hi all,
i have a program that 'll take an Ip address from the user and 'll search this IP address in a file.
now i open this file in binary mode.
the IP address will be in this form 169.254.28.233
shall i convert this address into hex before searching? as i'm searching in a file in binary mode?

also i need a function or a sub program that do this conversion, in order to write the output clearly

Not unless you stored it as hex.

>as i'm searching in a file in binary mode?
This has nothing to do with hexadecimal.

i don't understand!!!!!!
now the user 'll give this ip address, then it'll be from the type string.
the binary file has unsigned char, how can i search this ip address.

then i need a function that do this conversion for another thing

Obviously!

If it's in the form of a string, then read it back as a string and do a string comparison. What's so hard about this? The fact that you're using a binary oriented file is 100% irrelevant.
