1.    Write correct C++ syntax & for each statement below:

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

    Const float Pi=3.142;

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

      Double parameter

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

   

    Cout<<”please insert your score”;

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

    //variable nc=number of computer

    Int nc;

    //input

    Cout<<”Insert number of computer:”;

    Cin>>nc;

1.    Solve the question below. Show the working.

a) 5 * 2 % 3 + 25 / 5

    [(5*2)%3] + [25/5]

    [(10)%3] + [5]

    [1] + [5]

    6

b) a = 5, b = 6
    !((a < 3) && (a == 3) || (b > 9))

    NOT[(5<3:0)&&(5==3:0) || (6>9:0)]

    NOT[(0&&0) || 0]

    NOT[0 || 0]

    NOT[0]

    1

2.    Identify syntax errors in the following program.

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

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

TSalary = salary + allowance;

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

return 0;
}

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

#include <iostream.h>

main()

{

      //declare

      float allowance=500.00,salary=40,tsalary,day;

      //input

      cout<<"please input total days work";

      cin>>day;

      //process

      tsalary = (salary*day)+allowance;

      //output

      cout<<"The total salary for this month is:RM "<<tsalary;

      return 0;

      }

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

#include<iostream.h>

main()

{

//declare variable

float a,b,c,d,e,average;

//input

cout<<”please insert 5 numbers here: \nExample: a,b,c,d,e”<<endl;

cin>>a, b, c, d, e;

//process

average = (a+b+c+d+e)/5;

//output

cout<<”The average is:”<<average;

return 0;

}

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

#include <iostream.h>

main()

{

      //declare

      float b,h,r,w,area,;

      float pi=3.14;

      int selection;

      //out

      cout<<"Please choose you choice"<<endl;

      cout<<"1.Rectangular";

      cout<<"\n2.Triangle";

      cout<<"\n3.Circle"<<endl;

      cin>>selection;

      switch (selection)

      {

             case 1: cout<<"Please input the height"<<endl;

                     cin>>h;

                     cout<<"Please input the width"<<endl;

                     cin>>w;

                     //process

                     area = w*h;

                     cout<<"The area is:"<<area;

                     break;

             case 2: cout<<"Please input the height"<<endl;

                     cin>>h;

                     cout<<"Please input the base"<<endl;

                     cin>>b;

                     //process

                     area = 0.5*b*h;

                     cout<<"The area is:"<<area;

                     break;

             case 3: cout<<"Please input the radius"<<endl;

                     cin>>r;

                     //process

                     area = pi*r*r;

                     cout<<"The area is:"<<area;

                     break;

             default :cout<<"Invalid Selection";

             return 0;

             }

}
