    Re: Optimizing jpeg recovery code

    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.

    Re: Optimizing jpeg recovery code

    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...

    Optimizing jpeg recovery code

    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...

    Re: Resizing BMP Files

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

    Re: Resizing BMP Files

    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,...

    Re: Resizing BMP Files

    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.

    Re: Resizing BMP Files

    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...

    Re: Resizing BMP Files

    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.

    Re: Resizing BMP Files

    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...

    Resizing BMP Files [Solved]

    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.
  15. Re: Simulation: Tortoise & Hare race (srand question)

    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.
  16. Simulation: Tortoise & Hare race (srand question)

    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...
