Following is a [C# program](https://www.mindstick.com/forum/156830/how-do-i-make-a-c-sharp-program-that-checks-for-given-array-by-user-which-elements-are-perfect-numbers) to [print 1 to 100](https://www.mindstick.com/forum/156826/how-to-print-1-to-100-number-without-using-any-number) number in format of 1 11 21.. using a single loop.

## Program:

```
using System;
class HelloWorld {
  static void Main() {
    int i=1;
    int j=1;
    while(i<=100)
    {
        if(i%10==0)
        {
            Console.WriteLine('  '+j);
            j++;
            j=j-100;
        }else
        {
            Console.Write('  '+j);
        }
        j=j+10;
        i++;
    }
  }
}
```

## Output:

```
1       11      21      31      41      51      61      71      81      91

3       13      23      33      43      53      63      73      83      93
4       14      24      34      44      54      64      74      84      94
5       15      25      35      45      55      65      75      85      95
6       16      26      36      46      56      66      76      86      96
7       17      27      37      47      57      67      77      87      97
8       18      28      38      48      58      68      78      88      98
9       19      29      39      49      59      69      79      89      99
10      20      30      40      50      60      70      80      90      100
