So I should use sprintf() outside of the while loop to initialize all filenames first? or did you mean I should use something else entirely?

Thanks for the help.

I'm using Linux as my primary system and clang as a compiler...

Anyway, thanks for the knowledge about dealing with slack space. As for searching blocks byte by byte at first, in the class we were...

The first condition for found and num makes sure I don't write anything to a file that isn't open (because I haven't found the first jpeg yet).

As to your second suggestion, that is definitely...

Hello guys,

I'm taking a CS course and we've been tasked with creating a program that recovers jpegs from a formatted CF card which uses the FAT file system with a block size of 512 bytes, the...

Done, I can probably check if the compiler optimized this already by looking at buffer's memory address, no?

Many thanks for the insights, I've understood what you meant about fread() and iterator and adjusted my code accordingly:



// loop over input file's scanlines
for (int i = 0,...

Now that I've actually fixed the algorithm I can throw the whole if-else construct away since it handles a factor of 1 correctly too.

Much thanks for the help... I've managed to tweak my algorithm to get it right.

Isn't that a job for the header file to handle? essentially since I say that width is say 6 pixels, the renderer will be expecting a width that is a multiple of 4, so it expects 6 pixels plus 2...

Well, now the new bmp file is even more messy than before... I'm really confused because I think I've translated my pseudocode correctly, maybe I need to approach the problem differently.

I did have some pseudocode, and it changed as I started coding, right now it goes like this:




loop over height of original bmp
loop over width of original bmp
store each pixel...

Hey guys,

I'm currently studying a CS course, and I have a problem set I can't seem to solve, we're required to make a small program that takes 3 arguments: (factor, file.bmp, file2.bmp) and...

Much thanks Peter for the explanation, I guess that's what Vladimir was trying to tell me but I didn't follow.

That's not the issue, it's when the program terminates, then I relaunch it again... I get maybe 3-4 repeated sequences if I place srand() inside the functions.

Hello guys,

I'm a new member here, and I'm currently trying to learn C++ by myself, I have some minor experience with programming through the C language.

I've been using a book to learn the...
