Write a Program to convert the temperature in C++

Algorithm: Temperature Conversion

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

1. Start

2. Input Temperature in Fahrenheit in F variable.

3. Calculate Centigrade C = (F-32) x 5.0 / 9.0

5. Stop

Celsius to Fahrenheit

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:

Fahrenheit to Celsius

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:
