Tasks:

Question 1. Write 150 words answers to the conceptual understanding of procedural and object-oriented programming and compare them.

Question 2. Write program (code) for the following scenario:

ABC Mall is a retail company selling various items. They need to calculate the commission for their staff based on the rates below

Less than $1,000	2.5%
$1,000 - 4,999 5%
$5,000 - 9,999 7.5%
$10,000 - 14,999	10%
$15,000 or more	12.5%

The company also allow their staff to ask for advance payment. Write a program for the following:
- Ask the staff to enter monthly sales
- Ask the staff to enter the amount of advanced pay
- Use monthly sales to calculate the commission.
- Calculate the staff pay by subtracting the advanced pay from the total commission.
- If the amount is negative, inform the staff they cannot ask for that much advance pay.

Question 3. Write program (code) for the following scenario:

Write a program that prints checks username and password
- First asks the user to register a username and password.
- Save these in two String variables.
- Now ask the user to enter the username, check if it matches the original entered username (ignore case), otherwise ask to enter again
- Ask the user to enter password (make sure to check the case also), otherwise ask to enter again
- At the end just confirm to the user that they entered the correct username and password.

Question 4. Debugging
See the program below, which has syntax and/or logic errors. In each case, determine the problem and fix the errors.

Program:

public class Averager
{
public static void main(String() Args)
{
Scanner keyboard = new scanner(System.in);

System.out.println("Enter a list of nonnegative scores.); System.out.println("Mark the end with a negative number.") System.out.println("I will compute their average.");

double next, sum; int count = 0;

next =input.nextDouble( ); while(next >= 0)
{
sum = sum + next; count+;
next = keyboard.nextDouble( );
}

if (count == 0)
System.out.println("No scores entered."); else
{
double average = sum/count; system.out.println(count + " scores read."); System.out.println("The average is " + average);
}
}
}
