Overview
In this tutorial, we will learn about different variable naming notations. Some of the notations are as follows:
- Camel case notation
- Pascal case notation
- Snake case notation
- Hungarian notation
camelCase
Camel case is a popular convention for naming variables. In this convention, the variable starts with a lowercase letter and any subsequent word begins with an uppercase letter.
For example, weeklyPay
PascalCase
Pascal case is a notation in which the first letter of the variable name is in uppercase. This notation is also called as upper camel case.
For example, SalariedEmployee
snake_case
Snake case notation in which the white spaces between the words are replaced with an underscore (_)
character. For example, hourly_wage
stringHungarian
Hungarian notation in which the variable’s data type is also part of the identifier name. For example, stringFirstName.
