EXERCISE C1 & C2

Add and minus two INTEGER numbers with using the formula below:


add= num1+num2
minus= num2-num1

ANSWER

# include <> #header
main ( )
{
// variable declaration
int num 1,num 2,add,minus ;
// input 1
Cout << " enter num 1 : " ;
Cin >> num 1 ;
// input 2
Cout << " enter num 2 : " ;
Cin >> num 2 ;
// formula
add = num 1 + num 2 ;
// output
Cout << add =" <<">
// formula
minus = num 2 - num 1 ;
// output
Cout << " minus = <<
minus ;
return 0 ;
}

#include //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”<

Return 0 ;

} // close curly bracket

//end bracket

CHAPTER TWO

#include //header

Main ( ) // start body

{ // Open curly bracket

} // close curly bracket

// comment hidden

// 1 line 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. 1. Look and aware of formula
2.Find how many variable name
3.Declare variable

Input:

Cout <<“----------------------” ;

Cin >>variable_name_that_had_declared;

Rules: carefull with spelling,alphabet small and big

Output:

Cout <<“----------------------”<<

variable_name_that_had_declared;

CHAPTER ONE example 3

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

CHAPTER ONE example 2

Example 2:

find the area of celcius

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

Algorithm

1.get the fahrenheit of celcius

2.calculate celcius equal to 5 devide by 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

CHAPTER ONE example 1

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

CHAPTER ONE

ALGORITHM – Is sequences of instruction to solve a problem

PSEUDOCODE – Is the textual approach to illustrate an algorithm while flowchart is a graphical approach to illustrate an algorithm
