Function to print binary representation with leading zeros and spaces

int main
Decoding table
struct Entry table;
Read the number of entries in the decoding table
unsigned char Thex;
scanfx &Thex;
Interpret Thex as an unsigned integer
unsigned int T Thex;
If T is interpret it as
if T
T ;
Read and populate the decoding table
for int i ; i T; i
unsigned char c c c;
Read each byte individually
scanfhhx hhx hhx &c &c &c;
tableicharacter c;
Correctly extract the length using bitwise AND and shifting
tableilength c & xF;
tableiencoding c & xF c;
Read four bytes encoding the length of the compressed bitstream
unsigned int compressedLength;
unsigned char b b b b;
scanfhhx hhx hhx hhx &b &b &b &b;
compressedLength bbb b;
if compressedLength
Output the decoding table in the specified format
for int i ; i T; i
printfxx : d tableicharacter, tableilength;
Use the printBinary function to print the binary representation
printBinarytableiencoding, tableilength;
printf

int numDecoded ;
int done ;

unsigned char hexValue;
scanfhhx &hexValue;

binaryRep;
int bitstreamLength sizeofbinaryRep; Exclude the null terminator
Variable to represent encoding D
unsigned short currentEncoding ;
int currentLength ;
Process the bitstream
for int i ; i bitstreamLength; i
Read the next bit from the bitstream
unsigned char nextBit binaryRepi;
Add the next bit to the current encoding
currentEncoding currentEncoding nextBit;
currentLength;
printfu u
currentEncoding, currentLength;
int foundIndex ;
unsigned short accumalated ;
char arr;
int index ;
for int j ; j T && currentLength ; j
unsigned short bin binaryConversiontablejencoding, tablejlength;
accumalated accumalated bin;
printfu d
accumalated, tablejlength;
if tablejlength currentLength && accumalated currentEncoding
foundIndex j;
break;
if foundIndex
printfc tablefoundIndexcharacter;
Reset current encoding and length
currentEncoding ;
currentLength ;
Increment the number of decoded characters
numDecoded;
printfd
numDecoded;
ifnumDecoded compressedLength
done ;
break;
printf
;
return ;
here i am trying to concatenate the values of bin. for eg if bin for j is then accumulate will be then when bin for j is then accumulate becomes if for j bin is then accumulate becomes but it is not concatenating.
