jom blaja pasal if...else statement & switch...case statement

ok bdasarkan table kt ats . kite bole wt program dlm 2 jenis bentuk . sama ade dlm bntuk if...else ataupon switch...case . ok now kite wt dlm bentuk if..else statement dlu k ..

IF...ELSE STATEMENT

#include<iostream.h>

main()

{

//declare variable

int age;

//input

cout<<"Enter your age=";

cin>>age;

//if...else statement

if(age>=1||age<=6)

{cout<<"you are kids !!";}

else if(age>=7||age<=12)

{cout<<"you are child !!";}

else if(age>=13||age<=21)

{cout<<"you are teenager !!";}

else if(age>=22||age<=30)

{cout<<"you are adult !!";}

else if(age>30)

{cout<<"you are old !!";}

else

{cout<<"Invalid selection";}

return 0;

}

SWITCH...CASE STATEMENT

#include<iostream.h>

main()

{

//declare variable

int age;

//input

cout<<"Enter your age=";

cin>>age;

//switch...case statement

switch(age)

{

case('age'>=1||'age'<=6):cout<<"you are kids !!";break;

case('age'>=7||'age'<=12):cout<<"you are kids !!";break;

case('age'>=13||'age'<=21):cout<<"you are kids !!";break;

case('age'>=22||'age'<=30):cout<<"you are kids !!";break;

case('age'>30):cout<<"you are kids !!";break;

default:cout<<"Invalid selection";

}

return 0;

}

hmm kadang soklan suh kite tuka if...else jd switch...case . kadang tuka switch...case g if...else . tp kadang soklan ta bg programming, tp kite kene develop sndry..





mid term da lepas .. alhamdulillah :D

hmm td tepat pkul 1p.m xm FOP . jantong aq mcm na gugo .tkot yg teramat sgt . sbb subject niy kan susa . tp alhamdulillah aq dpt jwb . cume yg variable name tuh aq btol btol lupe . terpakse tembak ;P hehe hm lw stakat na lulus bole la, tp lw na dpt highest mimpi jelaaa ): hmm btw, td mis ade tulis kt white board suh siap kn blog, sume ass n sume weekly reflection . tekejot aq bc . hmm due date ary niyy lak tuhh . adehh hope mis check blog aq nt tga tga mlm . lw skg, mmg ta lengkap ag la . jp g na wt k (:

jawapan ! (:

msok cls, nmpk je kak lia n kak syezza, aq tros join dorang.. discuss cmne na wt jwpn utk questions yg mis bg last week.. actually num 1 nan 2 aq da wt da.. tp ade salah siket.. tQ kak syezza sbb da tego part mne yg sala.. ok jom bwat jwpn.. hee

1) a) 5 * 2 % 3 + 25 / 5

        = (5 * 2) % 3 + (25 / 5)  settle bhgi nan darab dlu

        = (10 % 3) + 5  settle modulus dlu

        = 1 + 5

        = 6

   b) a = 5 , b = 6

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

       = !(( 5 < 3 ) & & ( 5 = = 3 ) | | ( 6 > 9 ))   msok kn nilai a nan b dlu

       = !((    0   ) & & (     0     ) | | (    0    ))   tntukan true / 1 or false / 0

       = !((    0   ) & & (     0     ) | | (    0    ))   settle kn & & dlu

       = !((    0    ) | | (    0    ))   br settle kn | |

       = !(0)   klu not / !, kne tebalek kn

       = 1 / True

2) Identify the syntex error in the following program

    include<iostream.h>  x letak simbol #

    mai()  ejaan sala, tetinggal hruf n

    {

     float allowance=300.00,salary;

    cout<<''Input Salary=";

    cin>salary;  sala simbol, ptot nye >>

    Tsalary=Sallary+Allowance;  formula sala, hruf T x perlu ade

    cout<<"salary is="<<salary;  lpas output, kne ltax return 0;

    } 

   JAWAPAN :
    #include<iostream.h>

    main() 

    {

     float allowance=300.00,salary;

    cout<<''Input Salary=";

    cin>>salary; 

    salary=Sallary+Allowance; 

    cout<<"salary is="<<salary;
    return 0;

    } 

3) FORMULA : working_days=day_of_month-non_working_days
                          monthly_salary=daily_salary*working_days
    #include<iostream.h>
    main()
    {
    //declare variable
    float day_of_month;
    float non_working_days;

    float working_days;
    float monthly_salary;
    //input 1
    cout<<"total day of that month=";

    //input 2
    cout<<"non working days is about =";
    cin>>non_working_days;
    //input 3
    cout<<"daily salary is=";
    cin>>daily_salary;
    //formula 1
    working_days=day_of_month-non_working_days;
    //output 1
    cout<<"total working days is ="<<working_days;
    //formula 2
    monthly_salary=daily_salary*working_days;
    //output 2
    cout<<"the monthly salary is ="<<monthly_salary;
    return 0;
    }

4) FORMULA : total = num 1 + num 2 + num 3 + num 4 + num 5
                       average = total / 5
    #include<iostream.h>
    main()
    {
    //declare variable
    float num1;
    float num2;
    float num3;
    float num4;

    cout<<"enter num4";
    cin>>num4;
    //input5
    cout<<"enter num5";
    cin>>num5;
    //formula 1
    total=num1+num2+num3+num4+num5;
    //output 1
    cout<<"total="<<total;
    //formula 2
    average=total/5;
    //output 2
    cout<<"average="<<average;
    return 0;
    }

5) FORMULA : area of rectangle = height * width
                        area of circle = 3.14 * radius * radius
                        area of triangle = 0.5 * height * base
    #include<iostream.h>

EXAMPLE 2

EXAMPLE 3

chapter four ..

ok guys.. setelah sekian lame aq ta update ini blogggg, huhh ase cm malash la plaak na update.. haha.. tp na tanak kne update jgak!! (: mulekan nan bismillah cm bese.. hee hmm ok last week punyer class, miss bg notes utk chap 3 & 4.. tp knp ekk?? knp chap 3 kite ta blaja?? ntahh laa aq pon ta paam.. yg aq tw kite tros start nan chap 4.. express! :D miss trang kn byk bnde actually.. tp ad yg ta msok otak aq.. sbb kdng aq berangan.. tp lg byk yg msok dpd yg ta msok tuhh.. insyallah

Di sbbkn dlm bab niy kte blaja psl pngiraan, so tht byk simbol kte kne egt.. tw takkk?? meh sini bia aq aja ap je simbol yg aq ckp tuhh..

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 mesty 0/false

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

    ! (NOT) ----> tebalek kn jer.. klw 1, jwpn 0.. klw 0, jwpn 1

    !(& &) (NOT AND) ----> jwpn tbalek nan & &

    !(| |) (NOT OR) ----> jwpn tbalek nan | |
