Flowgorithm Identifiers

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

An example of an invalid identifier name is: 1foo

The variable name starts with a digit. The first character should not be a digit. Flowgorithm will generate a syntax error for the invalid identifier names.

Flowgorithm Identifiers

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.

Invalid Identifier Whiespace Flowgorithm

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