Go Programs with Output

Welcome to our collection of 40+ Golang (Go) programs with output, organized into 6 topic-wise sections. Each program is explained in its own blog post, with the code, comments, and sample output to help you understand the logic and execution flow.

Go is a fast, simple, and statically typed programming language developed at Google. It is widely used for cloud services, microservices, command-line tools, and DevOps tooling. Whether you are a beginner starting your Go learning journey or an experienced coder sharpening your skills, practicing these programs will also help you crack coding interviews.

What this page covers:

• Fundamentals: basic programs and mathematical programs (Sections 1 and 2).
• Strings and arrays: string manipulation and array operations (Sections 3 and 4).
• Algorithms and data structures: linear and binary search, sorting algorithms, and stacks and queues (Sections 5 and 6).

How to use this page: Beginners should start with Section 1 and try to write each program on their own before reading the solution.
