K&R C Exercise Help
I've been going through the K&R C Programming Language book and I'm stuck on Exercise 2-6 which reads: Write a function setbits(x,p,n,y) that returns x with the n bits that begin at position p set to the rightmost n bits of y, leaving the other bits unchanged. I'm having trouble understanding the exact thing they're looking for me...
Unexpected bitshift results
I'm initializing an unsigned short int with a = 0xff (all bits are set). Then I assign b to a>>7 which should yield (0000 0001) and it does. However, the odd thing is that when I assign c to a<<7, it isn't equivalent to (1000 0000). I tested this by outputting 0x80 (which is 1000 0000) and c, but they aren't the same. Here is some code:...
What exactly is the textual representation of Binary data?
Sometimes when you download a compiled binary file with the wrong mime type or for example running the "more" command on a binary file you get a bunch of "garbly gook" for lack of a better term. For example this a snippet of what I see when I run "more" from the command line on a very simple C program compiled with gcc on OS X. <94>^^^...

Generically reading a well-formed binary file
I'm trying to read contents of a game's map/model files into a program for the purposes of writing a small model viewer and testing out some DirectX features. The model/map file formats are chunked in nature, and I know the format of these files. I can easily read the files by parsing through the individual chunks, using an approach like...

Run SQL query on a binary file?
My company has a legacy micro-simulation program that simulates a population and changes to that population over a period of years. For each year, the program produces a binary file with a record for each individual that holds their characteristics (e.g., age, maritial status, income ... about 20 fields). We currently have several ut...
What is the difference between plaintext and binary data?
Many languages have functions which only process "plaintext", not binary. Does this mean that only characters within the ASCII range will be allowed? Binary is just a series of bytes, isn't it similar to plaintext which is just a series of bytes interpreted as characters? So, can plaintext store the same data formats / protocols as bin...
Restoring from backup and binary
There are times when a table / database is dropped unintentionally. I have to check the date-time of the start position from the binary when the backup was taken. I do also have to check the date-time of the position where the "drop" statement is found. I do run the mysqlbinlog statement with those parameters. I can not use start-posit...

Removing lowest order bit
Given a binary number, what is the fastest way of removing the lowest order bit? 01001001010 -> 01001001000 It would be used in code to iterate over the bits of a variable. Pseudo-code follows. while(bits != 0){ index = getIndexOfLowestOrderBit(bits); doSomething(index); removeLowestOrderBit(bits); } The possible languages I'...
