Out: FRI. 1th Dec. 2023 Due: FRI. 22nd Dec. 2023
Main objective of the assignment:
Understand C programming and practice to draw a flow chAug. to describe
the problem and coding in C.
You are given a struct product, Table-1 and Table-2 as listed below. You are
required to finish the assignment with given information.
- Write a report;
- Use a flow chAug. or another method, demonstrate the data flow;
- Explain how the structure/functions to be used;
- Program in C language;
- Output screenshot for each question;
1. You are required to finish struct product class[] = {} using Table-1.
struct product
{
int prono;
char fullname[20]
float price;
struct salelist;
};
Table-1. Product’ Record (Given as a file “product.txt”)
prono fullname price
101 mango 3.5
102 orange 2.4
103 banana 2.8
104 watermelon 3.7
105 pineapple 4.1
106 blueberry 5.0
107 cherry 5.5
108 cucumber 1.9
109 cabbage 2.0
110 broccoli 3.1
111 celery 1.9
112 pea 4.5
113 product name product price
*You are requested to modify the last record with any kind of product in the
supermarket, keep prono and price.
2. Sort the records based on price. You are required to write an
appropriate callback function, and output withoutsale list information
on screen.
3. Sale list can be accessed from Table-2. First, you need to sort product’s
records based on month. Then, write an appropriate callback function,
and output with sale list information on screen.
Table-2. Sale list Information (Given as a file “salelist.txt”)
pro no month sales volume discount
101 Sep. 41 10% off
101 Oct. 48 none
102 Nov. 50 10% off
103 Aug. 43 10% off

111 Oct. 96 none
112 Sep. 36 none
112 Nov. 73 10% off
112 Oct. 21 none
4. Calculate the total sale volume and average sale volume of each
product respectively, and output the them on screen.
5. Output all sales data of September with product information, write the
result to a new txt file and name the file with your Brunel id.
6. Calculate the total sale of each product, and output the top three on
the screen. To achieve this, you need to know that price of each
product varies according to discount of each month. For example: the
price of mango in September has a discount of 10% off. In other words,
the price of mango in September is 3.15. The total sale of mango in
September equals the total sale volume of mango in September
multiple the price of mango in September. Finally, we can get the total
sale of mango by adding up the sales of mango in September,
October,November and December.
7. Write a flow chAug. for each function.
Remarks:
* Solutions to all questions above need to be included one *.c file. In addition,
you are required to define a function for each question. e.g.:
main(), Q1_functionname(), Q2_functionname(), Q3_functionname(),
Q4_functionname() and Q5_functionname(). Qx_functionname() should be
given by yourself.
* The output for each question should be done in main() function.
* Do not include any Chinese characters in your assignment.
* You are required to write annotation before each function, and
annotation / description for important statements. e.g.:
/∗
@function function_name
@desc describe what is this function used for.
∗/
* The assignment should be submitted in a .doc/.docx or pdf file, all the
source code should be included, and output screenshot should be included.
