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

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);
}
}
}
