In Go, a struct is a composite data type that groups together variables under a single name. These variables are called fields. Each field has a name and a type. Structs are used to create complex data types that group different properties together.

Benefits of Using Structs in Go
Encapsulation: Structs help in encapsulating data. By grouping related fields together, they provide a way to model real-world entities more effectively.
Organization: They improve code organization by allowing you to logically group related properties. This makes the code more readable and maintainable.
Type Safety: Structs provide compile-time type checking, which helps in avoiding many common errors that could occur in dynamic languages.
Methods: Structs can have methods associated with them, which allows for better organization and separation of concerns in your code. Methods can operate on the struct’s data, enabling object-oriented programming features in Go.
Flexibility: Structs can be nested, meaning one struct can contain another struct as a field. This allows for complex data structures.
Memory Efficiency: Since structs in Go are stored contiguously in memory, they are more memory-efficient compared to maps or other data structures that use pointers.
