  1. In Topic: Raising to a negative power in C

    Posted 31 Jan 2016

    Also, raising to the negitive power is the same as the inverse of the result of raising the the positive power.

    x-n = 1 / xn
  2. In Topic: Winsock2 - IRC bot not connecting to server

    Posted 31 Jan 2016

    You need to call WSAStartup() before performing any networking in winsock. Typically this is the first function call in main

    WSAStartup = Windows Socket API Startup

    It's ridiculous, but necessary. Good ol' windows.
  3. In Topic: Passing float arrays resulted in wrong array size?

    Posted 28 Jan 2016

    Pointers are not arrays. The sizeof a pointer on a 32-bit system is 4 (bytes). You must pass the size of the array as a parameter to the function which you are passing the array to.

    void printArray(int *arr, int size) {
       while(size--) {
          std::cout<<*arr++<<" ";
    int main() {
       int arr[5] = {1,2,3,4,5};
       printArray(arr, sizeof(arr) / sizeof(arr[0]));
       return 0;
  4. In Topic: while multiple condition help

    Posted 27 Jan 2016


    false || ( this can be anything, the code will never get here)

    I think you mean the AND operator there. ^

    The OR operator is sometimes hard to think about, sometimes it's easier to negate the condition and see if the opposite makes sense (when the loop should break).

    Taking this condition
    ispunct(*s) || parser_comment_level != 0 || *s != '\0'

    Negating it will give
    ispunct(*s) == false && parser_comment_level == 0 && *s == '\0'

    This is the condition which must be true for the for loop to break, ask yourself, does this seem valid?
  5. In Topic: [C++] Number of Days in Year

    Posted 27 Jan 2016

    Just because you crammed all of the logical conditions onto a single line does not make the code more efficient or elegant, it makes it unmaintainable and sloppy.

    If you ever find yourself nesting ternary operators, there is a better way to do it.
