Rajeev,
Actually, i get data in hex bytes from a log file. I have to parse them or
analyze them according to some predefined rules or values.
For eg: a hex byte of 0xa4 is converted to binary as 10100100
Now, i have a file in which the values are predefined. It looks like
0xa4 => 10100100
in that MSB 1 stands for some abc
then the following bits 01 stands for cdf
then the remaining bits 00100 stands for xyz
(0/1) | 2 bits | 5 bits
abc | System name | Other details
System name Other Details
00 ujj 00000
01 cdf 00001 etc....
10 bbg
11 gtt
In the above example, the text is just an eg and not the actual text.
I get those 8 bits as a whole as hex byte which i need to parse and diplay
them bitwise.
Hope this explains better.

Dharshana,
The program you wrote here to convert the number to binary is good. In the
second one, I am not getting what is your intention correctly. You said you
what to convert 0=> abc,..... Can I know a little bit more.
