    The outer loop seems useless. Seeing that the inner loop is some kind of busy loop that waits for the value of m_finished to change, and judging by the name WAIT_FOR_PERIPH, I'd say this snippet...

    Indeed, using the equality operator on two arrays is perfectly valid C, although it would only produce the desired result if those two arrays were actually the exact same array in memory. That...

    Why are you saving the integer inside the char array? Why are you passing "sizeof(char*)" as the size?

    Btw, you don't want to use "char" for the types of size and left/right. "int" would be much...

    Initializing an array of structs is similar to a multi-dimensional array:

    They way I do it is to have two variables, one for the allocated size and another for the used size. When the used size equals the allocated size, it's time to allocate new memory.

    Use fgetc() and fputc() instead. Or better yet, at a lower level, use fread() and fwrite() with the buffer.

    If you don't worry about punctuation, reading words is just:

    scanf("%s", wordStr);

    For the reversing of each word, an easy implementation would be to use recursion. Or you could implement your...

    Do you have any proper documentation for the language and the compiler? I'm sorry, but that link is awful. You can't expect us to understand how it works just by showing some random examples. A wiki...

    Because "%c" is special, in the way that it doesn't ignore whitespace. If you want it to, you need to add a space before the percent sign, like this:


    scanf(" %c", &ch);

    It seems like a typo here, both should be like line #14. Let me explain:

    In line #10, "p" is used like an array of pointers.
    In line #14, "p" is used like a pointer to an array.

    Line #13 (declaration inside the for statement) is C99, although all compilers support it as an extension regardless. You should be using C99 anyway, all compilers support it (if yours doesn't, don't...

    So, you want multiple weapons to match on the same key? You can't do that with a map, I don't think. What you need is a multimap.

    It is indeed a nice forum. When I joined, back in 2009, Salem, Laserlight, Phantomotap and other regular members helped me quite a bit in becoming a better programmer.

    You need to point netbeans to the bin and lib directories of cygwin. I don't remember, but I though netbeans had an option to do that for you automatically.

    You're obviously doing something wrong at either the loading or the rendering phase. Without code, we can just guess.
