Does a 1C opening bid always require a response even if tere are no points or support?

How many cards and points does a strong jump shift response show on the first round?

What Justin said. Even though you do not have a fit, if you have nothing you should pass, for example with:

♠J843
♥J964
♦8632
♣5

the correct response to 1♣ is Pass.

A good suit with normally 6 cards and about 15 HCP, example minimum hand:

♠AKJ853
♥A83
♦K32
♣5

1♦ (Pass) 2♠

No.

There are peoble out there, who claim you have
to bid with nothing and shortage in clubs, but
they are wrong.
A response to 1C opner is a positive signal to partner,
you respond because you can respond, and not because
you have to respond.

You can play, that a 1C opener always requires a response,
but this would change your system in a fairly radical way.

Regarding your second question:

You need

#1 a good 5 card suit
#2 enough strength (HCP) for game oppossite a opener, say +12/13
#3 a clear idea, which game you want to play

Most of the time peoble forget #3, but this is nearly as
important as #1 and #2 combined.

Unless you know what #3 means, I would suggest, that you
never make a strong jump shift as responder, and I promise you,
that you will survive even if you dont jump.
There is no need to jump, new suits by responder are forcing,
and you give opener the most room to describe what he holds.

PS: I like strong jump shifts.

I had a partner who said i had to respond to his 1 c opening bid even though i had nothing

I had a partner who jump shifted with 14 points and 5 cards.

I learned that if i have less than 5 points as a response to 1 c opening bid I bid 1D whicjh is like pass and doesn't show D

There are systems out there, who have such a 1D
response, but in this case you no longer play Standard
American.

If a 1C opener cant be passed (fair enough), why have
a strong 2C opener, you can open all your strong hands
via 1C.

I wont recomment this, but if you play Standard American,
than 1C can be passed and a response to 1C shows some life.

Dpending on the hand this is fine, as long
as a simple non-jump response does not
deny a 5 card suit with more than 14HCP.

If your system catters for responder having nothing, ok. But in Standard American (and similar systems) you simply have to pass with most weak hands. Consider this:
1♣-1♦
?

With a 3334 and 13 points, you can't bid anything else than 1NT. With a 1336 and 11 points you can only bid 2♣.

With a 3334 and 18 points you cannot bid 2NT if p could be broke. You can only bid 1NT. For the same reason, with 17 points and a 1336 you cannot rebid more than 2♣.What is p supposed to do over a 1NT rebid that shows 12-14 or 18-19 points? Or a 2♣ rebid that shows 11-17 points?

A jump shift takes away a lot of bidding space. So it has to have a specific meaning. Some play it as either a 1-suiter, or a 2-suiter with 5-card support for opener's suit. But playing a jump shift as any strong hand with a five-card or longer is a very bad agreement.

I would be less severe and say it is not currently in fashion rather than a very bad call.

After all, a lot of successful rubber bridge is played this way and it is how people used to bid.
