QUESTION 1:

Variables

A variable is the storage location in memory that is stored by its value. A variable is identified or denoted by a variable name. The variable name is a sequence of one or more letters, digits or underscore.
For example: character _

Rules for defining variable name:

Variable's name MUST be unique.
Cannot be more than 31 characters.
MUST begin with letters.
NO space in between.
Can't begin with numbers, symbols, or special characters.

DATA TYPES

CHARACTER
· Consist of all LETTERS, NUMBERS, and SPECIAL SYMBOLS.
· Surrounded by SINGLE QUOTATION MARK (' ' ).
· Example: 'A', 'm', '#', '1', or ' '.

STRING
· Combination of more than one character.
· Surrounded by DOUBLE QUOTATION MARK (" " ).
· Example: (" WELCOME TO MY PAGE") OR ("8876").

LOGICAL VALUES/BOOLEAN
· Making Yes-or-No decisions ( TRUE-or-FALSE).
· Example: to check two integers using if… … else control structure.
Assume a=2 and b=5
If (a
Decision is TRUE
Else
Decision is FALSE

INTEGER
· Whole POSITIVE and NEGATIVE numbers including ZERO and NO DECIMAL place.
· Example: 0, +1, -10.
· Used to represent the counting of things.
· Example: Numbers of month in a year (1,2,3 …).

FLOATING POINTS (FLOAT)
· Contain all numbers with DECIMAL points.
· Stored in floating point
· Used for metric measurement, temperature and price.
· Example: 1.0cm, 234.55kg, RM20.30, 36.7C.

DOUBLE
· Floating point data types comes in three sizes, namely float, double and long double.
· The difference is in the length of value and amount of precision which they can take and it increases from float to long double.
· double: This data type is used to represent double precision floating point number.

LONG DOUBLE
· This data type is used to represent double precision floating point number.

CONSTANT
· fixed values which cannot change.
· example 123, 12.23, 'a' are constants.

ARRAY
· A set of locations in the computer memory that has the same name and contains the same data type.
· It is almost the same as variable, but variable has allocated only one location that can store one value at a time. Where else, array can allocate more than one location to store several values at a time.

LONG/SHORT INTEGER
· LONG INTEGER: This data type is used to represent long integer.
· SHORT INTEGER: This data type is used to represent short integer.
the next example is:

Ape pasal ek? Pelik...
apsal nk install turbo C++ nih x bley...
saket ati tol... kt laptop x bley, kt PC x bley... abeh tu camne nk wat..
aku nih banyak sangat kot dosenye......... dari ari tu ade je masalah kalo nk wat keje..
Huuu... kene muhasabah diri nih...
Tiap kali nk wat keje je tenet x leh gune la.. xde karen la.. x masok lagik masalah2 yg len2...
Dulu sebok keje.. ni da brenti keje pon still x bley wat jugak.. Nk masak la.. Basoh baju la.. Husband balik uma tau da siap masak.. uma da bersih... hmm... bukan merungut.. tp rasenye aku pon still x pandai nk susun timing kot.. tu la antare sebab musababnye aku rase la...
Kadang2 tension.. tp still ingat tuhan... hehe...
Dulu nk g class problem keje... x sempat.. x de bas.. jalan jem.. skang da x keje.. ujan pulak tiap2 petang.. huh.. petang nih aku ade class nih.. tp xtau dpt g ke x.. sbb ujan nih.. siap ade petir dan guruh... kesiankan aku..
Pade kawan2 yg bace post nih... atau pade sesape yang berkenaan la.. kalau aku ade wat salah kt korang.. ade wat dose yg aku prasan atau x prasan.. (kadang2 gurau2 terkasar then x prasan korg touching....) aku mintak maaf la ye.. mungkin sbb banyak dose kt korang, aku nih slalu dilande masalah... aku berdoa semoga segala urusan aku berjalan dengan lancar... amin........

Lagik.. Chapter Two pulak...... (*_*)

Kat Chap 2 nih kitorg blajo pasal C++.. Erm amendealah uh.. Progamming language ke? uuuu... tu la.. mase class asik nk skip je.. padahnye sape nk nangung.. naseb ade membe yg prihatin kasik notes... Luv U gurlz.. Cayang korang.. hehe.. kat bawah nih contoh C++ yg mis aja... kalo nk wat mendealah nih mestilah berdasarkan flowchart yg kite wat uh..

Nk wat coding nih kene ikot rules macam kt bawah nih:
1) Mule2 kene ikot formula macam yg die bagi, area utk circle area= 3.14*radius*radius
2) Carik brape variable name yg ade pastu declarekan
3) Pastu wat flowchart ikot soklan
cth:start>read radius>area=3.14*radius*radius>print output >end
4) Pastu wat la coding macam kt atas uh..

START..............( Tu We Ige..) GO!!!!

Firstly kite start nan Chapter One la ek... Hmm..
Kat Chap 1 nih kitorg blajo tang Algorithm, Pseudocode, nan Flowchart...

Algorithm = sequence of instructions to solve a problem.

Pseudocode= outline of a program, written in a form that can easily bo converted into programming statement.

Flowchart = graphic representation of the logic or steps in a program.

e.g: Find Area Of Rectangle

Algorithm
Get the width of rectangle
Get the height of rectangle
Calculate the area of rectangle by multiply width by height
Display the area of rectangle

Pseudocode
Read the width
Read the height
Set the area = width*height
Print output

Flowchart
