Yes. Undoubtedly someone can plz. help you out with that problem. I
suggest you start with your classmates, and if they don't know the
solution either, blag it off a sophomore. If all else fails and you're
really desperate, perhaps you could ask your teacher. Only after you've
done that, _and_ have at least some code to show for it, should you come
back here and ask for help, _not_ for a hand-out.

int i;

for (i=0; i < 1; i++) {
printf("A\nB A\nA B A\nB A B A\nA B A B A\n");
}

OK, perhaps that isn't so helpful. Why don't you give it
a try, and see what you come up with. This is a trivial
problem, you'd learn lots more by doing your own
homework. Post what you come up with if you still
need help, if you make a good try people will assist
you.

The output is going to be:

A
B A
A B A
B A B A
A B A B A i wanted to be in reverse fashion, that's okay , but
i wanted to use something like: (i = 5; i <= 1; i--);

If we really wanted to punish you, the best way to do it would be to
give you the code to solve the problem. You could turn it in, get
credit for it, and learn nothing.

You should have local resources that can help you with this. Talk to
your instructor, to a teaching assistant, to fellow students. Try
writing the program yourself. Learn.

That would be an undue hardship on ourselves as well, however, as then
any of us might have the misfortune of working for the successful
cheater. Pointy-haired bosses are made, not born
