We express obligation when talking about things we have to do. Look at these examples:
Tengo que ir al colegio.
I have to go to school.
Tienes que comer sano.
You have to eat healthily.
Tiene que salir ahora.
He has to leave now.
Tenemos que salir todos los días.
We have to go out every day.
Note that when you use tener que + infinitivo it means to have to + infinitive.
You cannot omit que!

Do you mean, "hace falta comer" or "il faut s'alimenter"?
The difference is between obligation and necessity (or a want of something).

Hola Inma!
didn't need to (infinitive) & needn't have (past participle) are used to express the lack of necessity in the past, however
didn't need implies that the speaker didn't do something because he/she new that it was not necessary
needn't have means the speaker did something and then he/she knew that it had not been necessary
for example:
I didn't need to have an interview because I had worked there before
I needn't have cooked dinner. Just as it was ready, Chris and June phoned to say that they couldn't come to eat
(examples are taken from Advanced Grammar in Use by Martin Hewings)
How can I express it in Spanish?
Regards,
Alexander
