The initialization of a struct in the go language.

The go language is no more than other languages, and in a struct, it has no constructors and does not have to be assigned or error-free.

Like what:

struct {        string  ageint}func main () {    var  P Student    FMT. Println ("Theperson'snameis", p.name)    FMT. Println ("the person'snameis", P.age)}

This is why, because when you name a type, string defaults to NULL, and the int type defaults to 0,float64, which defaults to 0.0.

There are several ways to use it when initializing:

The first type:

    var P Student     " Huang "          fmt. Println ("Theperson'snameis", p.name)    FMT. Println ("the person'snameis", P.age)

The second type, direct:

    var P Student = student{"Huang"to    FMT. Println ("Theperson'snameis", p.name)    FMT. Println ("the person'snameis", P.age)

The third type:

New (person)

Note that the third new word represents a pointer.
