「Go言語」len()、unsafe Sizeof()メソッドを使うサンプル
書式
const identifier [type] = value
const c_name1, c_name2 = value1, value2
const (
定数名1
定数名2
)
使用例
package main
import "unsafe"
const (
x = "arkgame"
y = len(x)
z = unsafe.Sizeof(x)
)
func main(){
println(x, y, z)
}
package main
import "unsafe"
const (
x = "arkgame"
y = len(x)
z = unsafe.Sizeof(x)
)
func main(){
println(x, y, z)
}
package main
import "unsafe"
const (
x = "arkgame"
y = len(x)
z = unsafe.Sizeof(x)
)
func main(){
println(x, y, z)
}
実行結果
