playing with Go runtime

main.go

package main

import "runtime"

func main() {
	var x [10]int
	var y = &x[2] //ref to array contetn
	var z = y     // ref copy

	println(&x, y, z) //will print reference memory address
	a(x)
	println(&x, y, z) //will print different reference memory address
	runtime.GC() //garbage collector call
	println(&x, y, z) //will print different reference memory address AGAIN
}

//go:noinline
func a(x [10]int) {
	println("func a")
	var y [100]int
	b(y)
}

//go:noinline
func b(x [100]int) {
	println("func b")
	var y [1000]int
	c(y)
}

//go:noinline
func c(x [1000]int) {
	println("func c")
}

Output example:

0xc00003a738 0xc00003a748 0xc00003a748
func a
func b
func c
0xc00007df38 0xc00007df48 0xc00007df48
0xc000075f38 0xc000075f48 0xc000075f48
