DCT 2112 Programming Practical. Flowchart Exercise 17/7/13

An electric supply company charges the following rates for its customers:-

No. of unit consumed                              Charges/unit (RM)
1-200                                                           2.50
201 - 500                                                     3.50                                                  
over 501                                                       5.00

If the consumer pays his bill within 15 days from the bill date, 10% discount is given
. If he makes the payment after 15 days from the bill date, 5% surcharge is levied. Draw a flowchart to calculated the net amount of the bill for each consumer and print it.

the above flowchart not considered the calculation of discount and levied

DCT 2112 Programming Practical. Flowchart Exercise

Write an algorithm  for a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values, not counting zeros. Your program ends with the input 0. Display the average as a floating-point number. (For example, if you entered 1, 2, and 0, the average should be 1.5.)

Solution for DCT 2112 Programming Practical - LAB 10/7/13

Question 1

Question 3

 

Question 4

Write a program that read length and width of a rectangle and output it perimeter and area

DCT1083 Programming Fundamentals : LAB 1

•  Programming is a process of problem solving

•  Problem solving techniques:-
• Analyze the problem & Outline the problem requirenment
• Design steps (algorithm) to solve the problem
• Write a program 

 Exercise 1

Exercise 2
Write a program to find the area of a rectangle. The area of the rectangle is given by the following formula:
area = length x width

 














Exercise 3
Write program that calculates mileage reimbursement for a salesperson at a rate of RM 0.65 per kilometer. 

Your program should interact with the user in this manner :
Enter beginning odometer reading : 13505.5
Enter ending odometer reading :13810.6
You traveled 305.4 km 
Your reimbursement is RM 198.51

DCT 2112 Programming Practical

DCT 2112 Programming Practical ialah subjek yang akan mengasah kemahiran pelajar dalam pengaturcaraan. Berdasarkan suatu masalah - pelajar di kehendaki membina algorithma dan seterusnya menulis aturcara java. 


Dalam subjek ini - pelajar akan di minta membuat persembahan (presentation) terhadap algorithma dan aturcara yang telah di bina (secara berkumpulan). 

Pelajar di minta memberi perhatian yang lebih pada subjek  DCT 1093 Object Oriented Programming (oleh Puan Izzah Inani) kerana bahasa java akan di ajar di sana.

Bahan-bahan pengajaran adalah seperti berikut:-

1.Course Plan

2. Nota Kuliah (slide power point)

• Pseudocode
• Flowchart

Sila guna bahan rujukan bagi subjek DCT 1093 Object Oriented Programming atau buku berikut :-
