A store is having a sale. The manager wants a program that allows the sales clerk to enter the original price of an item and the discount rate. The program should calculate and display the sale price.Find the inputs and outputs, write the pseudocode, and desk check the pseudocode.

Pseudocode :

Create a Structure or Class

1. Initialize variables for ‘Original Price(price1)’, ‘Discount Rate(discount)’, ‘Sale Price(price2)’.

2. Declare functions or modules for Inputting Data, Calculation, Outputting Data.

Define Function for Inputting Data

1. Input Original Price(price1)

2. Input Discount Rate(discount)

Define Function for Calculation

1. Sale Price(price2)=price1-((price1*discount)/100)

Define Function for Outputting Data

1. Output Sale Price(price2)

Define Main Function

1. Input the Number of Items(size)

2. Declare Array of Structure or Object

3. FROM I=0 to I=size

Call Function for Inputting Data via Array of Objects

Call Function for Calculation

Call Function for Outputting Data via Array of Objects

4. Exit Loop

Program :

#include<iostream>

using namespace std;

class store

{

public:

float price1; //Original Price

float price2; //Sale Price

float discount; //Discount Rate

void getdata(); //Input

void cal(); //Calculation

void putdata(); //Output

};

void store :: getdata() //Enter Original Price & Discount Rate

{

cout<<"\nOriginal Price : ";

cin>>price1;

cout<<"\nDiscount Rate(%) : ";

cin>>discount;

}

void store :: cal() //Calculate the Sale Price

{

price2=price1-((price1*discount)/100);

}

void store :: putdata() //Output the Sale Price

{

cout<<"\nSale Price : "<<price2;

}

int main()

{

int size;

cout<<"\nEnter the Number of Items : "; //Number of Items

cin>>size;

store ob[size]; //Taking Array of Objects

cout<<"\n\n"<<"##"<<"Inputs & Outputs"<<"##"<<"\n\n";

for(int i=0;i<size;i++) //Input & Output Section

{

cout<<"\n\nItem "<<i+1<<" : \n";

ob[i].getdata(); //Calling getdata()

ob[i].cal(); //Calling Cal()

ob[i].putdata(); //Calling putdata();

}

cout<<"\n";

return 0;

}

Output 1 :

Enter the Number of Items : 3

##Inputs & Outputs##

Item 1 :

Original Price : 40

Discount Rate(%) : 2

Sale Price : 39.2

Item 2 :

Original Price : 60

Discount Rate(%) : 4

Sale Price : 57.6

Item 3 :

Original Price : 120

Discount Rate(%) : 4.5

Sale Price : 114.6

Output 2 :

Enter the Number of Items : 5

##Inputs & Outputs##

Item 1 :

Original Price : 87

Discount Rate(%) : 6

Sale Price : 81.78

Item 2 :

Original Price : 152

Discount Rate(%) : 7

Sale Price : 141.36

Item 3 :

Original Price : 888

Discount Rate(%) : 25

Sale Price : 666

Item 4 :

Original Price : 763

Discount Rate(%) : 52.6

Sale Price : 361.662
