The following code creates a usable instance of the struct, Car
. How is this different than using new(Car)
?
Example:
type Car struct {
make string
}
func Main() {
var car Car; // how is this different than "car := new(Car)"?
car.make = "Honda"
}
One defines a Car variable, the other returns a pointer to a Car.
var car Car // defines variable car is a Car
car2 := new(Car) // defines variable car2 is a *Car and assigns a Car to back it
car := new(Car)
can be implemented in relation to var car Car
like this:
var x Car
car := &x
