We’ve defined our struct and created an instance, it’s time to use them. In this exercise, we will explore how to access and modify a struct’s variables.

Let’s say we have an instance of the Student struct:

john := Student{"John", "Smith", 14, 9}

We can access individual fields within struct using the name of the variable, a ., and the name of the field. We could access John’s first name like so:

fmt.Println(john.firstName)

We can change the value of a field with an assignment statement:

john.age = 15

John’s just turned 15!

Using field access and modification finally allows us to be able to use structs in calculations for our program.

Now let’s practice this concept!
