SECTION A - LOOPING


1. (Conversion from kilograms to pounds) Write a program that displays the following table (note that 1 kilogram is 2.2 pounds):

Kilograms Pounds

1         2.2

3         6.6

...

197       433.4

199       437.8

2        3.218

...

9        14.481

10       16.09


   

3. (Finding the highest score) Write a program that prompts the user to enter the number of students and each student's score, and finally displays the highest score.


 
4. (Finding the highest score) Write a program that input 15 students name and score and finally displays the student with the highest score.


 
5. (Summing a series) Write a program to sum the following series:

10+20+30+40+50……100

  

6. (Counting positive and negative numbers) Write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, Your program ends with the input 0.
For example, if you entered 1, 2, -7 and 0  the output should be

Positive numbers=2

Negative numbers =1
   

7.(Counting positive and negative numbers) Write a program that reads 20 number of integers, determines how many positive and negative values have been read


   

8.(Counting odd and even of positive  numbers) Write a program that reads an unspecified number of integers, determines how many odd and even values have been read. Your program ends with the input is negative (any negative number). Display the average as a floating-point number.

For example, if you entered 1, 2, 0 and -1  the output should be

Odd numbers=1

Even numbers =2

   

9.(Finding numbers divisible by 5 and 6) Write a program that displays all the numbers from 100 to 1000, ten per line, that are divisible by 5 and 6.




SECTION B – METHOD
Write method headers for the following methods:

1.    Computing a sales commission, given the sales amount and the commission rate.
2.    Computing the discount, given the price and discount amount (percentage).
3.    Printing the calendar for a month, given the month and year.
4.    Computing a square root.

BCS2233 OOP: LAB WEEK 3

Programming Exercises

2.1 (Converting Fahrenheit to Celsius) Write a program that reads a Fahrenheit degree in double from an input dialog box, then converts it to Celsius and displays the result in a message dialog box. The formula for the conversion is as follows:
celsius = (5/9) * (fahrenheit - 32)

Hint


  In Java, 5 / 9 is 0, so you need to write 5.0 / 9 in the program to obtain the correct result.



2.2 (Computing the volume of a cylinder) Write a program that reads in the radius and length of a cylinder and computes its volume using the following formulas:

area = radius * radius * p
volume = area * length


2.3 (Converting feet into meters) Write a program that reads a number in feet, converts it to meters, and displays the result. One foot is 0.305 meters.

2.4 (Converting pounds into kilograms) Write a program that converts pounds into kilograms. The program prompts the user to enter a number in pounds, converts it to kilograms, and displays the result. One pound is 0.454 kilograms.

2.5* (Calculating tips) Write a program that reads the subtotal and the gratuity rate, and computes the gratuity and total. For example, if the user enters 10 for subtotal and 15% for gratuity rate, the program displays $1.5 as gratuity and $11.5 as total.

2.6** (Summing the digits in an integer) Write a program that reads an integer between 0 and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14.
Hint


  Use the % operator to extract digits, and use the / operator to remove the extracted digit. For instance, 932 % 10 = 2 and 932 / 10 = 93

PART A




PART B


1.2 The issue of resource utilization shows up in different forms in different
types of operating systems. List what resources must be managed
carefully in the following settings:
a. Mainframe or minicomputer systems
b. Workstations connected to servers
c. Handheld computers

1.3 Under what circumstances would a user be better off using a timesharing
system rather than a PC or single-user workstation?

1.5 Describe the differences between symmetric and asymmetric multiprocessing.
What are three advantages and one disadvantage of multiprocessor
systems?

1.6 How do clustered systems differ from multiprocessor systems? What is
required for two machines belonging to a cluster to cooperate to provide
a highly available service?

1.9 How are network computers different from traditional personal computers?
Describe some usage scenarios in which it is advantageous to
use network computers.

1.10 What is the purpose of interrupts? What are the differences between a
trap and an interrupt? Can traps be generated intentionally by a user
program? If so, for what purpose?

1.11 Direct memory access is used for high-speed I/O devices in order to
avoid increasing the CPU´s execution load.
a. How does the CPU interface with the device to coordinate the
transfer?
b. How does the CPU know when the memory operations are complete?
c. The CPU is allowed to execute other programs while the DMA
controller is transferring data. Does this process interfere with
the execution of the user programs? If so, describe what forms of
interference are caused.

1.13 Give two reasons why caches are useful.What problems do they solve?
What problems do they cause? If a cache can be made as large as the
device for which it is caching (for instance, a cache as large as a disk),
why not make it that large and eliminate the device?
