Step 2. The Insert dialog box appears.

Step 3. Select appropriate option.

(a) Shift cells right

(b) Shift cells down

(c) Entire row

(d) Entire column

4. How to insert a Worksheet?

Step 2. A new worksheet is added before the selected worksheet.

5. If you add a row to the excel sheet, the total number of rows remains

the same. Why?

Ans:- The new row appears to be added, however only shifting of the rows

occur in MS Excel.

6. Explain the Auto Fill feature in MS Excel.

Ans:- The Auto Fill feature allows you to quickly fill the cells with repetitive

or sequential data such as chronological dates, numbers or repeated

text. This feature is implemented by using the Fill Handle of the

selected cell.

7. What are the various option available in Insert dialog box?

Ans:- The Insert dialog box gives the following options:

(a) Shift cells right

(b) Shift cells down




(c) Entire row

(d) Entire column

8. How do you resize a cell in MS Excel?

Ans:- By resizing column width and row height we can resize a cell.

Match the following

1. Fill Handle – (b) generates the data series

2. Delete row – (c) Use Edit menu

3. Delete cells – (d) Shifts the cells up or left

4. Center align – (e) Horizontal alignment

5. Top align – (a) Vertical alignment

State whether the following sentences are True or False

1. You can not resize a column width. – False

2. The delete dialog box shows three options. – False

3. Left, Right and Center are the three types of vertical alignment. – False

4. The Auto Fill feature can be used with numbers only. – False

5. Editing of the cells can be done using Cut, Copy, Paste commands. - True




Chapter 9 – Learning Algorithms

Fill in the blanks 1. Algorithms form a fundamental part of computing.

2. The tools of the algorithm are – Flowchart and Pseudocode.

3. Flowcharts use shapes as symbols to represent an activity.

4. Pseudocode is an informal language that helps programmers to develop

algorithms.

5. Flowchart and pseudocode are tools of an Algorithm.

6. Pseudocode means False code.

7. Symbols are used to make flowchart.

8. Flowchart is a graphical representation of an algorithm.

9. Pseudocode does not follow any standard for writing the instructions.

Answer the following questions.

1. What do you mean by an algorithm?

Ans:- Algorithm is an effective method of solving a problem using sequence of

instructions. An algorithm is a step-by-step process of doing a task. It

produces an ordered sequence of steps that provides solution to a

problem.

2. What is flowchart? Define symbols used in a flowchart?

Ans:- Flowcharts are graphical representation of an algorithm.

Various symbols are used in a flowchart are given below:

Name Symbol Description

Terminator Box

It represents the

beginning or end of a

flowchart.

Input / Output Box

It represents the

input and output

operations in a

flowchart.

Process Box

It represents the

process or an




instruction to be

carried out

Decision Box

This symbols is used in

branching when a

decision is to be made.

Connector Box

It connects one part

of the flowchart to

another.

Flow Lines

It depicts the flow of

information from one

point to another.

3. Give advantages and disadvantages of using a flowchart.

Ans:- Advantages:

1. The symbols are easier to understand.

2. Graphical nature makes the process of explaining an algorithm

quite straightforward.

3. Problems can be analysed in a more effective way.

Disadvantages

1. Difficult to understand complex programs.

2. Standard rules to be followed for making a flowchart.

3. Diagrammatic representation takes lot of time.

4. If changes are required the flowchart may require re-drawing

completely.

4. What is pseudocode? Give an example.

Ans:- Pseudocode means “False code”. It helps programmers to develop

algorithms. It is written in simple English like statements to represent

the logic of the program. Non-programmer can easily understand the

general working of the program.

Ex. Begin

Input Length, Breadth

Calculate Area = Length * Breadth

Display Area

End




5. Give advantages and disadvantages of pseudocode.

Ans:- Advantages:

I. Pseudocode can be constructed quickly as compared to

flowchart.

II. Closer to programming code, so easier to understand.

Disadvantages

I. Difficult to understand and manipulate.

II. No Standard are used, so difficult to maintain consistency.

6. What is programming statements?

Ans:- The set of instructions written in an algorithm is known as programming

statements. There are basically of three types:

a. Sequential – The step by step procedure to write the instructions.

b. Conditional – When the flow of the control of a program is based

on a condition.

c. Iteration or loop – To repeat a set of statements more than once

based on the certain condition.

Match the following 1. Sequence – (c) Instructions written one after the other

2. – (d) Process

3. – (a) Flow of information

4. Iteration – (e) Instructions are repeated

5. Pseudocode – (b) False code

Define Terms 1. Algorithm – It is a step by step process of doing a task.

2. Flowchart – It is a graphical representation of an algorithm.

3. Loop – It is a process of repetition based on certain condition.

4. Pseudocode – It means false code.

Rearrange the pseudocode in proper order 1. Start

Display “Charge fine depending on the speed”

Calculate Speed

Display “Program Ends”

If speed > 60

Display “Pay the fine”




Otherwise

Display “Good practice”

End if

Input Distance, Time

End

Ans - Start

Display “Charge fine depending on the speed” Input Distance, Time Calculate Speed

If speed > 60

Display “Pay the fine”

Otherwise

Display “Good practice”

End if

Display “Program ends”

End

2. Start

Display “Looping Ends”

Do while I > = 1

Display I

Let I = I – 1

End Loop

Let I = 5

Display “Display numbers from 1 to 5 in reverse order”

End

Ans - Start

Display “Display numbers from 1 to 5 in reverse order” Let I = 5

Do while I >= 1

Display I

Let I = I – 1

End Loop

Display “Looping Ends”

End
