What are the different types of data types in Go?

Data types in Go can be categorized into the following groups:

1. Basic Types:

   • Boolean type: bool (values are true or false)
   • Numeric types:
     • Integer types: int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, uintptr
     • Floating-point types: float32, float64
     • Complex types: complex64, complex128
   • String type: string

2. Composite Types:

   • Array type: Declares a sequence of elements with a fixed size and type, e.g., var a [5]int
   • Slice type: A dynamic-size version of arrays where the length is not specified at declaration, e.g., var b []int
   • Struct type: struct, which organizes different data types into a composite entity, e.g.,

     go
     type Person struct {
         Name string
         Age  int
     }

   • Pointer type: Used to store the memory address of a variable, e.g., var p *int

3. Special Types:

   • Interface type: interface, which defines a set of method signatures but does not implement them; other types implement these methods, e.g.,

     go
     type Shape interface {
         Area() float64
         Perimeter() float64
     }

   • Map type: map, which stores key-value pairs where keys and values can be of different types, e.g., var m map[string]int

4. Channel type (chan): Used for communication between multiple Go goroutines, e.g., chan int

Various data types support Go's powerful concurrency model and memory safety features, making it well-suited for systems programming and high-performance application development.
