I'm having trouble debuging the follwing program, can you help find the errors, thanks in advance.


//This program calls a function that asks the user for length
// and width of a room (in feet)
//Another function asks for price per sqaure yard for carpeting
//A final function calculates and displays the cost of carpeting the
room
#include<iostream.h>
void main()
{
int length, width;
double price;
void enterDimensions(int &length, int &width);
void enterCarpetPrice(double &price);
void displayFinalCost(const int &length, const int &width, const double
&price);
enterDimensions(&length, &width);
enterCarpetPrice(&price);
displayFinalCost(length, width, price);
}
void enterDimensions(int &length, int &width)
{
cout<<"\nEnter length of room ";
cin>>length;
cout<<"\nEnter width ";
cin>>width;
return;
}
void enterCarpetPrice(double &cost)
{
cout<<"\nEnter cost of carpet per square yard ";
cin>>cost;
return;
}
void displayFinalCost(const int &len, const int &wid, const double
&price)
{
double cost;
Cost = length * width/9 * price;
cout<<"\nCost is $"<<&Cost;
return;
}

This is C++ and not Pascal.

But I could try to find errors anyway.

Maybe this would work better :

//This program calls a function that asks the user for length
// and width of a room (in feet)
//Another function asks for price per sqaure yard for carpeting
//A final function calculates and displays the cost of carpeting the
//room
#include<fstream.h>
#include<iostream.h>
void main()
{
int length, width;
double price;
void enterDimensions(int &length, int &width);
void enterCarpetPrice(double &price);
void displayFinalCost(const int &length, const int &width, const double
&price);
//enterDimensions(&length, &width);
//enterCarpetPrice(&price);
//displayFinalCost(length, width, price);
}
void enterDimensions(int &length, int &width)
{
cout<<"\nEnter length of room ";
cin>>length;
cout<<"\nEnter width ";
cin>>width;
return;
}
void enterCarpetPrice(double &cost)
{
cout<<"\nEnter cost of carpet per square yard ";
cin>>cost;
return;
}
void displayFinalCost(const int &len, const int &wid, const double
&price)
{
double cost;
cost = len * wid/9 * price;
cout<<"\nCost is $"<<&cost;
return;
}

First of all, you need to include fstream.h in your code

These lines should either be removed or
be comments, like I have done here:
//enterDimensions(&length, &width);
//enterCarpetPrice(&price);
//displayFinalCost(length, width, price);

C++ is case-sensitive,

A little error in my code :

This one is correct and should work :

//This program calls a function that asks the user for length
// and width of a room (in feet)
//Another function asks for price per sqaure yard for carpeting
//A final function calculates and displays the cost of carpeting the
//room
#include<fstream.h>
#include<iostream.h>
void main()
{
int length, width;
double price;
void enterDimensions(int &length, int &width);
void enterCarpetPrice(double &price);
void displayFinalCost(const int &length, const int &width, const double
&price);
enterDimensions(length, width);
enterCarpetPrice(price);
displayFinalCost(length, width, price);
}
void enterDimensions(int &length, int &width)
{
cout<<"\nEnter length of room ";
cin>>length;
cout<<"\nEnter width ";
cin>>width;
return;
}
void enterCarpetPrice(double &cost)
{
cout<<"\nEnter cost of carpet per square yard ";
cin>>cost;
return;
}
void displayFinalCost(const int &len, const int &wid, const double
&price)
{
double cost;
cost = len * wid/9 * price;
cout<<"\nCost is $"<<cost;
return;
}
