b) Declare a variable named Parameter with double data type (declare variable)
c) Give instruction that allowed user to input data (input)
d) Input number of computer using variable (input assign to variable value)

2. Solve the question below. Show the working.

a) 5 * 2 % 3 + 25 / 5
b) a = 5, b = 6
!((a < 3) && (a == 3) || (b > 9))

3. Identify syntax errors in the following program.

include<iostream.h>
main()
{
float allowance = 300.00, salary;

cout<<"Input Salary = ";
cin>>salary;

TSalary = salary + Allowance;

cout<<"Salary is= "<< salary;
}

4. Write a program that will calculate the monthly salary for an employee that where Saturday and Sunday are considered as non-working days.

5. Write a program that calculates the average of 5 numbers that can be input by user.

6. Write a program that will calculate the area of rectangular, triangle and circle.


ANSWER.


1. a) Initializing variable Pi with the value 3.14 (constant).


   //declare
   float Pi=3.14


   b)Declare a variable named Parameter with double data type (declare variable)


   //declare Parameter
   double Parameter=5.776198


    c)Give instruction that allowed user to input data (input)


    //input
     cout<<"Enter data=" ;
     cin>>data;


   d)Input number of computer using variable (input assign to variable value)


      //declare nc=number of computer

      int nc;

    //Input

    cout<<”Enter number of computer=” ;

    cin>>nc;

2. a) 5 * 2 % 3 + 25 / 5

    = [10%3]+25/5

    = 1+5

    = 6

   b)  a = 5, b = 6

       ! ((a < 3) && (a == 3) || (b > 9))

    = ! [(0) && (0) || (0)]

    =1

• Dalam kelas hari ini miss sporting bagi brekfearst dulu and kelas star pukul 10 a.m.
• miss arahkan all sudn downlod note chapter1,2,3,4,6 in forum.
• Bermula la pegenalan subjek 4 :OPERATORS AND EXPRESSION.
• Bab ini mengenai, ARTIHMETIC OPERATORS,RELATIONAL,LOGICAL.
• Ini asas sahaja... :)
• Kemudian mengenai  INCIMENT yang terbahagi kepada 2 iaitu: PRE-INCIMENT & POST-INCIMENT.
• Later,DECREMENT terbahagi kepada dua: PRE-DECREMENT & POST-DECREMENT.
• And baut exercise bab 4 yg miss bagi di dalam kelas by group.
• Selepas habis bab4,terus kepada bab6 yang mencabar bagi aku..hehehe :)
• Bab ini baru sampai mengenai IF...ELSE & SWITCH....CASE
• Enjoy betul dalam kelas ini cz 4hour..hehehe :)
• Group partner yang tidak hadir pada hari ini adalah. Nurfadatul Akmar.
• Last,buat weekly reflection 4 by Group in forum..
• EXERCISE YANG LAST WEEK GROUP I  dapat FULL MARK..:):):):)
• HAPPY SANGAT,, :)

/ -->devision.
% -->modulus.


2.RELATIONAL OPERATORS.
> : greater than.
< : less than.
>= :greater than and equal.
=< :less than and equal.
== :equal.


3.LOGICAL OPERATOR.
&& :and.
! :not.
|| :or.


4.INCIMENT AND DECREAMENT.
