How to pass a structure to a function in Golang?

Problem Solution:

In this program, we will create a structure and then pass the Student structure to the user-defined function PrintStruct() to print the value of structure members on the console screen.

Program/Source Code:

The source code to pass a structure to the user-defined function is given below. The given program is compiled and executed successfully.

Golang code to demonstrate the example of passing a structure to a function

// Golang program to pass a structure to the
// user-defined function

package main

import "fmt"

// Declaration of structure
type Student struct {
	Id   int
	Name string
	Fees int
}

func PrintStruct(stu Student) {
	fmt.Printf("Student Information:")
	fmt.Printf("\n\tStudent Id     : %d", stu.Id)
	fmt.Printf("\n\tStudent Name   : %s", stu.Name)
	fmt.Printf("\n\tStudent Fees   : %d", stu.Fees)
}

func main() {
	var stu Student

	stu.Id = 101
	stu.Name = "Kapil"
	stu.Fees = 12000

	PrintStruct(stu)
}

Output:

Student Information:
        Student Id     : 101
        Student Name   : Kapil
        Student Fees   : 12000

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

// Declaration of structure
type Student struct { 
	Id int
	Name string 
	Fees int 
} 

func PrintStruct(stu Student){ 
    fmt.Printf("Student Information:")
    fmt.Printf("\n\tStudent Id     : %d",stu.Id)
    fmt.Printf("\n\tStudent Name   : %s",stu.Name)
    fmt.Printf("\n\tStudent Fees   : %d",stu.Fees)
}

In the above code, we created a structure Student and defined a user-defined function that accepts the object of the structure as an argument and prints the value of member on the console screen.

In the main() function, we created the object stu of structure and assigned the values to the members. After that, we called PrintStruct() function to print the value of structure members on the console screen.
