C++ program to convert the temperature from Fahrenheit to Celsius using class

Given the temperature in Fahrenheit, we have to change it to Celsius using the class and object approach.

Input:
Enter Temperature in Fahrenheit: 109.4

Output:
Temperature in Celsius : 43

C++ code to convert the temperature from Fahrenheit to Celsius using class and object approach

#include <iostream>
using namespace std;

// create a class
class FahrenheitToCelsius {
  // private data member
 private:
  float fahrenheit;

  // public functions
 public:
  // getTemperature() function to get the Temperature
  void getTemperature() {
    cout << "Enter Temperature in Fahrenheit:";
    cin >> fahrenheit;
  }

  // FToC() function to convert the temperature
  double FToC() {
    // initialising float type variables to perform operations
    float celsius;

    celsius = (fahrenheit - 32) * 5 / 9;

    // returning the converted temperature
    return celsius;
  }
};

int main() {
  // create a object
  FahrenheitToCelsius F;

  // float type variable to store the converted temperature
  float temperature;

  // function is called by the object to store the temperature
  F.getTemperature();

  // FToC() function to convert the temperature
  temperature = F.FToC();

  cout << "Temperature in Celsius :" << temperature;

  return 0;
}

Output:

Enter Temperature in Fahrenheit:208.4
Temperature in Celsius:98

Explanation:

In the above code, we have created a class FahrenheitToCelsius, one float type data member fahrenheit to store the temperature in fahrenheit, and public member functions getTemperature() and FToC() to store and convert the given temperature.

In the main() function, we are creating an object F of class FahrenheitToCelsius, reading the temperature by the user using function getTemperature() , and finally calling the FToC() member function to convert the given temperature from Fahrenheit to Celsius. The FToC() function contains the logic to convert the given temperature from Fahrenheit to Celsius and printing the result.
