    #71: Fortran 90
    Last Fortran for a while. I mean, there are literally dozens of ways to make the program look different (indexed I/O versus formatted I/O, different kinds of loops, loops controlled by arithmetic if statements, assigned goto statements, programs that use an array instead of just writing the loop counter, etc., etc., etc.), but how much of this quaintness can anyone be expected to stand?


    !  Fortran 90 No explicit loop, use formatted I/O
    !
    !  Zaphod_b
    !
            Program PrintSequence
     
            write(*,'(1x,i0)') (i, i=1,10)
            Stop
     
            End Program PrintSequence


    Cheers!

    showpage                     % Taa-daa!

    If you have a PostScript printer attached to a port on your computer (or a PostScript driver for a port) just copy (use "echo" or "type" or whatever...) this file to that port.

    Or...

    If you have GhostView (or gsview or some other spin-off) or some other utility that can display PostScript, use that to view it (and print from there if you really want to).

    Or...

    Use ps2pdf (a shell script using gs or ghostscript) to create a pdf file and look at it with the acroread Acrobat Reader or some such thing.


    Cheers!

    75: PostScript with a "for" loop

    A little more "interesting" PostScript program. (You did know that PostScript is a full-fledged programming language, not just a page layout markup language, right?)

    Shows some macros that make text a little "easier." The actual program is the single line "for" loop near the bottom.

    76: C with enums

    Notice that enums in C are are not exactly what a lot of people seem to think they are.
    #include <stdio.h>
     
    /* In C, an enum is an alias for an integer data type.
       There is practically no advantage to using them,
       and newcomers are surprised to find that you
       can't print out the name; just the integer value.
     
       Oh, well...
     
       Here's a way to print the integers 1-10.  I'm
       not sure that anyone on Planet Earth has ever
       done it exactly this way, but don't quote me on
       that.
     
       Zaphod_b
    */
     
    typedef enum
    {
        WinterDays, /* The 304-day Roman Calendar reserved 57 days between
                       December and January just for fun.  Ahhh.  Those were the days! */
     
        /* Now for the boring months of the English-language modern calendar */
         January, February, March    , April  , May     , June,
         July   , August  , September, October, November, December
    } months_t;
     
    int main()
    {
        months_t month;
     
        for (month = January; month <= October; month++)
        {
            printf("%d\n", month); /* The enum is really just an int, and that's what gets printed */
        }
        return 0;
    }

    Please note that this is a standard C program, but will not compile as a C++ program. For those ignorant people who are fond of spouting off the fallacy that claims "C++ is a superset of C," well, strictly speaking it is not. There are a handful of things that work in C that will not work in C++. This program and the next constitute my attempt to point out one of those things.

    77: C++ with enums

    #include <iostream>
    using namespace std;
     
    /* In C++, unlike C, an enum is really a different data type.
     
       You can't increment an enum variable with a '++' operator,
       but if you use an enum in an arithmetic expression with
       an int variable, the enum is "promoted" to an int.
     
       The int result will NOT be automatically converted back
       to an enum, but you can use a simple cast.
     
     
       Anyhow...
     
       Here's a way to print the numbers 1--10 using C++
       enums.
     
       Zaphod_b
    */
     
    // Note that you can use the old-fashioned C-style typedef
    // if you want to, but I'll use the more modern C++
    // declaration:
    enum months_t
    {
        WinterDays, /* The 304-day Roman Calendar reserved 57 days between
                       December and January just for fun */
     
        /* Now for the boring months of the English-language modern calendar */
         January, February, March    , April  , May     , June,
         July   , August  , September, October, November, December
    };
     
    int main()
    {
        for (months_t month = January; month <= October; month = (months_t)(month+1))
        {
            cout << month << endl; // Note that the << operator is overloaded to print the int value
        }
        return 0;
    }


    In a C or C++ program like this, there is no way (really: no way) to print out the name of an enum as a string just from the enum definition. Really.

    Bottom line: I think Java enums make a lot more sense, and I think they can certainly be more useful, in general, than C enums or C++ enums.

    From interaction with new Javaites (including my own newbie self): It seems to me that enums often don't work out to be as easily useful as people thought they were going to when the topic was first introduced.


    Cheers!

