<=32)

(34)  {

(35)  cout<<“Water is solid at “<<temp<<” degree F.”;

(36)    }

(37)    else if(temp>=212)

(38)  {

(39)   cout<<“Water is gaseous at “<<temp<<“degree F.”;

(40)  }

(41)    else

(42)   {

(43)  cout<<“Water is liquid at “<<temp<<” F.”;

(44)    }        

(45)    break;

(46)  }  

(47)   getch();

(48) }
