chapter 2!!!!!!!!!!!!!!!!

#include <IDStream.h> //header

Main ( ) // start body

{ // Open curly braket

} // close curly braket

// comment hidden

//  1 baris coding

/ * , * / sume coding @ lbh dr 1 coding

Declare variable

Data_type              variable_name

Data type

Int	Integer
Float	Float	Decimal
Double	Double	Decimal
Char	Character	a-z /A-Z
String	String	Sentences
Const	Constant	Tak berubah

Rules:

1.     ~ Tengok formula

2.    ~Cari ade bape variable name

3.    ~Declare variable

Input:

Cout <<“----------------------” ;

Cin >>variable_name_that_had_declared;

 Rules: carefull dgn ejaan,huruf (kck & bsr)

Output:

Cout <<“----------------------”<<

variable_name_that_had_declared;

sample question!!!!!!!!!!

flow chart :

#include <iostream.h>//header

Main(   ) //start body

{  // Open curly braket

//declare variable

Float area;

Float radius;

// input 1

Cout <<“enter radius”;

Cin>> radius;

//formula

area = 3.14 *radius*radius

//output

Cout <<“answer”<<area ;

Return 0 ;

}  // close curly braket

//end baraket

* ciap pown tok chptr 2 nie...

chptr 2 nie agk ssh..tp kalo kite ley fhm n focus bnda nie sng jewk....hhehehe

ape yg pnting : kne wt step by step...

kalo kite da slh wt tok algoritm o pseudocode mknye kite akn slh gk wt bnda nie...

alert kt ejaan ea...jgn ade yg slh...

Chapter 1!!!!!!!!!!!

ALGORITHM – Is sequences of instruction to solve a problem…(ayt yg pngjg2)

PSEUDOCODE – Is the textual approach to illustrate an algorithm while flowchart is a graphical approach to illustrate an algorithm (ayt yg pndk)

sample question!!!!!!!!!!!!!!!!!!

example 1 :

Find the area of rectangle

Area = width * height

Algorithm

1.Get the width of rectangle

2.Get the height of rectangle

3.Calculate the area of rectangle with multiply width by height

4.Display the area of rectangle

Pseudocode

1.Read width

2.Read Height

3.Set the area = width * height

4.Print output

Flow chart

example 2:

find the area of celcius

celcius = (5/9) * ( fahrenheit-32)

Algorithm

1.get the fahrenheit of celcius

2.calculate celcius equal to five devide by name multiply by fahrenheit minus 32

3.display the area of celcius

pseudocode:

1.read fahrenheit

2.set the celcius = (5/9) * ( fahrenheit - 32 )

3.print output

flow chart :

example 3:

find the area of fahrenheit

fahrenheit =( 9/5 *( celcius + 32 ) )

Algorithm

1.get the celcius of fahrenheit

2.calculate fahrenheit equal nine devide by five multiply celcius plus 32

3.display fahrenheit

pseudocode

1.read celcius

2.set the fohrenheit ( 9/5 *( celcius + 32 ) )

3.print output
