Golang Programs

The Go programming language (often referred to as Golang) is an open-source, expressive, concise, clean, and efficient programming language to make programmers more productive. It was developed by Robert Griesemer, Rob Pike, and Ken Thompson, and launched in 2009 by Google as an open-source project.

Golang programs / examples: This section contains solved Golang programs/examples on the various topics such as basic programs, conditions & control statement-based programs, looping programs, array & string programs, structure programs, function & package-based programs, etc. with examinations and outputs.
