Actually the JDS is simply a branded version of the GNOME desktop which is written entirely in C, together with programs most of which are written in C (StarOffice, Evolution, Mozilla). Despite the...

You do have got well over 1GB of RAM on you computer, right?
There's a much simpler solution that involves solving only one quadratic equation.. to obtain points where the line crosses the circle, substitute y = 2x + k in the circle's equation x²+y²-2x+4 = 0....

in my opinion tests like this tend to be more readable if you don't change the direction of the comparisons and write "myint is between 10 and 20" as "10 <= myint && myint <= 20". It looks more like...
You don't seem to be getting what the union of two sets really is...
The union contains all of the elements from both of the sets. Therefore the union is easily constructed by inserting all of the...
The union of two sets is the set that contains all of the elements in the two sets. You can construct the union by first making an empty set and then inserting into it all elements from one set and...
Well, like it says, the compiler is expecting to find a ")" before the word "result" on line 56. It doesn't get plainer than that. You are missing a closing parenthesis.
Have you tried it?
Is your class called stringset or StringSet? You use both.
The function is declared to return StringSet but you don't have a "return" statement.
> result = contents[i];
Instead of setting result to contents[i], you want to insert contents[i] to the result. So something like
result.insert(contents[i]);
Hint: suppose your set is A = {a1, a2, ..., aN}. Suppose P(A) is the set of all subsets of A.
Then P(A) = subsets of A that don't have a1 + subsets of A that do have a1, or:
P(A) = P(A\{a1}) +...
Have you done any programming at all before?
C++ might not be the easiest programming language to learn first. Learning to program is more about learning how to handle variables, conditional...
The intersection of two sets is the set that contains the elements that are present in both of the two sets. That is, if c is an element in "this" set, then c is in the intersection if and only if...
Instead of "test.txt" you use argv[1]. But of course you should first check that there is a command line argument, so
if (argc > 1)
{
infile.open(argv[1]);
}
else
{
tell the user s/he...
The code compiles with some warnings and produces this output:
09:25 ~> g++ -Wall stupid.cpp
stupid.cpp: In function ‘int main()’:

1) Optics and lots of linear algebra and numerical math. You can use formulas you find from the internet but if you actually understand it all you'll have fewer problems. You will need to know how to...
You CAN do RSA with small numbers, too. What happens is that it's much easier to crack.
In the heart of RSA is modular exponentation. You don't calculate it by first taking the exponent and then...
> A j[] = {A(1),B(2)};
This is the same as
A j[] = {A(1),A(B(2))};
Note that an object of B is created to initialize an object of A and then promptly thrown away. If you printed something from...
What are you really trying to do?
If you could compile the code you posted, what do you think happens when you create an object of A1? It will create an object of B2, which in turns creates an...
> imag1= (((sqrt(b*b-4*a*c))/(2*a))) ;
Here bē-4ac is negative, so you are calculating the square root of a negative number. You need:
imag1= sqrt(-d)/(2*a) ;
(You had already calculated d =...
This prints out $12,345.68:
std::cout.imbue(std::locale("en_US"));
std::cout << std::fixed << std::setprecision(2);
std::cout << "$" << 12345.678 << std::endl;(Don't forget that...
> ~AminaRPGEngine():
You wrote a colon there, it should be a semi-colon.
Either you declare a local xrot variable so "xrot" there is not the global xrot, 'key' is never 'x', or you reset the value of the xrot variable after the assignment.
You shouldn't be using a...
Thanks SlyMaelstrom and MadCow, strerror does seem to work even though I had doubts about it.
It doesn't seem to co-operate with exceptions though. Is there a way to get a meaninful error message...
