What data types do you know in Go?

In Go, there are several basic data types:

• Boolean: bool (true/false)
• Integer types: int, int8, int16, int32, int64, as well as unsigned uint, uint8 (alias byte), uint16, uint32, uint64
• Floating-point numbers: float32, float64
• Complex numbers: complex64, complex128
• Strings: string
• Byte slices: []byte

Besides the basic types, there are composite types:

• Arrays and slices
• Structs (struct)
• Maps (map)
• Interfaces (interface{})
• Channels (chan)

Example of declaring variables:

var a int = 10
var b float64 = 3.14
var c bool = true
var s string = "hello"
var arr []int = []int{1, 2, 3}
