Explain the use of Go structs for defining custom data types?

In Go, a struct is a composite data type that allows you to group together variables of different types under a single name. You can think of a struct as a way to create your own custom data type that is made up of other data types.
Here is an example of a simple struct in Go:
type Person struct {
name string
    age int
    occupation string
}

In this example, we define a new struct called Person, which has three fields: name, age, and occupation. Each field has its own data type, which can be any built-in or custom data type.
To create a new instance of this struct, we can use the following syntax:
person1 := Person{"John Doe", 30, "Software Engineer"}

In this example, we create a new Person instance called person1 and initialize its fields using a struct literal. We can also access and modify the fields of a struct using the dot notation:
fmt.Println(person1.name) // Output: John Doe

person1.age = 31
fmt.Println(person1.age) // Output: 31

Structs are commonly used in Go to represent complex data structures such as database records, network packets, and more. They provide a flexible way to organize and manipulate data in a program.
