Dice Roll Outcome Generation

In this problem, you are required to generate all possible outcomes of rolling two six-sided dice. There are a total of 36 outcomes because each die can show an integer from 1 to 6. The results must be printed to standard output with each outcome on a separate line and the two numbers separated by a single space.

The outcomes should be in lexicographical order: for each value of the first die from 1 to 6, the second die should iterate from 1 to 6 in increasing order.

Note: This problem does not require any input from STDIN.
