Write a Program to convert the temperature in C++

Algorithm: Temperature Conversion

This algorithm inputs a temperature in Fahrenheit and converts into centigrade.

Code:

#include<iostream>
 using namespace std;
 
 int main()
 {
  float fahrenheit, celsius;
 
  cout << "Enter the temperature : ";
  cin >> celsius;
  fahrenheit = (celsius * 9.0) / 5.0 + 32;
  cout << "The temperature in Celsius : " << celsius << endl;
  cout << "The temperature in Fahrenheit : " << fahrenheit << endl;
  return 0;
 }

Output:

Code:

#include <iostream>
 
  double fahrenheitToCelsius(double fahrenheit)
  {
  double celsius;
 
  celsius = (fahrenheit - 32.0) * 5.0 / 9.0;
  return celsius;
  }
 
  int main()
  {
  double fahrenheit;
 
  std::cout << "Enter temperature in fahrenheit (in degrees) ";
  std::cin >> fahrenheit;
  std::cout << "Temperature in Celsius (in degrees) = "
  << fahrenheitToCelsius(fahrenheit) << std::endl;
  }

Output:
