Go Programming

Course Overview

Course Description:Learn the basics of Go programming, including syntax, data types, functions, and control structures. Ideal for those new to coding or transitioning from other languages.

Topics Covered:

• Basics of Go syntax and programming concepts
• Data types, variables, and basic operations
• Control flow: loops and conditionals
• Functions, methods, and error handling
• Introduction to Go's concurrency model with goroutines and channels

Syllabus

Module 1: Go Fundamentals

• Introduction to Go & installation (Go install, Go Playground)
• Go program structure (package main, func main())
• Variables, constants, data types
• Operators, expressions, type conversion
• Control structures: if, for, switch

LAB 1

• Install Go and run Hello World in terminal & Go Playground
• Write programs for factorial, Fibonacci, prime check
• Create a calculator using switch

Module 2: Functions, Arrays, Slices & Maps

• Functions (return values, multiple returns)
• Pointers in Go
• Arrays & Slices
• Maps (key-value storage)
• Structs & Methods

LAB 2

• Implement a To-Do List app using slices
• Build a dictionary app using maps
• Create a student struct with methods (add, display)

Module 3: Concurrency & Error Handling

• Go routines & concurrency model
• Channels (unbuffered, buffered)
• Select statement
• Error handling (error type, custom errors)
• Packages & modularity

LAB 3

• Write a multi-threaded counter using goroutines
• Implement message passing using channels
• Build a file reader with error handling

Module 4: Advanced Go & Projects

• Interfaces & Polymorphism
• File I/O (read/write JSON, CSV)
• Web development with Go (net/http package)
• Using external modules (Go modules, dependency management)
• Capstone Project (end-to-end)

LAB 4

• Parse a JSON file into Go structs
• Build a REST API using net/http
• Connect Go app with SQLite/PostgreSQL
• Capstone: Create a mini-project (Blog API, Chat App, Expense Tracker, or URL Shortener)

Learning Outcome

• Grasp core Go programming syntax and data handling.
• Develop applications using functions, slices, maps, and structs.
• Implement concurrency using goroutines and channels.
• Build APIs and real-world projects using Go modules and web frameworks.
