  1. In Topic: Calling a .bat in a C console app

    Posted 9 May 2014

    So if "system" does not work for you and you seem to be in some version of visual studio you might consider using the windows API to launch the program.

    ShellExecute should function pretty much like double-clicking the item. Again you have to know the path to the batch file.

    #include "Windows.h"
    int main()
    {
    	HINSTANCE hReturnCode = ShellExecute(NULL, NULL, "example.bat", NULL, NULL, SW_SHOWNORMAL);
    	return 0;
    }
    


    If you need even more power you can try using CreateProcess
  2. In Topic: converting string of ints to a vector of ints

    Posted 9 May 2014

    Converting a string of numbers into a vector of ints is, in programming parlance: Parsing.

    To parse something you must first understand the input format. Does you input look like "12345" or "1,2,3,4,5" or "1\n2\n3\n4\n5" where \n is a new line?

    You have to be able to kind of "visualize" or understand what to expect as the input as that will define how you interpret the string.


    So if we are asking our user to enter a string like: "123432435" or even "1 2 3 4 5 6" and we want the vector [1,2,3,4,3,2,4,3,5] we can just grab the input one byte at a type and convert that byte to a numeric value:
    #include <iostream>
    using namespace std;
    
    int main ()
    {
    	char digit;
    	cout << "note: for this example you must press ctrl+c to end program" << endl;
    	cout << "Please enter a series of digits 0-9: ";
    	while(cin >> digit) {
    		cout << ((int)digit - '0') << ", ";
    	}
    	cout << endl;
    	
    	return 0;
    }
    


    The big problem with this program is that it does not know when to quite. Because we are running cin in a loop (and cin is ignoring white space) we can't really tell when we have reached the end of our input. We *could* just ask the user to end the input with a specific character and that would work but that might confuse the user.

    So it would be a little more helpful if we could look at the individual character in the input stream rather than than what >> gives us. cin.get© can do that for us.
    #include <iostream>
    #include <vector>
    #include <cctype>
    using namespace std;
    
    int main ()
    {
    	vector<int> digits;
    	char digit;
    	cout << "Please enter a series of digits 0-9: ";
    	while(cin.get(digit)) {
    		if (digit == '\n') { break; }
    		if (isdigit(digit)) {
    			digits.push_back(digit - '0');
    		} else if(isspace(digit)) {
    			//no operation
    			//ignore white space...
    		} else {
    			cout << "error in input" << endl;
    			break;
    		}
    	}
    	cout << "[";
    	for(vector<int>::iterator i = digits.begin(); i != digits.end(); ++i) {
    		cout << *i << " ";
    	}
    	cout << "]" << endl;
    	
    	return 0;
    }
    


    this little program lets the user enter things like:
    123432345542340980234598345968234087
    or
    234 3456098 ........0928304986

    when the user presses enter (or inputs an invalid character) the program terminates and displays what input it did read.
  3. In Topic: I want to write some binary code

    One of my main ambitions in life is to refute Godel's theorems. They're so obviously false, I can't believe anyone believes them.


    This literally made me choke! Classic comedy spit-take style!

    While I have read various dubious interpretations and exaggerated claims associated with Gödel's works this is a first for me. Usually people attack the various conclusions drawn rather than the work itself.

    As a mathematics student who worked though Gödel's proof I don't really think you stand much of a chance as Gödel was quite meticulous. He has, without out a doubt, done what he set out to do and no amount of wishful thinking on your part is likely to change that.

    HOWEVER, what Gödel did is actually pretty specific. People often take various degrees of an anarchist view of the implications and I think there is plenty of room to refute various claims on these but attacking Gödel will be difficult.

    In fact I would say that if you were successful you may find that you undermine a great more than just logic's rock-star's Theories. Indeed you may dismantle the very "mathematical hocus-pocus" on which they are based.

    However, to the guy building this upon Excel I warn: Gödel was convincing enough to win over the worlds deepest thinkers. You plan to use Excel to refute him?

    As a brilliant programmer one of the harder things I have to do is admit that the compiler is right. I can not tell you how many time I have been CONVINCED that my logic was infallible that things SO SIMPLE it could not possible be incorrect - the correctness of my program was self evident!!! And yet, the compiler (obviously programmed by a bunch of hacks) tells ME that it is WRONG!

    I have honestly wanted to beat monitors with bats, I have yelled at the screen in frustration, and once or twice I may have hit something or another.

    So far the score is something along the line of: Compiler - 45632, me 3.

    I am not saying that it is not possible that you are right, but I can assure you that if you feel Gödel's theorems are, "so obviously false, I can't believe anyone believes them." Then you had BETTER check your assumptions because I can assure you that there is a 99.999999999999% chance you have made a mistake somewhere in your thinking. You MAY BE RIGHT - but chances are not good. Check your assumptions.
  4. In Topic: I want to write some binary code

    Posted 5 May 2014

    @leibniz76 - While it is perfectly possible to write in binary, for modern PC's it is a bit prohibitive due to compounding complexity of a modern PC.

    Emulators are a good solution as you can strip away the OS level and interact directly with hardware. However modern PCs are still pretty complicated.

    Might I suggest Micro-controllers. #1 you can still use emulators for the bulk of your research and #2 you get a simplified version of what is going on in a PC.

    HOWEVER: While there is much to be learned in low-level programming what it DOES NOT DO is give you a very clear view of what is possible within programming a modern PC. Abstraction layers are extremely powerful and there is generally the idea that if you can't solve a problem you just need a higher level of abstraction - while this may not ALWAYS be true, very often it is. So just because it seems that something is not possible because the underlining system does not "support it" does not mean that the underlying system can not support some abstraction that CAN support it.
  5. In Topic: Job title?

    Posted 5 May 2014

    This is what I did as well. Kind of a general search of requirements for different positions.

    I get the feeling it is kind of a BA+Developer role.

    Analyst is such an overloaded term these days. Our support people are "Application Analysts" -- rather than the former "Support Engineers" -- its all very confusing.

    I don't really check my profile very often. So this is a really poor way to get my attention.

    grep is a function (generally in linux/unix) that searches though files using regular expressions. - The expression "You can't grep dead trees." is a disdain for printed manuals (you of course can grep man pages but not a printed manual).

    You should be like, a teacher or a tutor or something because you can Seriously communicate with students . . . Unless you already are one. I wouldn't be surprised if you were a college lecturer or something. :)

    @PlasticineGuy -- I don't mean to pick on anyone (usually).
    @ishkabible -- I have only really been posting in one forum so I don't expect it to last.
