How to using function to rewrite this code?

Function Requirements: instructions a void function with no parameters print out instructions message as per output example (see below) intputData a void function with three parameters prompts user for the values of total pressure, static pressure and temperature and then puts these values into variables that were declared in main. processResults a void function with five parameters that calculates velocity and mach number from total pressure, static pressure and temperature. printReport a void function with five parameters that prints to the monitor an output report that meets the requirements shown below. Calculation of Mach number: Mach number is the velocity divided by the speed of sound.

Mach Number= velocity/speed of sound

Calculation of speed of sound:

The speed of sound is proportional to the absolute temperature. The formula below will give an estimate of the speed of sound in ft/sec using temperature in degrees Fahrenheit. Speed of Sound vs (Temperature in degrees Fahrenheit )

V_s=1086*sqrt((T+460)/460) ft/sec

Input Data Run the program with these two sets of input data:

Input Data Set	Total Pressure (psi)	Static Pressure (psi)	Temperature (deg F)
#1	30	14.7	90
#2	23	14.7	90

Output Requirements Your output should look like this: This program computes the velocity and Mach number based on two pressure values and a temperature. Follow the prompts.

Re-use code:

#include "stdafx.h"

#include

#include

using namespace std;

.

const double k = 1.4; // k is ratio of Specific heats for air

const double airDENSITY = 0.002378; // airDENSITY is at sea level standard conditions

. // units are in slugs per cubic foot

int main()

{

double totalPressure, staticPressure, airSpeed;

char answer;

.

cout << endl << "Do you want to enter pressure in psi? (Y or N) ";

cin >> answer; if (answer == 'y' || answer == 'Y')

{ cout << endl << "Type in the Total Pressure in psi >>>>> ";

cin >> totalPressure;

cout << endl;

cout << "Type in the Static Pressure in psi >>>>> ";

cin >> staticPressure;

totalPressure = totalPressure * 144.;

staticPressure = staticPressure * 144.; // These statements convert psi to pounds psf

}

else

{ cout << endl << "Do you want to enter pressure in psf? (Y or N) ";

cin >> answer;

if (answer == 'y' || answer == 'Y')

{ cout << " Type in the Total Pressure in psf >>>>> ";

cin >> totalPressure;

cout << " Type in the Static Pressure in psf >>>>> ";

}

else

{ cout << " Then I can't help you. Good bye. " << endl << endl;

exit(1);

}

}

airSpeed =

sqrt

( ( (2 * k)/(k-1))* (staticPressure / airDENSITY) *

(pow ( ( ( (totalPressure-staticPressure)/staticPressure) + 1) , (k-1)/k

) - 1

)

);

/* this calcuation gives airSpeed in units of ft/s as long as the pressures are in psf and the air density is in slugs per cubic foot and the air density is in slugs per cubic foot */

cout.setf(ios::fixed);

cout.setf(ios::showpoint);

cout.precision(1); // These statements merely format the output
