Question

: Using SELECT CASE write a menu-driven program in QBASIC to convert temperature from Fahrenheit to Celsius and vice versa. For an incorrect choice, an appropriate error message should be displayed in QBASIC.
Give answer if you know otherwise your answer will be reported ​

Answer 1

Answer:

import java.util.Scanner; public class KboatTemperature { public static void main(String args[]) { Scanner in = new Scanner(System.in); System.out.println("Type 1 to convert from Fahrenheit to Celsius"); System.out.println("Type 2 to convert from Celsius to Fahrenheit"); int choice = in.nextInt(); double ft = 0.0, ct = 0.0; switch (choice) { case 1: System.out.print("Enter temperature in Fahrenheit: "); ft = in.nextDouble(); ct = 5 / 9.0 * (ft - 32); System.out.println("Temperature in Celsius: " + ct); break; case 2: System.out.print("Enter temperature in Celsius: "); ct = in.nextDouble(); ft = 1.8 * ct + 32; System.out.println("Temperature in Fahrenheit: " + ft); break; default: System.out.println("Incorrect Choice"); break; } } }

Answer 2

Answer:

import java.util.Scanner ; public class KboatTemperature { public static void main ( String args [ ] ) { Scanner in = new Scanner ( System.in ) ; System.out.println ( " Type 1 to convert from Fahrenheit to Celsius " ) ; System.out.println ( " Type 2 to convert from Celsius to Fahrenheit " ) ; int choice = in.nextInt ( ) ; double ft = 0.0 , ct = 0.0 ; switch ( choice ) { case 1 : System.out.print ( " Enter temperature in Fahrenheit : " ) ; ft = in.nextDouble ( ) ; ct = 5 / 9.0 * ( ft - 32 ) ; System.out.println ( " Temperature in Celsius : " + ct ) ; break ; case 2 : System.out.print ( " Enter temperature in Celsius : " ) ; ct = in.nextDouble ( ) ; ft = 1.8 * ct + 32 ; System.out.println ( " Temperature in Fahrenheit : " + ft ) ; break ; default : System.out.println ( " Incorrect Choice " ) ; break ; } } }
