Question 1

Question 1What is an algorithm? Write any three characteristics of an algorithm.

Accepted Answer

The step-by-step procedure to solve any logical and mathematical problem is called an Algorithm. Three characteristics of an algorithm are:Input — An algorithm accepts an input.Generality — An algorithm works in a set of inputs.Definiteness — Each instruction should be written in a simple and precise manner so that everyone can understand it.

Question 2

Question 2Define the term flowchart. Write any two advantages of a flowchart.

Accepted Answer

A flowchart is a pictorial representation of the steps or an algorithm used to solve a particular problem. Two advantages of a flowchart are:Communication — The pictorial representation of the flowchart provides better communication. It is easier for the programmer to explain the logic of a program.Effective Analysis — It is a very useful technique, as flowchart is a pictorial representation that helps the programmer to analyze the problem in detail.
