Swift program to create a new structure object with existing object

Here, we are going to learn how to create a new structure object with existing object in Swift programming language?
Submitted by Nidhi, on July 01, 2021

Problem Solution:

Here, we will create a structure with two methods to set and print structure members. And, we will create an object of structure with an existing object.

Program/Source Code:

The source code to the new structure object with the existing object is given below. The given program is compiled and executed successfully.

// Swift program to new structure object 
// with an existing object

import Swift

struct Student {
    var id: Int=0
    var name:String=""
    var fees:Int=0

    mutating func setInfo(i:Int, n:String, f:Int) {
        id=i
        name=n
        fees=f
    }

    mutating func printInfo() {
        print("Student Information:")
        print("\tStudent Id  : ",id)
        print("\tStudent Name: ",name)
        print("\tStudent Fees: ",fees)
    }
}

var stu1 = Student()

stu1.setInfo(i:1001,n:"Rahul",f:8000)
stu1.printInfo()

var stu2 = stu1
stu2.printInfo()

Output:

Student Information:
        Student Id  :  1001
        Student Name:  Rahul
        Student Fees:  8000
Student Information:
        Student Id  :  1001
        Student Name:  Rahul
        Student Fees:  8000

...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift

Here, we created a structure Student with three fields id, name, and fees and created two methods setInfo() and printInfo(). The setInfo() method is used to set student information and printInfo() method is used to print student information on the console screen.

Then we created the structure object stu1 and set the student information using the setInfo() method. After that, we created one more structure object stu2 with the existing object stu1. Then we printed student information of the stu2 object on the console screen.
