In the Go programming language, struct types and interfaces provide powerful ways to build readable and maintainable code. By using Go's structural composition and defining clear interfaces, we can create codebases that are easy to understand and modify. Let's explore these concepts in action.

Encapsulation in Go is achieved through package-level visibility and methods attached to structs. In Go, package-level visibility is achieved by starting the variable and method names with a lowercase letter, making them unexported and accessible only within the same package. Instead of classes, Go uses structs to group related fields and methods, making code more organized.

Consider student information scattered within a program:

Encapsulation is achieved by grouping these fields in a struct and creating methods to operate on them:
