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 daily_salary;
    float working_days;
    float monthly_salary;
    //input 1
    cout<<"total day of that month=";
    cin>>day_of_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;
    float num5;
    float total;
    float average;
    //input 1
    cout<<"enter num1";
    cin>>num1;
    //input 2
    cout<<"enter num2";
    cin>>num2;
    //input 3
    cout<<"enter num3";
    cin>>num3;
    //input 4
    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>
    main()
    {
    //declare variable
    float height;
    float width;
    float radius;
    float base;
    float area_of_rectangle;
    float area_of_circle;
    float area_of_triangle;
    //input 1
    cout<<"enter height";
    cin>>height;
    //input 2
    cout<<"enter width";
    cin>>width;
    //input 3
    cout<<"enter radius";
    cin>>radius;
    //input 4
    cout<<"enter base";
    cin>>base
    //formula 1
    area_of_rectangle=height*width;
    //output 1
    cout<<"the area of rectangle is="<<area_of_rectangle;
    //formula 2
    area_of_circle=3.14*radius*radius;
    //output 2
    cout<<"the area of circle is="<<area_of_circle;
    //formula 3
    area_of_triangle=0.5*height*base;
    //output 3
    cout<<"the area of triangle is="<<area_of_triangle;
    return 0;
    }
