pointers1 example

A struct passed to function by value (copy) and by address (reference).

GitHub Webpage

PASS BY REFERENCE (MAKES POINTER IN FUNCTION)

Passing the address of a struct to a function (by reference),

b := person{"Jill", "female", 27}
changeNamePtr(&b)

So the function can now work on that original struct,

func changeNamePtr(p *person) {
    p.name = "Lisa"
}

In this case the name is changed from Jill to Lisa.
