Submitted by Nidhi, on July 02, 2021

Problem Solution:

Here, we will create a structure and pass the object of created structure to the function.

Program/Source Code:

The source code to create an array within the structure is given below. The given program is compiled and executed successfully.

// Swift program to pass a structure 
// to a function

import Swift

struct Str {
    var num:Int

    init(n:Int)
    {
        num=n
    }
}

func printNum(str:Str){
    print("Value of num: ",str.num)
}

var S = Str(n:10)

printNum(str:S)

Output:

Value of num:  10

...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 Str that contains an integer variable num. Then we initialized the structure with 10. We also created a function printNum() that accepts a structure as a parameter. The printNum() function prints the value of num on the console screen.
