Question

Write a C++ Snowman object. You should create the following 3 separate files:

Snowman.h: the header file for the Snowman object and function prototypes;

Snowman.cpp: the implementation of the project functions; and

SnowmanDriver.cpp: a program to test your Snowman object.

The Snowman object will contain the following attributes:

height (double, in feet)

weight (double, in pounds)

temperature (double, in degrees Fahrenheit)

hasHat (bool)

scarfColor (string)

The Snowman object will contain the following data and member functions:

constructor with no arguments

assume

height = 5ft,

weight = 300lbs,

temperature = 29.80F,

hasHat = true,

scarfColor = “RED”

constructor with five arguments: height, weight, temperature, hasHat, scarfColor

separate mutator functions for setting the height, weight, temperature, hasHat, & scarfColor

separate accessor functions for getting the height, weight, temperature, hasHat, & scarfColor

function to calculate the volume of the Snowman.

Assume: PI = 3.14159

H = height

[edit]Here is the Snowman class declaration:

[edit]Driver

The SnowmanDriver.cpp program should:

declare an array of 100 Snowmen

Ask the user for the name of the data file

Open the data file

check to make sure the file opened successfully

if the file FAILED to open return to step 2

Skip the first 2 lines of the data file.

read the height, weight, temperature, hasHat and scarfColor for an unknown number of Snowmen, assume that there is one record per line.

you may assume there are fewer than 100 Snowmen

store each Snowman in the array of Snowmen

don’t forget to close the data file

sort the array of Snowmen by scarf color and temperature

Report the following:

Print a list of all Snowmen sorted by scarf color and temperature

Total number of Snowmen with hats

Total number of Snowmen with a RED scarf

Average volume of all Snowman

All amounts should be rounded to two decimal points.

Snowman.h:

#include <iostream>
using namespace std;
class Snowman
{
double height;
double weight;
double temperature;
bool hasHat;

public:
