Im needing help with the following c++ code:

The program you are making needs to calculate the Volume and Surface area of regular blocks and save them as a record in a database. It currently has a Rectangle class and a main menu. You need to create a Block class that is derived from the Rectangle class.

1. Create the Block class that will be derived from the Rectangle class.

1. Create a constructor that receives the height, length and width and passes length and width along to the Rectangle class

2. Create a getSurfArea method and a getVolume method.

2. In the makeBlock function, ask the user for a height. Instantiate the Block class and use the getSurfArea and getVolume functions to find the total SurfArea and total Volume.

3. Write the line to save the block info (saveBlock() function in Rectangle.h file)

4. Write the code that will search through the file to find a block in the getBlock() function.

Rectangle Class:

//This file defines the Rectangle and Block classes as well as handling DB

functions

//getBlock and saveBlock

#include

#include

#include

using namespace std;

//Rectangle Class Declaration

class Rectangle

{

private:

long width;

long length;

public:

//constructor sets width and length

Rectangle(long w, long l)

{ width = w; length = l; calcArea(); }

//accessor functions for width and length

long getWidth()

{ return width; }

long getLength()

{ return length; }

//returns the rectangle's area

long calcArea()

{

long temp = length * width;

return temp;

}

};

class Block : public Rectangle

{

//<--------------------------------------------------Block code here

};

void saveBlock(string ID, long width, long length, long height)

{

ofstream fileOut;

//open file

fileOut.open("Blocks.txt", ios::app);

//<-------------------------code to place comma delimited block in

text file

fileOut.close();

}//end saveBlock

void getBlock(string blockID)

{

ifstream fileIn;

string record;

fileIn.open("Blocks.txt");

//if file doesn't open

if (fileIn.fail())

{

cout << "Problem Opening File.";

}

else

{

while(!fileIn.eof())

{

//<-----------------------------place code to search through

file for block

}//end while

cout << "Block not on record";

return;

}//end else

}//end getBlock

Main Menu:

/*

Description: This program will calculate the surface area and volume of a

regular

block which. It uses a rectangle class for the base of the block and then

derives

the block class from the rectangle class.

*/

number in meters: ";

//Rectangle base width

}while(width < 0);
