What is an algorithm? Write any three characteristics of an algorithm.
Show SolutionHide Solution↓
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.
2
Define the term flowchart. Write any two advantages of a flowchart.
Show SolutionHide Solution↓
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.

Show SolutionHide Solution↓
It is used for accepting inputs or giving output of the program.
4
When do we use the Process box?
Show SolutionHide Solution↓
It is used for writing the processing instructions and doing calculations.
5
What is the use of Decision box?
Show SolutionHide Solution↓
It is used for checking or applying any condition in the program.
