What data types are available in Go?

In Go, there are several basic data types:

• Boolean: bool — accepts values true or false.
• Integer: int, int8, int16, int32, int64 and their unsigned counterparts uint, uint8 (alias for byte), uint16, uint32, uint64.
• Floating-point numbers: float32, float64.
• Complex numbers: complex64, complex128.
• Strings: string — an immutable sequence of bytes.
• User-defined types: structures (struct), interfaces (interface), arrays, slices (slice), maps (map), channels (chan).

Example of declaring variables of different types:

var a int = 10
var b float64 = 3.14
var c bool = true
var s string = "hello"
