If a variable is written as FirstName, what is the naming convention followed?

• A. Snake case
• B. Pascal case
• C. Kebab case
• D. Lower camel case

Answer: (B)

The variable named FirstName follows the Pascal case naming convention. In Pascal case, each word in the variable name begins with an uppercase letter and there are no spaces or separators between words. This convention is often used in programming languages for naming classes, types, or other identifiers to improve readability. In Pascal case, the first letter of each component is capitalized, as seen in "First" and "Name." This makes it clear that the variable consists of two separate words. This style is commonly adopted in languages like C#, Java, and others for class names and publicly exposed methods. Other naming conventions, such as snake case, use underscores to separate words and are typically written in all lowercase (e.g., first_name). Kebab case utilizes hyphens for separation (e.g., first-name) and is primarily used in URLs or certain configuration files, while lower camel case starts with a lowercase letter and capitalizes subsequent word starts (e.g., firstName).
