Hi i have to write a program to develop an interactive program that calculates the number of squares of siding and shingles for a rectangular house of any size. In addition to the amount of siding and shingles your program should calculate a material cost for siding and shingles.In addition to the amount of siding and shingles your program should calculate a material cost for siding and shingles. Your requirements for the program are:

1. Data is to be entered interactively.
2. The processed output to be displayed on the screen and written to a file.
3. The output will be properly formatted and labeled.
4. The interactive entry will allow for multiple houses to be entered before exiting the program.
5. For each house, there will be a line for the cost of siding and a line for the cost of shingles.
6. The squares of siding will have three costs, aluminum, vinyl and either wood or composite.


I have the code written but am unsure what to do next

#include <iostream.h>
#include <stdlib.h>
#include <fstream.h>
#include <cmath.h>
const float aluminum = 75.00
const float vinyl = 57.00

const float composite = 45.00;
const float standard = 50.00;
const float designer = 75.00;
const float total_siding;
const float total_shingle;
const float length;
const float width;
int siding_type;
int shingle_type;
float surface_area;
float pitch;
int choices;
ofstream roof_order;

void shingles();
void siding();
void sa();


int main()
{

roof_order.open("E:\\roof.txt");

cout << "enter the length of house in feet;" << " "<< '\n'

a = width /2
b = height of pitch
c = sqrt(pow(a,2) + pow(b,2));
roof_side = (c* length) * 2;
roof_front = ((width * pitch) /2) * 2;

//REMEBER TO FIND ALL VARIABLES IN THIS SECTION

height=(stories*2);
surface_area=2*((length*width)+(length*height)+(width*height)) + roof_side + roof_front;
do

}
if (siding_type<5)
{
total_siding = surface_area * siding_type

switch(wood_type);
