Overview

In this tutorial, we will learn about Flowgorithm Identifiers and the naming conventions. An identifier uniquely identifies a variable in the flowchart.

A Flowgorithm identifier is a unique name given to the variable or function in the flowchart.
The flowchart programmer may use multiple variables in the flowchart.

We need to tell Flowgorithm before using a variable or user-defined function. We can use the Declare
flowchart symbol.

Naming Conventions

Flowgorithm follows some naming conventions we must adhere to while naming the variables.

• Identifiers must start with a letter followed by a series of letters or numbers. The first letter should be from a-z or A-Z.

For example, a valid identifier name is: length

• A valid identifier should not contain whitespace.

For example, Student Name is an invalid identifier because it contains a white space. The red color on the symbol indicates an error.

Many languages allow underscore( _ )  and other special characters within identifiers. However, Flowgorithm doesn’t allow special characters within identifiers names. For example, the following variable names are invalid in Flowgorithm. $HourlyWage , hourly_wage

• Identifiers cannot be reserved words or predefined keywords.

For example, the following identifier sin is invalid. sin is a pre-defined function name in Flowgorithm. It cannot be used as an identifier name.

The following identifier True is also invalid. True is a pre-defined keyword in the flowchart that represents the boolean state.

• Identifiers are not case-sensitive.

For example, the following identifiers name, NAME are the same in the Flowgorithm flowchart.
