C#Identifiers

C# Identifiers

All C#variables must beidentified withunique names.

These unique names are calledidentifiers.

Identifiers can be short names (like x and y) or more descriptive names (age, sum, totalVolume).

Note: It is recommended to use descriptive names in order to create understandable and maintainable code:

// Goodint minutesPerHour = 60;// OK, but not so easy to understand whatm actually isint m = 60;

The general rules for naming variables are:

• Names can contain letters, digits and the underscore character (_)
• Names must begin with a letter or underscore
• Names should start with a lowercase letter, and cannot contain whitespace
• Names are case-sensitive ("myVar" and "myvar" are different variables)
• Reserved words (like C# keywords, such asint ordouble) cannot be used as names
