What Data Types Does Go Use?

Go uses the following data types:

1. Basic Types:

• Boolean type: bool
• Integer types: int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, uintptr
• Floating-point types: float32, float64
• Complex types: complex64, complex128
• String: string

1. Composite Types:

• Arrays: Defined as var a [5]int
• Slices: Dynamic arrays, defined as var s []int
• Structs: Used to define and group data of different or same types, for example type Person struct { Name string; Age int }
• Pointers: Store memory addresses of variables, defined as var p *int
• Function types: Functions can be passed as values, for example func add(x, y int) int { return x + y }
• Interfaces: Define types with method sets, for example type Geometry interface { Area() float64; Perimeter() float64 }
• Maps: Collections of key-value pairs, defined as var m map[string]int
• Channels: Used for communication between multiple Go goroutines, defined as ch := make(chan int)

Using these data types, you can build and manage data structures, enabling modular functionality and concise code.
