Temperature
// This program asks the user for a Fahrenheit temperature, // converts the given temperature to Celsius, // and displays the results. // // References: // https://www.mathsisfun.com/temperature-conversion.html // https://en.wikibooks.org/wiki/C%2B%2B_Programming #include <iostream> using namespace std; double getFahrenheit(); double calculateCelsius(double); void displayResult(double, double); int main() { double fahrenheit; double celsius; fahrenheit = getFahrenheit(); celsius = calculateCelsius(fahrenheit); displayResult(fahrenheit, celsius); return 0; } double getFahrenheit() { double fahrenheit; cout << "Enter Fahrenheit temperature:" << endl; cin >> fahrenheit; return fahrenheit; } double calculateCelsius(double fahrenheit) { double celsius; celsius = (fahrenheit - 32) * 5 / 9; return celsius; } void displayResult(double fahrenheit, double celsius) { cout << fahrenheit << "° Fahrenheit is " << celsius << "° Celsius" << endl; }
Output
Enter Fahrenheit temperature: 100 100° Fahrenheit is 37.7778° Celsius
