Here, we are going to demonstrate the nested while loop in Swift programming language.
Submitted by Nidhi, on June 08, 2021

Problem Solution:

Here, we will use the nested while loop to print numbers on the console screen.

Program/Source Code:

The source code to demonstrate the nested while loop is given below. The given program is compiled and executed successfully.

// Swift program to demonstrate the 
// nested while loop

var cnt1:Int = 1;
var cnt2:Int = 1;

while(cnt1<=3)
{
    cnt2 = 1;
    while(cnt2<=cnt1)
    {
        print(cnt1);
        cnt2 = cnt2 + 1;
    }

    cnt1 = cnt1 + 1;
}

Output:

1
2
2
3
3
3

...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 two integer variables cnt1 and cnt2, both are initialized with 1. Then we printed numbers on the console screen using the nested while loop.
