MUTIARA INDAH COMPANY DISCOUNT SYSTEM

1 Problem Analysis:

1.1 Input

Based on the information given by the company, the discount system should applyaccordingly to the Table 1.0 below when the sale officer input/enter the unit of purchased

item and price. So the input of the system is unit item and price.

Table 1.0

Number BoughtUnit Price (RM)

0 – 10.00 10.01 – 100.00 100.01 – 1 – 9 0% 2% 5%10 – 99 5% 7% 9%

100 – 499 9% 15% 21%500 – 999 14% 23% 32%1000 – 21% 32% 43%

Input Declaration:

Unit item int unit;

Price float price;

Input screen:

Enter unit:

Enter price: RM

1.2 Process

As of the given information, the Mutiara Indah Company stated that their company needs

a system that are able to calculate and prints the total full cost, the discount given, and

the total after discount.

Process Declaration:

Discount float discount;

Total full cost float tprice;

Discount given float discount_given;

Total after discount float pay;



Process Formula:

Total full cost = Price × Unit item tprice = price * unit;

Discount given = Total full cost × Discount discount_given = tprice * discount;

Total after discount = Total full cost – Discount given pay = tprice – discount_given;

1.3 Output

Mutiara Indah Company needs a system that can prints the total full cost, the discount

given, and the total after discount.

Output Declaration:

Use/fetch the previous declaration.

Total full cost TOTAL COST float tprice;

Discount given TOTAL DISCOUNT float discount_given;

Total after discount PAYMENT float pay;

Output Screen:

TOTAL COST: |RM

− TOTAL DISCOUNT: |RM

PAYMENT: |RM
