Creating 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
12345type Person struct { name string age int salary float64 }
We can create an instance of Person
using the following syntax:
index.go
1var person1 Person
Note
In code, the structure must be defined before its instances are created.
