Question

Write a function that takes temperature in degrees Fahrenheit as input and returns the temperature in degree Celsius as output. Here is the signature of the function:

double toCelsius (double)

Following is the formula to convert °F to °C:

Answer 1

// include required header files

#include <iostream>

using namespace std;

// create the required function.

double toCelsius(double fahrenheit)

{

    // declare the required variable

     double celsius;

     // formula

     celsius = 5.0/9 * (fahrenheit-32);

     // return the calculated result

     return celsius;

}

//main function

int main()

{

    // required variable

     double fahrenheit;

    // Display the message

     cout << "Enter Fahrenheit temperature : ";

     // take input from user

     cin >> fahrenheit;

     // call the function and display the converted temp.

     cout << "Temperature in Celsius is : "<< toCelsius(fahrenheit) <<endl;

}
