    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 <<...
