Question

One for getting input

One to compute and return the wind chill

One to compute and return the cloud base

One for the output

The output will be formatted exactly as shown below (use setw(x)) with the introduction as shown and notes as appropriate.

Use the cmath library for the power function (i.e. you need #include <cmath>)

The equation for approximating the wind chill factor in North America is:

wc = 35.74 + 0.6215 * Ta - 35.75 * V0.16 + 0.4275 * Ta * V0.16

Where:

Ta is the air temperature in Fahrenheit

V is the wind speed in mph (use the pow(windSpeed,0.16))

Note: it's acceptable to use the different magic numbers within your program

Explanation / Answer

#include <iostream>

#include <iomanip>

#include <cmath>

using namespace std;

void takeInput(float *temp, float *wp, float *dp){

printf(" Enter the temprature in degrees Fahrenheit: ");

scanf("%f",temp);

printf("%.1f ",*temp);

printf(" Enter the wind speed in mph: ");

scanf("%f",wp);

printf("%.1f ",*wp);

printf(" Enter the dew point in degrees Fahrenheit: ");

scanf("%f",dp);

printf("%.1f ",*dp);

}

float calculateWC(float &temp,float &wp){

return 35.74 + 0.6215*temp - 35.75*pow(wp,0.16) + 0.4275*temp*pow(wp,0.16);

}

float calculateCB(float &temp,float &dp){

return (temp-dp)*1000/4.4;

}

void showOutput(float temp,float wp,float dp,float wc,float cb){

std::cout << std::fixed;

std::cout << std::setprecision(1);

cout<<endl;

cout<<setw(15);

cout<<"Temprature";

cout<<setw(15);

cout<<"Wind Speed";

cout<<setw(15);

cout<<"Dew Point";

cout<<setw(15);

cout<<"Wind Chill";

cout<<setw(15);

cout<<"Cloud Base";

cout<<endl<<" ";

for(int i=0;i<75;i++){

cout<<"-";

}

cout<<endl;

cout<<setw(11);

cout<<temp<<" df";

cout<<setw(11);

cout<<wp<<" mph";

cout<<setw(11);

cout<<dp<<" df";

cout<<setw(11);

if(wc>=50||wp<=3)

cout<<"***";

else

cout<<wc<<" df";

cout<<setw(11);

cout<<cb<<" ft";

cout<<endl<<" ";

if(wc>=50||wp<=3){

cout<<" *** Temprature must be 50 degrees or less, and windspeed must be above 3 mph to calculate the wind chill";

}

}

int main() {

printf(" --------------------------------------------------------- | This program determines wind chill using temprature | | in Farhenheit and wind speed in mph. and computes | | the cloud base using the dew point in Fahrenheit | --------------------------------------------------------- ");

printf(" ");

float temp,wp,dp,wc,cb;

takeInput(&temp,&wp,&dp);

wc = calculateWC(temp,wp);

cb = calculateCB(temp,dp);

showOutput(temp,wp,dp,wc,cb);

return 0;

}
