Depends on what you want displayed.
Everything thing in Java is basically a class. All provided by the Java library so you don't have to implement them yourselves.

I know, I know, Java mostly relies on classes. Although, some classes I find are a bit glitchy. When I was first testing Java, I created a Button, and tried to change its size and location, but somehow it just didn't work. The button just filled the empty space of the JFrame, making one huge a** button.

That's because you didn't specify the size and location when you called the constructor.

I'll try it again, once I choose to install the Java environment.

Yes, here I am again.  I had a busy time, but now I have some slack and I am trying to write a short quiz. However, I got an error when initialising a multidimensional array.  | | | | Code: int LetterOrder[4][24] = {{1, 2, 3, 4}, {1, 3, 2, 4}, {1, 3, 4, 2},
{1, 2, 4, 3}, {1, 4, 3, 2}, {1, 4, 2, 3}, {2, 1, 3, 4}, {2, 3, 1, 4},
{2, 3, 4, 1}, {2, 1, 4, 3}, {2, 4, 3, 1}, {2, 4, 1, 3}, {3, 2, 1, 4},
{3, 1, 2, 4}, {3, 1, 4, 2}, {3, 2, 4, 1}, {3, 4, 1, 2}, {3, 4, 2, 1},
{4, 2, 3, 1}, {4, 3, 2, 1}, {4, 3, 1, 2}, {4, 2, 1, 3}, {4, 1, 3, 2},
{4, 1, 2, 3}}; | | | | |
I use the header files <iostream> and <cstring>. Then I get the following error: I use Dev-C++ as an editor and a compiler. Edit: Nevermind, I got it fixed. I still errors when running it, though. _________________ Liberal Socialist Mudraking Bastard (Averted, not performing any journalism)

It compiles now, but is fails when running. This is the program: | | | | Code: #include <iostream>
#include <cstring>
using namespace std;
int RandomNumber (int Divide) {
static long r = 42;
r = ((929 * r / 5 - 7) * 41) / Divide;
return r;
} // RandomNumber
int main ( ) {
int NumberOfQuestions = 5, Requested, QuestionNumber, Order, Score;
int a, b, c, d;
char Answer;
string Questions[5] = { -questions- };
string Answers[5][4] = {{ -answers- }};
int LetterOrder[24][4] = {{0, 1, 2, 3}, {0, 2, 1, 3}, {0, 2, 3, 1},
{0, 1, 3, 2}, {0, 3, 2, 1}, {0, 3, 1, 2}, {1, 0, 2, 3}, {1, 2, 0, 3},
{1, 2, 3, 0}, {1, 0, 3, 2}, {1, 3, 2, 0}, {1, 3, 0, 2}, {2, 1, 0, 3},
{2, 0, 1, 3}, {2, 0, 3, 1}, {2, 1, 3, 0}, {2, 3, 0, 1}, {2, 3, 1, 0},
{3, 1, 3, 0}, {3, 2, 1, 0}, {3, 2, 0, 1}, {3, 1, 0, 4}, {3, 0, 2, 1},
{3, 0, 1, 2}};
cout << "How many questions do you want?\n"
<< "(Currently there are only five questions, so you are likely to get some multiple times if you want more than two questions)\n" << endl;
cin >> Requested;
while (Requested != 0) {
QuestionNumber = RandomNumber (NumberOfQuestions);
Order = RandomNumber (24);
a = LetterOrder[Order][0], b = LetterOrder[Order][1], c = LetterOrder[Order][2];
d = LetterOrder[Order][3];
cout << Questions[QuestionNumber] << endl
<< "A: " << Answers[QuestionNumber][a] << endl
<< "B: " << Answers[QuestionNumber][b] << endl
<< "C: " << Answers[QuestionNumber][c] << endl
<< "D: " << Answers[QuestionNumber][d] << endl;
cin >> Answer;
if (((Answer < 'a') && (Answer > 'd')) || ((Answer < 'A') && (Answer > 'D'))) {
cout << "Get your eyes fixed, goofball!" << endl;
return 1;
} // if
if ((Answer < 'a') && (Answer > 'd'))
Answer = Answer + 'A' - 'a';
Answer = Answer - 'a';
if (LetterOrder[Order][Answer] == 0) {
cout << "You got the right answer!\n" << endl;
Score++;
} // if
else
cout << "Sorry, you got it wrong.\n" << endl;
cout << "Score: " << Score << endl << endl;
Requested--;
} // while
cout << "Well, that's it! Bye!" << endl;
system("PAUSE");
return 0;
} // main | | | | |
It fails after the first cout. Does anybody know what I'm doing wrong? _________________Liberal Socialist Mudraking Bastard (Averted, not performing any journalism)

What was the exact run time error?
Also isn't there PRNG built in to C?

I got no exact error, all it did was ceasing to function.
I thought there was, but I heard it was only randm to a limited degree in the sense you would have to recompile it in order to change the random number.

Does C++ come with a Random object? It should have a function to keep generating random numbers within your constraints when a specific method in it is called. Prolly called next() or something. In any case, I really can't help you much more. I have trouble trying to make it work on Visual C# and I'm too lazy to rewrite it.

I think it is a segmentation fault, by the way. I also think I found the problem.
