bookCreating Instances of Structs

In the previous chapter, we learned how to define a structure. However, the definition serves as only a blueprint, specifying how data is stored in an instance of that structure.

An instance of a structure is essentially a variable with the structure as its data type. Since it's a variable, data can be stored and modified within it.

Consider the following example of the Person structure from the previous chapter:

index.go

index.go

copy

              
12345

            
type Person struct {
    name string
    age int
    salary float64
}

We can create an instance of Person using the following syntax:

index.go

index.go

copy

              
1

            
var person1 Person

Note

In code, the structure must be defined before its instances are created.
