average=total/4

ANSWER

#include<iostream.h>//header

main()//start body

{//open curly bracket

float bm;

float bi;

float math;

float sains;

float total;

float average;

//input 1

cout<<"bahasa melayu=";

cin>>bm;

//input 2

cout<<"bahasa inggeris=";

cin>>bi;

//input 3

cout<<"matematik=";

cin>>math;

//input 4

cout<<"sains=";

cin>>sains;

//formula

total=bm+bi+math+sains;

//output

cout<<"total="<<total;

//formula

average=total/4;

//output

example 1 

       Find Area Of Circle [formula : area=3.14*radius*radius]  

       ALGORITHM

*Get the radius of circle

*Calculate the area of circle with 3.14 multiply by radius by radius

*Display the area of circle

       PSEUDOCODE

*Read the radius

*Set the area = 3.14*radius*radius

*Print output

       FLOW CHART :

example 2

 

      Find Celcius [formula : celcius = (5/9)*(fahrenheit-32)]

        ALGORITHM

*Get the fahrenheit of celcius

*Calculate celcius equal to five divided by nine multiply by fahrenheit minus 32

*Display the celcius of fahrenheit

       PSEUDOCODE

*Read the fahrenheit

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

*Print output

       FLOW CHART :

 

examlpe 3

      Find Fahrenheit [formula : fahrenheit = (9/5)*(celcius+32)]
        ALGORITHM
*Get the celcius of fahrenheit
*Calculate fahrenheit equal to nine divided by five multiply by celcius plus 32
*Display the fahrenheit of celcius

       PSEUDOCODE
*Read the celcius
*Set the fahrenheit = (9/5)*(celcius+32)
*Print output

       FLOW CHART :

Chapter Two

 #include<iostream.h> //header

main( ) //start body

{ //open curly bracket

 //declare variable

float area;

float radius;

 //input 1

cout<<"Enter radius=";

cin>>radius;
 //fomula

area=3.14*radius*radius;
//output

cout<<"area="<<area;

return 0;
}//close curly bracket

 //end Body

step2 nak wat nye :
1) firstly ngok formula yg tlah dibagi ;

*example area utk circle is area=3.14*radius*radius

2) second,cari bpe banyak variable name yg ade dlm cnth yg diberi.

3) then, declare variable

4) after that, wt flow chart bdasarkan soklan yg dy bg
*cth : start > read radius > area=3.14*radius*radius > print output > end

5) haa dh settle semua tdi,bru leh start wt coding.. ade beberape pkare yg sgt penting dlm coding niy.. antarenye :
*in the 1st line mest msukkn #include<iostream.h>
*in the 2nd line maskkn main()
*3rd line jgn lupe wt { tok strating & pntup wat body
*all in flow chart kne tulis dlm body
*huruf depands pade soalan sama ade huruf kecik smua @ besar
*xbole ade space except 4 the certain part mcm comment, declare variable and input&output yg ade dlm ("") & return 0
*dlm coding,jgn lupe letak simbol semi colun;

Comment

• //*utk 1 baris coding
• /* , */ = utk ksuluruhan coding / >1 baris coding
• depands pde u all nk jarak2 @ rapat2

Declare variable ( Start )
*wjib hafal & kne tau k..

DATA TYPE	INTEGER
Integer	Integer (o-9)
Float	Float (decimals)
Double	Double (decimals)
Char	Character (a-z / A-Z)
String	String (Sentences)
Const	Constant (pi=3.142)

Input

           cout<<"________";
           cin>>variable_name_thae_had_declare ;

WAJIB TAU :

• jgn salah ejaan,huruf besa @ kecik 
• key in ikot soklan, jgn short form2
• * bahasa melayu= jgn wat bm plak. xbly suke2 wat short form k 
• dlm ( " " ) tplang pde u all nk space @ x 

Output

         cout<<"______"<<variable_name_that_had_declared ;
