Swift program to demonstrate the nested while loop

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.
