    const Pi=3.14;

b) Declare a variable named perimeter with double data type
    double perimeter;

c) Give instruction that allowed user to input data
    cout<<"Enter data=";
    cin>>data;

d) Input number of computer using variable
    cout<<"Enter number=";
    cin>>nimber;

QUESTION 2
Change the if...else statement below to switch...case statement
#include<iostream.h>
main()
{
int selection,quantity;
float price;
cout<<"1.pen=rm0.50";
cout<<"2.pencil=rm0.30;
cout<<"3.ruler=rm0.20";
cout<<"4.Erasor=rm0.10";
cin>>selection;
cin>>quantity;
if(selection==1)
{price=quantity*0.50;}
else if(selection==2)
{price=quantity*0.30;}
else if(selection==3)
{price=quantity*0.20;}
else if(selection==4)
{price=quantity*0.10;}
else
{cout<<"Invalid selection";}
cout<<"the price is :"<<price;
return 0;
}

#include<iostream.h>

CHAPTER 5

TOPIC : IF ELSE ... SWICTH CASE......

EXAMPLE :

AGE   =    GENERATION
1-6      =  kids
7-12    =  child
13-21  =  teenagers 
22-30  =  adult
> 31    = old

if ..... else 

#include <iostream.h>
main ( )
{
declare variable
int age ;
// input
cout << " enter your AGE : " ;
cin >> age ;
//if else statement
if (age > = 1 II age <=6)
{cout << " you are kids ! " ;
else if ( age >=7 II age < = 12 )
{cout << '" you are child ! " ;
else if ( age >=13 II age <=21 )
{cout << " you are teenagers ! " ;
else if ( age <=22 II age <=30 )
{cout << " you are adult ! " ;
else if ( age > 30 )
{cout << " you are old ! " ;
else
{cout << "invalid selection" , ;
return 0 ;
}

swicth...case

#include < iostream.h>
main ( )
//declre variable
int age ;
//input
cout << " enter your age : " ;
cin >> age;
// swicth ... case statement
{ case ('age'>=1 II 'age' <= 6) : cout << " you are kids ! " ; break ;
case ( 'age'>=7 II 'age' <=12) : cout <<  " you are child ! " ; break ;
case ('age'>= 13 II 'age' <= 21) : cout << " you are teengers ! " ; break ;
case ( 'age' >= 22 II 'age' <=30) : cout << "you are adult ! " ; break ;
case ( 'age >30 ) : cout << " you are old ! " ; break ;
default : cout << " invalid selection " ;
}
return 0 ;

Chapter 4

1) Arithmetic operators :

    + + (Unary Plus)

    - - (Unary minus)

    + (Addition)

    - (Substraction)

    * (multiplication)

    / (Floating-point division / Integer division)

    % (Modulus)

Dlm C++, ade increament nan decrement operator..

    + + (Pre-increment) e.g + +m

    + + (Post-increment) e.g m+ +

    - - (Pre-decrement) e.g - -n

    - - (Post-decrement) e.g n- -

Tips utk sng hfl : klw simbol dy tuh kt dpn variable (Pre-), kne tambah or tolak nan 1.. tp klw simbol kt blkng (Post-) xyah tmbah pape.. ekot jek mcm soklan dy.. aq bg cth k..

SOALAN :        a = 2 , b = 3

                      m = 2 , n = 3

                       p = 2 , q = 3

                       x = 2 , y = 3            

(+ + a) + (- - b) * 4 > (+ + m) * (- - n) + 4

JAWAPAN :

               

2) Relational operators :

    < (Less than)

    > (Greater than)

    = = (Equal to)

    < = (Less than or equal to)

    > = (Greater than or equal to)

    ! = (Not equal to)

3) Logical operators : (0/False , 1/True)

    & & (AND) ----> ade je 0 mesti 0/false

    | | (OR) ----> ade je 1 mesti 1/true

    ! (NOT) ---->

    !(& &) (NOT AND) ---->

    !(| |) (NOT OR) ---->  | |

total=bm+bi+math+sains

average=total/4

OK niy step na wt jawapan :

1) Go to my computer

     

2) Choose Local Disk (C:)

3) Click folder TC > folder BIN

    

4) Click TC application

5) If your windows can't support this system for full screen, just ignore MS-DOS Subsystem table

    (terime jela screen yg comel loteh kecik na mampos tuhh)

6) After open the Turbot C++ , click file > new > type your group coding

7) Answer for exercise 2

8) Don't forget to save the coding

9) To compile, go to compile menu and click compile

10) Press any key

11) If you make any mistake, syntax error will appear

12) To run, go to run menu and click run
