This document discusses algorithms and flowcharts. It defines an algorithm as a logical step-by-step method for solving a problem and a flowchart as a graphical representation of an algorithm using standard symbols. Several examples of flowcharts are provided, including ones to find the largest of two or three numbers, check if a number is prime, and generate a Fibonacci series. The document also lists some common flowchart symbols and provides exercises for students to create flowcharts to solve various problems.

SUMMARY

3. Algorithm and Flowchart
Definition of Algorithm
To write a logical step-by-step method to solve the problem is called the algorithm; in other words, an
algorithm is a procedure for solving problems. In order to solve a mathematical or computer problem, this
is the first step in the process. An algorithm includes calculations, reasoning, and data processing.
Algorithms can be presented by natural languages, pseudocode, and flowcharts, etc.
Definition of Flowchart
A flowchart is the graphical or pictorial representation of an algorithm with the help of different symbols,
shapes, and arrows to demonstrate a process or a program. With algorithms, we can easily understand a
program. The main purpose of using a flowchart is to analyze different methods. Several standard symbols
are applied in a flowchart:
Algorithm Flowchart
It is a procedure for solving problems. It is a graphic representation of a process.
The process is shown in step-by-step instruction.
The process is shown in block-by-block information
diagram.
It is complex and difficult to understand. It is intuitive and easy to understand.
It is convenient to debug errors. It is hard to debug errors.
The solution is showcased in natural language. The solution is showcased in pictorial format.
It is somewhat easier to solve complex problem. It is hard to solve complex problem.
It costs more time to create an algorithm. It costs less time to create a flowchart.
