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
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
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 notation in which the white spaces between the words are replaced with an underscore (_)
character. For example, hourly_wage
Hungarian notation in which the variable’s data type is also part of the identifier name. For example, stringFirstName.
