Variable Naming Rules

In Go, variable names must follow specific rules to ensure clarity and avoid errors. A well-named variable makes code easier to understand and maintain.

1. Rules for Naming Variables

• Must start with a letter (such as a-z or A-Z; Go also accepts Unicode letters like é) or an underscore (_).
• Can contain letters, digits (0-9), and underscores (_).
• Cannot start with a digit.
• Cannot use Go's reserved keywords (e.g., func, var, package).
• Variable names are case-sensitive (name and Name are different).
