I try to put 8 int bit for example 10100010 into one character of type
char(1 octet) with no hope . Could anyone propose a simple way to do
it? Thank you very much.

It would help is we saw what you did. I would write:
unsigned char c = 0xA2; /* Hex A2 is 1010 0010 */
Not that unsigned char is almost always safer for this sort of thing.

thank you Ben. I have bit sequence 01010101.... that I want to
implement into a simulator, but in the simulator, they use a char as a
type of data since each int comprise between 24 octet and one char is
only 1 octet (=8 bits 0 or 1). I guess it will make the simulator run
faster, I'm not sure.

For your information, in C a char is not always an octet and there are
systems where the sizes of the various types can be quite surprising.
I don't think that affects your question, though.
I can't tell if I answered your question. If I did not, you need to
give much more information. Some actual code is often the best way
for people here to see what the problem is.

I think I'll have to try to understand the simulator first. it's a
very complicate network simulator with lots of code :(. I will try to
implement what you suggested and will post the code if I have further
information. thank you very much.

Do you mean that you have eight integers but that each one has either the
value 1 or 0? In that case, do:
Estce que vousvoulez dire que vous avez huite integers et que chaqun
d'entre eux a le valeur 1 ou 0? En ce cas, faitez:
int integers[8];
unsigned char character;
character= ( integers[0] ? (1 << 0) : 0 )
 ( integers[1] ? (1 << 1) : 0 )
 ( integers[2] ? (1 << 2) : 0 )
 ( integers[3] ? (1 << 3) : 0 )
 ( integers[4] ? (1 << 4) : 0 )
 ( integers[5] ? (1 << 5) : 0 )
 ( integers[6] ? (1 << 6) : 0 )
 ( integers[7] ? (1 << 7) : 0 );
Actually this works if the integers have the value 0 or non0. If you
are certain that they can only be 1 or 0, the following may be faster:
Ceci marche si les integers ont les valeurs 0 ou non0. Si vous etez
certain que ils n'ont que 1 ou 0, le cidessus peutetre plus vite:
character= (integers[0] << 0)
 ( integers[1] << 1)
 ( integers[2] << 2)
 ( integers[3] << 3)
 ( integers[4] << 4)
 ( integers[5] << 5)
 ( integers[6] << 6)
 ( integers[7] << 7);

Calling herself 'petitmouton' is a clue.
