Quản lý motobike - Quản lý xe cộ - Lập trình C
1. Data [1.0]
Declare 1 struct:
-struct motorbike_st: char name[20], char manufacturer[10], char madein[12], long int price
- In main() function, declare an array of 3 motorbikes named “motorbikeList”.
2. Write a menu-based program with the following menu: [1.5]
Input data of motorbike
Sort, display details information and statistic of all motorbikes
Find the motorbike of manufacturer
Save to text file motorbike.txt.
Exit.
3. Input data of motorbikes[ 4.0]
When user chooses 1 from main menu, do the followings:
This module must be coded in a function which does the followings:
Have a motorbike_st struct array arguments
Store value from user’s input into motorbikeList array in main() function.
4. Sort, display details information and statistic of all motorbikes.[ 6.0]
When user chooses 2 from main menu, sort the motorbikes with descending order of manufacturer and display details information of each motorbikes with format below. Display number of motorbikes by manufacturers:
No ||Name ||Manufacturer||Made In||Price||
001|| Sirius||Yamaha||Viet nam||28000000||
002||Air Blade||Honda||Viet nam||40000000||
003||Dyland||Honda||Thai Lan||150000000||
Yamaha has 1 motorbike
Honda has 2 motorbike
This module must be coded in a function which does the followings:
Have a motorbike_ststruct array argument
5. Find the motorbike of manufacturer [4.0]
When user chooses 3 from menu, do the followings:
Display “Enter manufacturer for search : ”
Find and display detail information of the motorbikes of this manufacturer with format in Question 4. In case you don't find any motorbike of this manufacturer display “There are no motorbike of this manufacturer”
This module must be coded in a function which does the followings:
Have a motorbike_ststruct array argument
6. Save to text file motorbike.txt[3.0]
When user chooses 4 from menu, the program save name and manufacturer of each motorbike into a text file “motorbike.txt”.
This module must be coded in a function which does the followings:
Have a motorbike_st struct pointer argument.
Create a file “motorbike.txt” in text mode
Store name, manufacturer of each motorbike into this file
Close the file.
7. Exit[ 0.5 ]
When user chooses 5 from main menu, the program end.
