the following code shows that the output in a linux-like operating system is 16 bytes, which is the same as officially, but in a windows environment, the output is 8 bytes? Excuse me, why is this?
package main
import (
"fmt"
"unsafe"
)
func main() {
var a = "hello world"
fmt.Print(unsafe.Sizeof(a))
}
you should install a 32-bit version under windows and a 64-bit version under linux, resulting in this difference. For a string, the 32-bit version will return 8-bit version and the 64-bit version will return 16.
the occupied space of a string should be a uintptr pointer plus the length of the string int , Windows32 bit version is 4x4 and Windows32 64-bit version is 8room8