    79: Java with enums---a little different from the previous Java enum example


    Man! Once enums begin dancing around in my head(s) it's like the theme from the Andy Griffith show---I just can't stop whistling. (R.I.P, Andy. We love ya, man!)

    Anyhow...

    //
    // Zaphod_b
    //
     
    public class Z
    {
        enum Month{
            January   (1),
            February  (2),
            March     (3), 
            April     (4),
            May       (5),
            June      (6),
            July      (7),
            August    (8),
            September (9),
            October   (10),
            November  (11),
            December  (12);
     
            private final int monthNum;
     
            public int num() {return monthNum;}
     
            Month(int n)
            {
                monthNum = n;
            }
     
        }
     
        public static void main(String [] args)
        {
            // It may look kind of silly to do it this way, but
            // I'll just print the numbers 1-10.  That's the
            // drill, right?
            //
            for (Month m : Month.values())
            {
                if (m.num() >= 1 && m.num() <= 10)
                System.out.println(m.num());
            }
     
            // If we wanted to print corresponding month names...
            //
            //System.out.println();
            //System.out.println("Month names for the first ten months:");
            //for (Month m : Month.values())
            //{
                //if (m.num() >= 1 && m.num() <= 10)
                //System.out.println(m);
            //}
        }
    }

    for (my $i = 1; $i <= 10; $i++)

        print $i, "\n";
    }

    Tested with perl 5.8.8

    By the way:
    Whatever happened to all of those perl guys anyhow? I mean, at one time you couldn't swing a dead cat without hitting several perl wonks, but I haven't heard much from them lately (the perl guys or the dead cats either).

    Are they all developing Java apps for Android devices now or what? (I can believe that some of the Android apps were written by dead cats. Not so sure about the perl guys. The unlearning curve for perl is steeper than the learning curve, I'm thinking.)

    Well, by my count, the original number 18 had four errors. You corrected the "10 - 1" thing on line 8, right? So, by my count there are still three errors.

    1. Without any kind of statement about using std::cout or using namespace std, it won't compile with any of my compilers (GNU g++ with Linux, GNU/cygwin under Windows XP, two versions of Borland bcc32.exe and two versions of Microsoft cl.exe)

    2. Line 13 looks like this: cout << a* << " ";
    That does not compute. Surely it was supposed to be *a instead of a*.

    Fixing those things at least gets it to compile, but it does not print the numbers 1 through 10. (On my system it prints 0 through 9.) So we have arrived at bug number

    3. In fact there is undefined behavior, since, after the first loop, the variable a is pointing beyond the end of allocated memory.

    That means that the value of the first thing printed is garbage (may be zero for some compilers, something else for others, but its actual value is indeterminate according to the C++ language definition document). Then the other nine things printed are the last nine things stored, printed in reverse order, namely numbers 1 through 9.

    I respectfully suggest that the program can be "fixed" with a minor change or two, and its honored spot as number 18 on the list can be honestly preserved with something like the following:

    #include <iostream>
    // Fixes for number 18 suggested by
    //
    //   Zaphod_b
    //
     
    // The following is so that the compiler can know stuff about cout
    //
    using namespace std;
     
    int main()
    {
         int * a = new int[10];
         for (int i = 0; i < 10; i++)
         {
              *a = 10 - i;
              a++;
         }
     
         // Note that the variable a is now pointing beyond the end
         // of allocated memory!
     
         for (int i = 0; i < 10; i++)
         {
              cout << *(--a) << " "; // Decrement a before each access
         }
     
         // As a matter of personal style, I never return with the cursor
         // any place other than the beginning of the line.
         // 
         cout << endl;
     
         delete [] a;
     
         return 0;
    }

    Tested with GNU g++ version 4.1.2, among others, and memory access legitimacy validated with valgrind version 3.5.0

    Output

    1 2 3 4 5 6 7 8 9 10

    86: forth
    Well, after I dug up my old PostScript documents, and had so much with the Stack architecture, could forth be far behind?

    \ z.fs
    \
    \ gforth demo program to print numbers 1 through 10
    \
    \ Zaphod_b
    \
    : Counter 11 1 ?DO i .  LOOP ; ( Define the Counter word )
    Counter ( Execute the Counter word )
    cr      ( Print a newline after the numbers )
    bye     ( Exit back to command shell )

    Tested with gforth 0.7.0 on my Centos 5.8 Linux workstation.

