Flowchart In Programming

Flowchart is a diagrammatic representation of an algorithm. Flowchart are very helpful in writing program and explaining program to others.

Symbols Used In Flowchart

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
