Question

Wind Chill («F) = 35.74 +0.621 5T-35.75(V0.16) + 0.4275T(V0.16) where,T= Air Temperature (明v-wind Speed (mph) Effective 11/01/01

Part​ ​A

Write a function windChillCalculator ​to determine the wind chill. Your main function should take in user inputs for T (air temperature) and V (wind speed) and pass these values as parameters to your function. After your function calculates the wind chill it should return​ it to main. To test your code, for T = 30.0 and V = 5.0, you should get a Wind Chill of 24.7268. Within your main function, print the following cout statement: cout << "The wind chill is " << wind_chill << " degrees F." << endl; HINT​: Look at the pow()​ function in the C++ math.h library

Part​ ​B

Once you have the wind chill calculation working, create another function printWindChill​. This function should call windChillCalculator and print all the wind chill values for a fixed temperature and variable wind speeds. You will need to write a loop in this function to iterate over the different wind speeds. The function should receive T (air temperature), low_wind_speed, high_wind_speed, and wind_speed_step as input parameters. For Example: Let the input parameters be T = 30.0, low_wind_speed = 5.0, high_wind_speed = 8.0, and wind_speed_step = 1.0, your function should print out the wind chill for a temperature of 30 °F and wind speeds starting from 5 mph and ending at 8 mph, incrementing by 1 mph. (5 mph, 6 mph, 7 mph, and 8 mph) Use the following cout statement to output the values from within​ ​the​ ​function​: cout << "The wind chill is " << wind_chill << " degrees F for an airtemperature of " << T << " degrees F" << " and a wind speed of " << V << " mph." << endl;

Part A:

Screenshot of the code:

/Include the required header file. #include iostream» #include<math.h> using namespace std; //Define the function. float windChillCalculator (float T, float V) //Claculate the wind chill. float wind_chill-35.740.6215*T 35.75* (float) (pow (V,e.16)) e.4275*T (float) (pow(V,0.16)); //Return the wind child return wind chill; //Define the main function. int main() //Declare the variables. float V, T, wind_chill; //Prompt the user for input. cout<<"Enter the air temperature:" cout<<endl<<"Enter the wind speed:"; //Call the windChillCalculator function //to retrieve the wind chill value. wind_chill -windchillcalculator (T, v) //Display the results cout<<"The wind chill is " << wind_chill << " degrees F" << " and a wind speed of ..

Output:

Enter the air temperature:3 Enter the wind speed: 5.e The wind chill is 24.7268 degrees F and a wind speed of 5 mph.
