çıktısını nasıl alabilirim ?

I do not know your language but I have written some code.:)

#include <array>
#include <algorithm>
#include <iterator>
#include <iostream>

int main()
{
	std::array<int, 3> a = { 1, 3, 5 };

	for ( int i = 0; i < 4; i++ )
	{
		std::copy( a.begin(), a.end(), std::ostream_iterator<int>( std::cout, " " ) );
		std::cout << std::endl;

		std::transform( a.begin(), a.end(), a.begin(),
			[]( int x ) { return ( 10 * x + x % 10 + 1 ); } );
					            
	}
}

EDIT: to simplify the code you can change std::array<int, 3> a to usual array definition int a[] and correspondingly change a.begin() and a.end() to std::begin( a ) and std::end( a ) everywhere in the code.

Thanks a lot for you help.

edit : Would you kindly write array without using?

Would you kindly write array without using?

I have not understood what you mean, Do you mean to use an usual array? If so then the code will look the following way

#include <iostream>

int main()
{
	const int N = 3;
	const int base = 10;
	int a[N] = { 1, 3, 5 };

	for ( int i = 0; i < 4; i++ )
	{
		for ( int j = 0; j < N; j++ ) std::cout << a[j] << ' ';
		std::cout << std::endl;

		for ( int j = 0; j < N; j++ ) a[j] = base * a[j] + a[j] % base + 1;
	}
}

By the way if it is required that after digit 9 there will be digit 0 then the main expression can be rewritten as

a[j] = base * a[j] + ( a[j] % base + 1 ) % base;

If to use std::string then the code can look as

#include <iostream>
#include <string>

int main()
{
	const int N = 3;
	const int base = 10;
	std::string s[N] = { "1", "3", "5" };

	for ( int i = 0; i < 20; i ++ )
	{
		for ( int j = 0; j < N; j++ )
		{
			if ( i != 0 )
			{
				s[j].push_back( ( s[j].back() - '0' + 1 ) % base + '0' );
			}
			std::cout << s[j] << ' ';
		}
		std::cout << std::endl;
	}
}

The output:

1 3 5
12 34 56
123 345 567
1234 3456 5678
