Hello everyone.
I'm learning the go language and I have some questions regarding the
implementation of slices.
*$ cat slice_stack.go *
package main
import "fmt"
func main() {
stack_array := [4]int{1,2,3,4}
// !- I assume this is on the stack, like a local int[4] would be in C.
slice := stack_array[:] // Does this copy the data to the heap?
// or just get a slice to the mem on the stack?
for i := 0; i<25; i++ {
slice = append(slice, 99) // Does this copy the data to the heap on
first append?
}
fmt.Println(stack_array)
fmt.Println(slice)
}
*$ go run slice_stack.go *
[1 2 3 4]
[1 2 3 4 99 99 99 99 99 99 99 99 99 99 99 99 99 99 99 99 99 99 99 99 99 99
99 99 99]
Is it common to get slices to arrays on the stack? Am I wrong when I say
*stack_array* is on the stack?
Thank you.
