For Example I have a binary of 52504 as 11001101000 11000 and I want First 6 (

Answer 1

void  f(short int last, short int first, short int myNr){
      //construct mask for last bits
      short int mask=0;
      for(int i=0;i>1;} 
      aux=myNr;  
      aux&=mask;
      aux>>last; // only first bits are left and shifted
}

you can add parameters to get the values out or something
