Science: Wind-Chill Temperature
The code has been modified slightly and now uploaded to the site.

217.cpp
#include <iostream>
#include <math.h>
using namespace std;
int main(){
double twc;
double fahrenheit;
double mph;
std::cout << "Enter the temperature in Fahrenheit: \n";
std::cin >> fahrenheit;
std::cout << "Enter the wind speed in miles per hour: \n";
std::cin >> mph;
twc = 35.74 + (0.6215 * fahrenheit) - 35.75 * (pow(mph, 0.16)) + 0.4275 * fahrenheit * (pow(mph, 0.16));
std::cout << "The wind chill index is " << twc;
}
