I was reading the Wikipedia entry on bit-fields, and saw how one might use binary numbers to represent primary colors and combine them using bitwise O ...

I thought this should work, but I'm obviously wrong, but I don't know why :-) Assume I had the following bytes from the network 0x03 0x02. In my head, ...

I dont understand why the output of this code is 4 and not 16, Assuming that unsigned int takes 4 bytes and long int takes 8 bytes. Any help? ...

So, I'm writing a struct that's going to be used for de-serializing a binary stream of data. To get the point across, here is a cut-down version: typ ...

I have been researching some code in c++ in unreal engine and I came across that they have on a header file 4 booleans declared as: bool bIsEvaluatin ...

First a bit of context : I want to process various documents and detect for each one which european countries have been mentioned. Example : EU_COUN ...

I have a problem to solve and I have no idea on how to go about it. I'm asking for a general idea on how to go about this. I have a memory address, in ...

I'm trying to use memcpy to copy part of an unsigned int to another unsigned int within the same struct I made. But my program only prints the first p ...

I'm trying to implement a constant linked DMA descriptor list (in ROM) on an Silabs EFR32BG22, where the last descriptor links to another descriptor l ...

Code Output: I was expecting 4 bytes to be assigned for x since the long int is bitfielded, 33 bits -> 4 + 4 bytes are assigned to it b ...

At the outset, I realize what I did was bad. I relied on what is now (at least) undefined behavior, if not explicitly forbidden. It used to work, and ...

This is an optimization problem. I want to copy a bitfield of six 5-bit elements to a u8 buffer, naively done like this: void Expand(u32 x, u8 b[6]) ...

Also this is my first time using stack overflow so this sorry if this goes wrong! ...

Lets say I have a bitfield structure: And lets say I have set the bits like this: Now, I want to separate the bitfield into two parts of 5 and 5 ...

For some reason I have a struct that needs to keep track of 56 bits of information ordered as 4 packs of 12 bits and 2 packs of 4 bits. This comes out ...

output: sizeof(dbits) = 16, but if Output: sizeof(dbits) = 8 Why does the size of the union increase? In the first and second union, the same n ...
