Write a program that will print out all combinations that can be made when $2$ dice are rolled.

Your output should look like this:

$1,1$

$1,2$

$1,3$

$1,4$

$1,5$

$1,6$

$2,1$

$2,2$

$2,3$

$2,4$

And should continue until all values up to $6,6$ are printed.

Because you know exactly how many times each loop should iterate, you should use nested for loops to complete this program.
