Hello ..
I need some help to create a program that will do a function like , reading different value for the sensor,
e.g an arduino can receive different digital input , the controller should combine all this , and then convert it to HEX , and then sent this code to an another mobile no..
Can anyone can help me in making this program.

i think so , check the subsrction gigs & collaborations

and please be more specific because it is still vague what you want ....

As i am doing a project , so i want that the different switches status , mean On or Off , 0 or 1 , this is the digital input to the Arduino , then the Arduino combine the 10 different status of the switches,
like this 1000110000 ,,,, so this code is then converted to HEX format , and the HEX format should be sent by an GSM Modem or Mobile Phone..
So how can i do this !!!

Just collect the bits and put them in the right place using bitWrite - http://www.arduino.cc/en/Reference/BitWrite -

one integer can hold 16 bit so it can easy hold your 10 bits

Code:

int ALL = 0;
for(uint8_t i=0; i<10; i++)
{
  bitWrite(ALL, i, digitalRead(i));
}
Serial.println(ALL, HEX);

Please not this is only a code snippet, it is not a complete sketch. Therefor you will have to make a sketch out of it. But all the 'difficult ' parts you need are in there.

Please spend a few days on the tutorial section and the reference section as there is a lot to learn there. You will see many language constructs and how to do things like you asked. Time spend there is not time lost.

Succes,
