OPERATORS AND EXPRESSION

1) Arithmetic operators
++ (plus)
-- (minus)
+ (addition)
- (substraction)
* (multiplication)
/ (floating point division / int division)
% (modulus)

2) Increment and decrement in C++

++ (pre-increment) ++m
++ (post-increment) --n
-- (pre-decrement) --n
-- (post-decrement) n--

EXAMPLE 1:

1) a=2 , m=2 , p=2 , x=2 , b=3 , n=3 , q=3 , y=3



question :
(++a) + (--b) * 4> (++m) * ( -- n) + 4
=(2+1) + (3-1) * 4> (2) * (3) + 4
= 3+2* 4> 2*3+4
= 3+8 > 6+4
= 11 > 10
= true/1

3) Reltional operators:-

< less than
> greater than
== equal too
<= less than or equal too
>= greater than or equal too
!= not equal too

4) logical operators

( 0/FALSE = 1/TRUE ) && (AND) {tips if got 0 will be 0/false}




II (OR) { TIPS IF GOT 1 WILL BE 1/TRUE


! (NOT) 


(&&) NOT AND


EXAMPLE :

a=2 , m=2 , p=2 , x=2 , b=3 , n=3 , q=3 , y=3

++ a + --b * 4 > ++m * --n +4 && p++ + q -- * 4 < x++ * y-- + 4
(2+1)+(3-1)*4 > (2+1)*(3-1)+4 && 2+3*4 < 2*3+4
3 + 2 * 4 > 3 * 2 +4 && 2 + 12 < 6+4
11 > 10 && 14 < 10
1/true && 0/false
0/false

WEEKLY REFLECTION 2

class on 9 Feb 2011 

Exercise programming ( group discussion )

Question :-
Add and minus number 1 & number 2 with using the formula below

ADD = NUM1 + NUM2 
MINUS = NUM2 - NUM1

Flowchart : Start ---> read number 1 ----> read number 2 ----> add = num1 + num2 / minus = num2 - num1 --- > display output ----> end

( MISS SORRY NI DAH SAVE FLOWCHART DLM PIC FORMAT JPEG , TP STILL XTAU CMNE NK UPLOAD DLM NI   )

Programming :-

remark : banyak yang betul dari yang salah time ms check .. beberapa simbol ; tertinggal di belakang sentences, agk hura hara jugak nk buat programming ni ... tp exercise ni xde markah ... 

# include < iostream.h >
main ()
{
// variable declaration
int num1 , num2 , add ,minus ;
// input 1 
cout << " enter num1 : " ;
cin >> num1 ;
// input 2 
cout << " enter num2 : " ;
cin >> num2 ;
// formula
add = num1 + n2 ;
// output 
cot << " minus = <<
minus ;
return 0
}

EXERCISE 1

Question 1

A) [5*2] % 3 + 25/5

=[10 % 3] + 25/5

=1 + 5

= 6#

2. a=5 b=6

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

! [ (5 < 3) && (5 == 3) || (6> 9) ]

! [ ( 0 ) && ( 0 ) || ( 0 ) ]

! [ ( 0 ) ( 0 ) ]

! ( 0 )

= 1#

Question 2

#include <iostream.h>

main( )

{

float allowance = 300.00,salary;

//input

cout << ”input salary = “;

cin >> salary;

salary = salary + allowance;

//output

cout << “salary is = “<< salary;

return 0;

}

Question 3

#include <iostream.h>

main()

{

//declare variable

float no_working_day,salary_per_day,monthly_salary;

//input1

cout << ” enter no working day = “;

cin >> no_working_day;

//input2

cout << “ enter salary per day = “;

cin >> salary_per_day;

//formula

monthly_salary = no_working_day + salary_per_day;

//output

cout >> “monthly salary = “<<monthly_salary;

return 0;

}

Question 4

#include <iostream.h>

main()

{

//variable declaration

float num1,num2,num3,num4,num5,total,average;

//input1

cout<<"num1= ";

cin>>num1;

//input2

cout<<"num2= ";

cin>>num2;

//input3

cout<<"num3= ";

cin>>num3;

//input4

cout<<"num4= ";

cin>>num4;

//input5

cout<<"num5= ";

cin>>num5;

//formula

total = num1 + num2 + num3 + num4 + num5/5;

//output

cout<<"average= "<<total;

return 0;

}

Question 5

#include <iostream.h>

main()

{

//variable declaration

int length,width,radius;

float areaR,areaT,areaC;

//input

cout<<"Enter the length= ";

cin>>length;

cout<<"Enter the width= ";

cin>>width;

cout<<"Enter the radius= ";

cin>>radius;

//formula

areaR = length * width;

areaT = 0.5 * length * width;

areaC = 3.142 * radius * radius;

//output

cout<<"The area of rectangle: "<<areaR;

cout<<"The area of triangle: "<<areaT;

cout<<"The area of circle: "<<areaC;

chapter 1 :
algorithm (arahan pnjg) > pseodocode (arahan pendek) > flowchart > programming C++

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

example 1 :
Find the area of rectangle
Area = width * height[/color]
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
Read width > raed height > set the area = width * height > print output >end


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 :
start > read radius > area = 3.14 * radius * radius > print output > end


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



Flow chart
Start > read celcius > set the area = ( 9/5 ) *( celcius + 32 ) > print output >end
