Problem: Calculate the usable area in square feet of house. Assume that the house has a maximum of four rooms, and that each room is rectangular.
We are trying to calculate the square feet of a 4 bedroom house
To do this, I will need to know each room’s length and breadth, then calculate each room’s area before I will then find the total.
Map:
When * = times
Sum = total
Room# =Room number
Length# = length or a particular room
Breadth# = breadth or a particular room

Formula:
Area of Room1=length1*breadth1
Area of Room2=length2*breadth2
Area of Room3=length3*breadth3
Area of Room4=length4*breadth4
The total Number of Square Foot’s = Area of room1+ Area of room2+ Area of room3+ Area of room4

Program Design
Pseudo code:
Start
Declare the variables v ,A as integer length[4], breadth[4],area[4] as double array sum as double
Display “Enter the Rooms length and Breadth”
For v = 1 to 4 do
Accept length[v], breadth[v]
Next v
Display “Finding Area and total number of square foots”
Set sum =0
For A= 1 to 4
Area [A] = length [A]* breadth [A]
Sum = sum + Area [A]
Next A
Display “Total number of square foots”, sum
Stop

Program Comments and Test Data
C++ code:
#include<iostream>
#include<string>
Using namespace std; int main()
{
int v,A; double length[4], breadth[4] ,area[4], sum;
}
cout<<"\nEnter the length and breadth of each room"; for (v=0;v<4;v++)
{
cout<<"\nRoom "<<v+1<<" Length :"; cin >>length[i]; cout<<"\nRoom "<<v+1<<" Breadth :"; cin >>breadth[v];
}
sum=0; for (A=0;A<4;A++)
{
area[A]=length[A]* breadth[A]; sum=sum+area[A]; } cout<<"\nTotal number of square foots :"<<sum<<endl;

Return 0;
}
