The document explains flowcharts as diagrammatic representations of algorithms, highlighting their utility in programming and communication. It describes various flowchart symbols and provides examples of how to create flowcharts for calculating sums, determining maximum values, and checking even/odd or positive/negative numbers. Additionally, it includes flowcharts for calculating sums of numbers with conditional and looping statements.

INTRODUCTION
 Flowchart is a diagrammatic representation of an algorithm. Flowchart
is very helpful in writing program and explaining program to others.
 Different symbols are used for different states in flowchart, For
example: Input/output and decision making has different symbols.
 The table below describes all the symbols that are used in making
flowchart.
