สรุปครั้งที่ 1 โครงสร้างข้อมูลและขั้นตอนวิธี

โครงสร้างข้อมูล ( Data Structures )

      ข้อมูล ( Data )  หมายถึง สิ่งที่เกิดขึ้น ข้อเท็จจริงต่างๆ อาจเป็นตัวเลขหรือไม่เป็นตัวเลขก็ได้

     โครงสร้าง ( Structure ) หมายถึง ความสัมพันธ์ของสมาชิกในกลุ่ม

ตัวอย่างโครงสร้างข้อมูล แบ่งเป็น 2 ประเภท คือ

  1. โครงสร้างข้อมูลทางกายภาพ ( Physical Data Structure )
  2. โครงสร้างข้อมูลทางตรรกะ ( Logical Data Structure )

       กายภาพ = เห็นได้ , จับต้องได้
       ตรรกะ     = การคิด , ความคิด

























การเลือกใช้โครงสร้างข้อมูล 1. ต้องสร้างความสัมพันธ์สมบูรณ์ที่สุด
                                          2. ต้องง่ายต่อการดำเนินงานในระบบงาน

การแทนที่ข้อมูลในหน่อยความจำหลัก
             
            การเขียนโปรแกรม จะแทนที่ข้อมูลในหน่อยความจำหลักมีอยู่ 2 วิธี คือ

                1. การแทนที่ข้อมูลแบบ สแตติก ( Static Memory Representation )
                2. การแทนที่ข้อมูลแบบ ไดนามิก ( Dynamic Memory Representation )

ขั้นตอนวิธี ( Algorithm ) เป็นการแก้ไขปัญหาอย่างมีระบบ

           1. ต้องมีความถูกต้อง
           2. ต้องใช้เ้วลาในการปฏิบัติงานน้อยที่สุด
           3. มีความกระชับ สั้น มีเฉพาะขั้นตอนที่จำเป็นเท่านั้น
           4. ใช้หน่วยความจำน้อยที่สุด
           5. มีความยืดหยุ่้นในการใช้งาน
           6. ง่ายต่อการเข้าใจ

คำศัพท์ ( Word )

           1. width                  =       ความกว้าง
           2. length                  =       ความยาว ความลึก
           3. calculate Area     =       การคำนวณพื้นที่
           4. scanf                   =       การรับค่าผ่านคีย์บอร์ด
           5. printf                   =       แสดงค่าให้ดูเฉยๆ
           6. case sensitive      =       การใช้ตัวอักษรเล็กหรือใหญ่มีผล
           7. lower case          =       อักษรตัวพิมพ์เล็ก
           8. upper case          =       อักษรตัวพิมพ์ใหญ่      
           9. integer  ( int )       =      จำนวนเต็ม
         10. float                    =       จำนวนจริง

ตัวอย่าง การหาพื้นที่ รูปสี่เหลี่ยมผืนผ้า
       
           1. width
           2. length
           3. Rectangle area = width*length
           4. Display Rectangle Area
























#include "stdio.h"
  int width, length ;
  void main ( )
    printf("Width=") ;
    scanf("%d", width) ;
    printf("Length=") ;
    scanf("%d", length) ;
    rectangle_area = width*length ;
    printf("Rectangle Area = %d", rectangle_area) ;
 return 0

Vision

LG Electronics continues to pursue its 21st century vision of becoming a worldwide leader in digital—ensuring customer satisfaction through innovative products and superior service while aiming to rank among the world’s top three electronics, information, and telecommunications firms by 2010.
On our way, we hold tight to a philosophy of “Great Company, Great People,” underscoring our belief that only great people can create a great company.

Fast innovation calls for securing a competitive edge over the competition by setting—and meeting—the highest of goals in all realms of innovation, by at least 30%. This applies to new-product development and unveiling, innovation in design and technology—as well as product sales, market share, and corporate value.
Fast growth is the result of implementing strategies designed to swiftly expand market size and earnings, with and eye toward monetary growth.

Corporate Culture

Though a company can boast stellar management strategies and an outstanding and talented pool of employees, it is still necessary to adopt a corporate culture that can fully unleash the power of these capabilities.

NUTRILITE™ Protein Powder
