Can someone please point out to me what I'm doing wrong . Below is my source code for a program I wrote to calculate the cost of carpet & installation given the length,width, discount and cost per sq. foot. Everything works fine except that it doesn't compute and less the discount amount. Someone please help.

Code:#include <iostream> #include <fstream> #include <cstdlib> #include <iomanip> using namespace std; const float labor = 0.35; const float tax = 0.085; void getData (int &length, int&width, int &discount, float &cost); void calculate (int length, int width, int discount, float cost, float &totalLabor, float &totalCarpet, float &installation, float &subtotal, float &total, float &taxamount, float &discountamount); void printResult(int length, int width,int discount,float cost,float totalLabor,float totalCarpet,float installation,float discountamount,float subtotal,float taxamount,float total); int main () { int length,width,discount; float cost,totalLabor,totalCarpet,installation,subtotal,total,discountamount,taxamount; getData(length,width,discount,cost); calculate(length,width,discount,cost,totalLabor,totalCarpet,installation,subtotal,total,taxamount,discountamount); printResult(length,width,discount,cost,totalLabor,totalCarpet,installation,discountamount,subtotal,taxamount,total); system ("PAUSE"); return EXIT_SUCCESS; } void getData(int &length, int &width, int &discount, float &cost) { cout << "Length of the room (feet)? " << endl; cin >> length; cout << "Width of the room (feet)? " << endl; cin >> width; cout << "Customer discount (percent)? " << endl; cin >> discount; cout << "Cost per square feet (xxx.xx)? " << endl; cin >> cost; } float calcInstall (int length, int width, float cost, float &totalLabor, float &totalCarpet) { totalLabor=length*width*labor; totalCarpet=length*width*cost; return totalLabor+totalCarpet; } float calcSubtotal (float installation,int discount,float &discountamount) { discountamount = installation*(discount/100); return installation-discountamount; } float calcTotal (float subtotal,float &taxamount,float &total) { taxamount=subtotal*tax; total=subtotal+taxamount; return total; } void calculate (int length, int width, int discount, float cost, float &totalLabor, float &totalCarpet, float &installation, float &subtotal, float &total, float &taxamount, float &discountamount) { installation=calcInstall(length,width,cost,totalLabor,totalCarpet); subtotal=calcSubtotal(installation,discount,discountamount); total=calcTotal(subtotal,taxamount,total); } void printMeasurement (int length,int width) { cout<<" THE BROOKLYN COLLEGE CARPET STORE" << endl; cout <<" ABDOOL RAHEEM, Owner" <<endl << endl << endl; cout <<" MEASUREMENT" << endl << endl;; cout << right << setw(35) << "Length" << setw(10) << length << left << setw(34) <<" feet" << endl; cout << right << setw(35) << "Width" << setw(10) <<width << left << setw(34) << " feet" << endl; cout << right << setw(35) << "Area" << setw(10) << length * width << left << setw(34) <<" square feet" << endl << endl << endl; } void printCharges(float cost,float totalCarpet,float totalLabor,float installation,int discount,float discountamount,float subtotal,float taxamount,float total) { cout <<" CHARGES"<<endl<<endl; cout << left << setw(20) << "DESCRIPTION" << right << setw(20) << "COST/SQ FT" << setw(20) << "CHARGE/ROOM" << endl; cout << left << setw(20) << "Carpet" << right << setw(20)<< fixed << setprecision(2) << cost << setw(20) << setprecision(2) << totalCarpet << endl; cout << left << setw(20)<< "Labor" << right << setw(20) << "0.35" << setw(20) << setprecision(2) << totalLabor << endl << endl; cout << left << setw(20) << "INSTALLED PRICE" << right << setw(20) << "" << setw(20) << setprecision(2) << installation << endl; cout << left << setw(20) << "Discount" << right << setw(20) << "" << setw(20) << setprecision(2) << discountamount << endl; cout << right << setw(60) << "----------" << endl; cout << left << setw(20) << "Sub Total" << right << setw(20) << "" << setw(20) << setprecision(2) << subtotal << endl; cout << left << setw(20) << "Tax" << right << setw(20) << "" << setw(20) << setprecision(2) << taxamount << endl; cout << left << setw(20) << "Total" << right << setw(20) << "" << setw(20) << setprecision(2) << total << endl; } void printResult(int length, int width,int discount,float cost,float totalLabor,float totalCarpet,float installation,float discountamount,float subtotal,float taxamount,float total) { printMeasurement (length,width); printCharges (cost,totalCarpet,totalLabor,installation,discount,discountamount,subtotal,taxamount,total); }
