Question

program that gives the user the option of converting Fahrenheit to Celsius or Celsius to Fahrenheit. Then carry out the conversion. Use floating-point numbers. Interaction with the program might look like this: Type 1 to convert Fahrenheit to Celsius, 2 to convert Celsius to Fahrenheit: 1 Enter temperature in Fahrenheit: 70 In Celsius that’s 21.111111

Answer 1

Answer:

#include<iostream.h>

#include<conio.h>

#include<iomanip.h>

#include<stdlib.h>

void main()

{

int x;

double c,f;

while(1)

{

cout<<"\n1. For Celsius To Fahrenheit. \n";

cout<<"2. For Fahrenheit To Celsius. \n";

cout<<"3. For Exit\n\n";

cout<<"Enter Your Choice \n ";

cin>>x;

switch(x)

{

case 1:

cout<<"\nEnter The Temperature In Celsius\n";

cin>>c;

f=(c*9/5)+32;

cout<<"\nTemperature In Fahrenheit Is = "<<f

;

break;

case 2:

cout<<"\nEnter The Temperature In Fahrenheit\n";

cin>>f;

c=(f-32)*5/9;

cout<<"\nTemperature In Celsius Is = "<<c ;

break;

case 3:

cout<<"Process Completed...";

exit(1);

default:

cout<<"\nEnter The Right Choice \n";

break;

} }

}

Answer 2

This program is in Java and I have Double because it has a wider range. I have also added all the possible outputs ^_^

import java.util.Scanner;

public class CelciusToFahrenheit{

   public static void main (String [] args){

       Scanner sc = new Scanner(System.in);

       System.out.println("Press 0 for Celcius to Fahrenheit and 1 for Vice-Versa");

       double choice = sc.nextDouble();

       if (choice == 0){

           System.out.print("Enter the temperature in Celcius: ");

           double tempC = sc.nextDouble();

           double tempF = (tempC*1.8) + 32;

           System.out.println("The temperature in Fahrenheit: " + tempF + "°F");}

       if (choice == 1){

           System.out.print("Enter the temperature in Fahrenheit: ");

           double tempF = sc.nextDouble();

           double tempC = (tempF - 32)/1.8;

           System.out.println("The temperature in Celcius: " + tempC + "°C");}

       if (choice != 0 && choice != 1)

       System.out.println("Enter only 1 or 2 :(");

   }

}

Output:

(i)

Press 1 for Celcius to Fahrenheit and 2 for Vice-Versa

123

Enter only 1 or 2 :(

(ii)

Press 1 for Celcius to Fahrenheit and 2 for Vice-Versa

1

Enter the temperature in Celcius: 37

The temperature in Fahrenheit: 98.60000000000001°F

(iii)

Press 1 for Celcius to Fahrenheit and 2 for Vice-Versa

2

Enter the temperature in Fahrenheit: 98.6

The temperature in Celcius: 36.99999999999999°C
