Question

C++

The manager of Keystone Tile wants an application that displays the area of a rectangular floor, given its measurements in feet.

It should also display the total cost of tiling the floor, given the price per square foot of tile.

1-Create a new project named Intermediate13 Project, and save it in the Cpp8\Chap04 folder.

Enter your C++ instructions into a source file named Intermediate13.cpp.

Also enter appropriate comments and any additional instructions required by the compiler.

Test the program using the same data used to desk-check the program.

Answer 1

/*
C++ program that prompts user to enter the lenght and width of the rectangle floor
and then prompt for price of sqt. Then calculate the total cost of the floor on the console output.
*/

//Intermediate13.cpp
#include<iostream>
#include<iomanip>
using namespace std;
//start of main function
int main()
{

   float length;
   float width;
   float area;
   float pricePerSFT;
   float totalCost=0;

   cout<<"Keystone Tile"<<endl;
   //read length of the floor
   cout<<"Enter length of The Floor :";
   cin>>length;
   //read width of the floor
   cout<<"Enter width of The Floor :";
   cin>>width;
   cout<<"Enter price per square feet :$";
   cin>>pricePerSFT;

   //area of the rectangle area
   area=length*width;

   //calculate the total cost of the floor
   totalCost=area*pricePerSFT;
   //print the total cost
   cout<<"Total cost of the rectangle floor : $"<<totalCost<<endl;

   system("pause");
   return 0;
}

Sample Output:

Sample run1:

Keystone Tile
Enter length of The Floor :5
Enter width of The Floor :10
Enter price per square feet :$1.5
Total cost of the rectangle floor : $75

Sample run2:

Keystone Tile
Enter length of The Floor :10
Enter width of The Floor :15
Enter price per square feet :$1.0
Total cost of the rectangle floor : $150