    Just enter gforth z.fs at a command line prompt.

    Output

    1 2 3 4 5 6 7 8 9 10

    87: Java

    All right, a'ready. Enough of the non-Java stuff for a while. Maybe people here aren't really interested (much) in non-Java solutions, although I think it might not be too bad to color outside the lines once in a while (and the originator of this thread did say "no language boundaries" after all.)

    Anyhow...

    It's not really magic (not even close), but I think it may be a little weird to go to all that trouble just to print out the numbers 1 through 10

    //
    // It's really just plain old Java.  Nothing magical here.

                { 82232672,173679334},

            };
            for (int i = 0; i < magicalValues.length; i++)
            {
                System.out.println(magicalValue(magicalValues[i]));
            }
        }
     
        static int magicalValue(int [] x)
        {
            return O_0(x[0], x[1]);
        }

    One, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten

    Well, everyone else has been printing numerals made up of decimal digits, but the original post said "Numbers," so I'm thinking numerals made up of words is also valid (although I'm not sure that commas between the numbers comply with the original).

    I mean, if this were a "real" program specification, I would ask for clarification. Also I note that some of the contributions put them all on the same line and some put each one on a separate line. I'm thinking that both ways have been accepted without complaint.

    Anyhow... I think your scheme should be numbered 90 (unless I lost count somewhere, and that's entirely possible).

    Furthermore...

    If people want to stick to decimal digit-based numerals, they could just change your definition to
       public static final byte[] NUMBER_BYTES = { 
           0x31, 0x20, 0x32, 0x20, 0x33, 0x20, 0x34, 0x20, 0x35, 0x20,
           0x36, 0x20, 0x37, 0x20, 0x38, 0x20, 0x39, 0x20, 0x31, 0x30
       };

    Output

    1 2 3 4 5 6 7 8 9 10


    Now, with your main(), the old familiar 1 2 3 ... appears, and this one should be numbered 91. (I think).

    I'm not sure that original contributors are still following this thread, since there hadn't been much activity lately until I got caught up in it when all those numbers began flitting back and forth between my left brain and my right brain...


    Cheers!

    Or even briefer:

    public static final byte[] NUMBER_BYTES = {0x31, 0x20, 0x74, 0x6f, 0x20, 0x31, 0x30};

    93 (I think): Java

    // One "easy" way (without using the Math.pow function) is Newton's method

    94: Java (Tridiagonal matrix)

    The mission: The numbers 1, 2, ..., 10 are a solution looking for a problem.

    Here's another possibility:
    //
    // Solution of tridiagonal matrix system by Gauss reduction
    //
    // Reference   en.wikipedia.org/wiki/Tridiagonal_matrix_algorithm
    //
    //
    // Zaphod_b
    //
    public class z
    {
        public static void main(String [] str)
        {
            // Below main diagonal
            double a[] = {0.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0};
     
            // Main diaglnal
            double b[] = {4.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0};
     
            // Above main diagonal
            double c[] = {1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 0.0};
     
            // Right-hand side
            double d[] = {6.0, 12.0, 18.0, 24.0, 30.0, 36.0, 42.0, 48.0, 54.0, 49.0};
     
            int n = d.length;
     
            // Solution
            double x[] = new double[n];
     
     
            // Forward reduction
            c[0] = c[0]/b[0];
            d[0] = d[0]/b[0];
            for (int i = 1; i < n; i++)
            {
                double denominator = b[i] - c[i-1]*a[i];
                c[i] = c[i]/denominator;
                d[i] = (d[i] - d[i-1]*a[i])/denominator;
            } // End of forward reduction
     
            // Back substitution
            x[n - 1] = d[n - 1];
            for (int i = n - 2; i >= 0; i--)
            {
                x[i] = d[i] - c[i]*x[i+1];
            } // End of back substitution
     
            // Print out solution values as integers.
            for (int i = 0; i < n; i++)
            {
                // For debugging and/or insight
                //System.out.printf("%.16e\n", x[i]);
     
                System.out.printf("%.0f", x[i]);
                if (i < n-1)
                {
                    System.out.print(" ");
                }
                else
                {
                    System.out.println();
                }
            } // End of printout
        } // End of main()
    } // End of class definition

    Output
