Algorithm and Flowchart

 

1. What is a program?

A program is a set instruction written to carryout a particular task, so that computer

can perform some specified task.

2. What is algorithm?

Algorithm means the logic of a program. It is a step-by-step description of how

to arrive at a solution of a given problem.

3. What are the steps to solve the problem in a computer system?

Problem must be analyzed thoroughly, Solution method is broken down into a sequence

of small tasks, Based on this analysis, an algorithm must be prepared to solve the problem, The algorithm is expressed in a precise notation. This notation is known as “Computer Program”, The Computer program is fed to the computer, The instruction in the program executes one after another and outputs the expected result.

4. How can you measure the quality of algorithm?

The primary factors that are often used to judge the quality of an algorithm are

time requirement, memory requirement, and accuracy of solution.

5. What are the characteristics of an algorithm?

1. In algorithms each and every instruction should be precise, 2. In algorithms each and

every instruction should be unambiguous, 3. The instructions in an algorithm should not be

repeated infinitely, 4. Ensure that the algorithm will ultimately terminate, 5. The algorithm should

be written in sequence, 6. It looks like normal English, 7. The desired result should be obtained

only after the algorithm terminates.

6. How many types the Algorithm can be represented?

Normal English, Program, Flowchart, Pseudo code, Decision table

7. What is decision table?

A decision table is a table containing the selection of conditions to be tested and how

those conditions should be nested to arrive at the proper action.

8. What is Flowchart?

A Flowchart is a pictorial representation of an algorithm. It is often used by programmer

as a program planning tool for organizing a sequence of step necessary to solve a problem by a computer.

9. What is the need of Flowchart symbols?

Each symbol of different shapes denotes different shapes denote different types of

instructions. The program logic through flowcharts is made easier through the use of symbol that

has standardized planning.

10. What is pseudo code?

“Pseudo” means imitation of false and “code” refers to the instruction written in the

programming language. Pseudo code is programming analysis tool that is used for planning

program logic.

11. What is structured programming?

A structured programming is a more specific approach to solve a programming problem

by using only the three basic logic structures. They are sequence logic, selection logic and

Iteration logic.

14. What is sequence logic?

Sequence logic is used for performing instructions one after another in a sequence.

15. What is selection logic?

Selection logic is used for selecting the process path out of two or more alternative paths

in the program logic. It uses three control structures called if…then, if… then…else and

switch…case.

16. What is Iteration logic?

Iteration logic is used for producing loops in program logic when one or more

instructions may be executed several times depending on some condition. It uses two control

structures called do…while, and repeat…until.

17. What are the rules for writing pseudo code?

Write on statement per line, Capitalize initial keywords, Indent to show hierarchy, End

multi line structure, Keep statements language independent.

18. What are the features of word processors?

Fast, Permanent storage, Formatting, Editing, Graphics, OLE, Spell Check, Mail merge

19. How many types a documented can be viewed?

Normal view , Online layout, Outline view , Page layout view

20. What are the menus available in Ms-Word?

File, Edit, View, Insert, Format, Tools, Table, Window, Help

21. What is meant by Formatting?

Formatting is the process of changing the appearance of the text in the document.

22. Specify any five toolbars available in Ms-Word?

Standard, Formatting, Drawing, Tables & Boarders, WordArt etc.,

23. How many Line Spacing options available in Ms-Word?

Single, 1.5 Lines, Double, At least, Exactly, Multiple

24. What are the Text cases available in Ms-Word?

Sentence case, lower case, UPPER CASE, Title Case, tOGGLE CASE

25. What is Subscript and Superscript?

The Subscript format places the text slightly below a line of normal printed text.

Eg:-H2O The Superscript format places the text slightly above a line of normal printed text.

Eg:-A2+B2

27. Define Headers and Footers.

Header allows text, page number or section titles to appear on every page of document at

the top position. Footer allows text, page number or section titles to appear on every page of

document at the bottom position.

28. What is a Table?

A Table is grid of rows and columns.

29. What is a Clipart?

Clipart is the attractive pre-defined, pre-colored pictures available in Ms-Word office

suite.

30. Define a Template.

Template is a special kind of document that produces basic tools for shaping a final

document.

31. Enlist the advantage of algorithm.

The term algorithm is now applied to many kinds of problem solving that employ a

mechanical sequence of steps, as in setting up a computer program. The sequence may be

displayed in the form of a flowchart in order to make it easier to follow.

32. State the usage of Excel application software.

Microsoft Excel is a spreadsheet tool capable of performing calculations, analyzing data

and integrating information from different programs. Microsoft Excel is comprised of

organizational units called workbooks. A standard workbook contains worksheets and chart

sheets. Worksheets perform calculations, store and organize data, present graphics and controls

like a web page; they are extremely versatile. A worksheet in turn is comprised of millions of

cells. The job of a cell is to store a formula that performs a calculation or communicates with

some other application (i.e. program) such as a database.
