In this page you will learn about What is Flowchart and its different symbol used in computer programming. After reading this page you will able to define flowchart and its different symbol with example.

    flowchart in C

    A flowchart is a symbolic or diagrammatic representation of an algorithms of a programs. It represents the process which is done in programs through the help of different symbols. It uses simple geometric shapes to represent processes and arrows to show relationship between geometric shapes. It is used in analyzing, designing, or managing a programs. It is a step by step approach to solving a program.

    Different types symbol used in flowchart are given below:

    • Process box
    • Input/Output box
    • Decision box
    • Connectors
    • Terminal
    • Flow-lines

    Explaining each symbol with the help of its pictures:
