Go Data Types
In programming, a data type defines the kind of data a variable can hold, including its size and how it's stored in memory.
Go is a statically typed language, which means each variable must be assigned a specific type, and that type cannot change.
Go supports three primary categories of data types:
- bool: Represents a boolean value (true or false)
- Numeric: Includes integers, floating-point numbers, and complex numbers
- string: Represents a sequence of characters
Example:
Using Different Data Types in Go
package main
import ("fmt")
func main() {
var a bool = true // Boolean
var b int = 5 // Integer
var c float32 = 3.14 // Floating-point number
var d string = "Hi!" // String
fmt.Println("Boolean:", a)
fmt.Println("Integer:", b)
fmt.Println("Float: ", c)
fmt.Println("String: ", d)
}
package main
import ("fmt")
func main() {
var a bool = true // Boolean
var b int = 5 // Integer
var c float32 = 3.14 // Floating-point number
var d string = "Hi!" // String
fmt.Println("Boolean:", a)
fmt.Println("Integer:", b)
fmt.Println("Float: ", c)
fmt.Println("String: ", d)
}
Output:
Boolean: true
Integer: 5
Float: 3.14
String: Hi!
Integer: 5
Float: 3.14
String: Hi!
