Golang program to print pointer to a struct
In this article, we will write Golang programs to print pointer to a struct. A pointer stores the address of the memory location where the variable’s value is placed. We can the access the address of the variable using & operator. For ex= &a tell the address of the a.
Example 1
In this example, we will write a Golang program to show the pointer to a struct by creating a child struct and printing the pointer to that struct.
package main
import "fmt"
type Child struct {
name string
age int
}
func main() {
c := &Child{"Varun", 15}
fmt.Println("Pointer to struct is: ", c)
}
Output
Pointer to struct: &{Varun 15}
Example 2
In this particular example, we will write a Golang program to print pointer to a struct using the & operator which depicts the address.
package main
import "fmt"
type Child struct {
name string
age int
}
func main() {
c := Child{name: "Veronica", age: 10}
fmt.Printf("Pointer to struct is: %p\n", &c)
}
Output
Pointer to struct is: 0xc0000b2018
Example 3: Golang Program to Print Pointer to Struct Using Person Struct
In this example, we will write a Golang program to print pointer to a struct using the Person struct. The pointer to the struct will be stored inside the variable and then printed on the console.
package main
import "fmt"
type Person struct {
name string
age int
}
func main() {
ps := Person{"Kalindi", 26}
ptr := &ps
fmt.Printf("The Pointer to struct presented here is: %p\n", ptr)
}
Output
The Pointer to struct presented here is: 0xc000010030
Conclusion
We compiled and executed the program of referring pointer to a struct using three examples. In both of the examples we created a child struct but in the first example, we printed the pointer to the struct and in the second example, we printed the address of the pointer to the struct and in the third example we used a Person struct to execute program.
