| | Oh good, another futile "War on ...." initiative. I wonder how the US is managing with the "War on drugs" ([url]http://www.drugsense.org/wodclock.htm)[/url]. Now that's a lot of moola. Still, it makes good PR for the chattering classes even if nothing ever comes of it. Even in the midst of failure, they … |
 | Worse is to come. Guess what's going to get sliced to the bone in the downturn? Yep, that's right, anything for which a bean-counter can't see having an immediate monetary value which can be bought or sold. Security fits ever so snugly into this category. Another example is quality. Sure, …  |

| | Big Brother is shit. Big Brother in HD would be HD shit. Big Brother in 3D would be 3D shit. Then there's the "repeats", the "making of", the "talk show" and the "uncut" versions to deal with. 100s of hours of airtime filled for a pittance of production budget. The … |

| | So have you done 'ls' without the -R part already? Use the stat() function to work out what kind of thing a directory entry is, then call your file listing function recursively.  |

| | Use fgets() to read each line. Use sscanf() to parse the line (or better yet, strtod). |
| | Well it rather depends on the application. Web browsers for example just give up and print a message. A file downloader might retry. |

| | Re: cmd window The console is what you learn with. GUI programming is no different, it's just a different API. But it takes half a book to explain "hello world" rather than half a page, to an absolute newbie.  |
| | What you see today in the C pre-processor is a faint echo of how the pre-processor was originally implemented. [URL="http://en.wikipedia.org/wiki/M4_%28computer_language%29"]m4[/URL] is a macro pre-processor and then plenty. The original C pre-processor (when C was still on a single machine in the 70's) was just an input to m4. Oh, but … |

| | One function to write the struct to a file. Another function to read the struct from a file. For each field, use the appropriate fprintf or fscanf conversion function. For extra robustness on reading, use fgets() to begin with. |

| | Well you need to build into your loop some sense of "expecting number" and "expecting operator". It should toggle between these two states. So if you're expecting a number, and see '-', you know what it means. |

| | Which end of the list holds the least significant digits? Adding 12 to 3456 for example, adds 2 and 6 together because they're the same rank at the end of the list. Not adding 1 and 3 together because they're at the head of the list. |
