Question

Please help in c++, follow the instructions, please. try to use pass by reference and pass by value if you could

Description:

• Write a program that will input wind speed and temperature and output the wind-chill factor.
• W = 35.74 + 0.6215 ∗ T − 35.75 ∗ V 0.16 + 0.4275 ∗ T ∗ V 0.16
• Your program should use at least 2 functions in addition to main. One that uses pass by reference parameters and prompts the user for both temperature (T) and wind speed (V). Another function that calculates and returns the wind chill factor (W).

Sample Run #1 (bold, underlined text is what the user types):

Wind Speed and Temperature? 35 30

Wind Chill Factor = 13.8938

Answer 1

Thanks for the question.

Below is the code you will be needing Let me know if you have any doubts or if you need anything to change.

=====================================================

#include<iostream>
#include<cmath>

using namespace std;

// returns by value
double calculateWindChill(double speed, double temperature){
  
   return 35.74 + 0.6215*temperature -35.75*pow(speed,0.16)+0.4275*temperature*pow(speed,0.16);
}

// passed by reference
void get_inputs(double &speed, double &temperature){
   cout<<"Wind Speed and Temperature? ";
   cin>>speed;
   cin>>temperature;
}

int main(){
  
   double speed, temperature, wind_chill;
   get_inputs(speed,temperature);

   wind_chill = calculateWindChill(speed,temperature);
   cout<<"Wind Chill Factor = "<<wind_chill<<endl;
}
