String Data Type in Go
- In Go, the string data type is used to store sequences of characters, also known as text. String values must be enclosed in double quotes (").
Example:
package main
import "fmt"
func main() {
var txt1 string = "Hello!"
var txt2 string // Declared but not initialized (defaults to empty string)
txt3 := "World 1" // Short variable declaration
fmt.Printf("Type: %T, value: %v\n", txt1, txt1)
fmt.Printf("Type: %T, value: %v\n", txt2, txt2)
fmt.Printf("Type: %T, value: %v\n", txt3, txt3)
}
Output:
Type: string, value: Hello!
Type: string, value:
Type: string, value: World 1
Note:
- A string variable that is declared but not initialized will have the default value of an empty string ("").
- You can use either the var keyword with a type or the shorthand := for declaring and initializing string
