Answer the following questions

Question 1

What is a flowchart? What are the features of a flowchart?

Answer

A flowchart is a pictorial representation of an algorithm. It uses boxes of different shapes to represent different types of instructions. These boxes are connected with arrow marks to indicate the flow of operations.

The features of a flowchart are:

It is an easy method of communication.

It is independent of a programming language.

It is the key to correct programming.

It helps to plan and design a new system.

It clearly indicates the task to be performed at each level.

Question 2

What is an algorithm? What are its characteristics?

Answer

An algorithm is defined as the sequence of instructions written in simple English that are required to get the desired results. It helps to develop the fundamental logic of a problem that leads to a solution.

Some characteristics of an algorithm are as follows:

Each step of an algorithm must be precisely defined.

An algorithm must contain blocks that will help to solve problems more efficiently and logically.

It should accept a set of inputs and produce a defined output.

It must be terminated after a finite number of steps.

It should be independent from a computer programming language.

It should develop a platform for writing programs.

Question 3

Define the following and draw their symbols:

Algorithm

Step 1: Start

Step 2: Accept the length of the two line segments as l1 and l2.

Step 3: If l1 and l2 are equal, then display 'Line Segments are equal'.

Step 4: If l1 and l2 are not equal, then display 'Line Segments are not equal'.

Step 5: Stop.

Algorithm

Step 1: Start

Step 2: Accept the age of the person.

Step 3: If age is greater than or equal to 18, then display 'You are eligible to vote'.

Step 4: If age is less than 18, then display 'You are not eligible to vote'.

Step 5: Stop.

a certain battery can supply 6 J of energy to every coulomb of charge moving through a circuit. if the circuit consists of two i

SOVA2 [1]

Whatever energy the electrons have when they come out of one terminal of the battery, they completely use it up on their way around the circuit, and they stagger back into the other terminal of the battery totally exhausted, with no energy left.

If each coulomb of electrons has 6 joules of energy when they leave the battery, then that's the energy they'll give up to the circuit before they return to the battery.

For each coulomb of charge that moves through that circuit, each flashlight bulb
will take 3 joules of energy away from that coulomb, and turn the energy into heat
and light.

==> 2 bulbs, 3 joules per coulomb that flows through each bulb, total 6 joules
per coulomb that flows around the circuit.

Note:
The question says that the bulbs are in series, but that wasn't necessary.
The energy consumed by the bulbs would be the same if they're in parallel.

A cool extra factoid:
The battery gives each coulomb of electrons that leaves it 6 joules of energy.
There's a special name for "1 joule per coulomb of charge". That's the "<em>volt</em>".
A battery that gives each coulomb of charge 6 joules of energy is a 6-volt battery.

Create an application named TurningDemo that creates instances of four classes: Page, Corner, Pancake, and Leaf. Create an inter

pickupchik [31]

Answer:

1) TurningDemo

public class TurningDemo

{ public static void main(String[] args)

{

Leaf obj1 = new Leaf();

Corner obj2= new Corner();

Page obj3= new Page();

Pancake obj4= new Pancake();

} }

2) ITurnable

public interface ITurnable

{

public void Turn();

}

3) Leaf class:

public class Leaf implements ITurnable

{

}

Page class:

public class Page implements ITurnable

{

}

Corner class:

public class Corner implements ITurnable

{

}

Pancake class:

public class Pancake implements ITurnable

{

}

Explanation:

The first is TurningDemo application which creates instance obj1, obj2, obj4 and obj4 of four classes Page, Corner, Pancake, and Leaf. new keyword is used to create new object or instance of each class.

The second is ITurnable interface. It contains a single method Turn() which is of type public.

Thirdly, classes named Page, Corner, Pancake, and Leaf implement ITurnable. implements keyword is used to implement a interface so this interface can be used by these classes.

These classes can also implement turn() of ITurnable interface as follows:

Leaf class:

public class Leaf implements ITurnable

{ public void turn()

{

}

Page class:

public class Page implements ITurnable

{

public void turn()

{

}

Corner class:

public class Corner implements ITurnable

{ public void turn()

{

}

Pancake class:

public class Pancake implements ITurnable

{ public void turn()

{

}
