A massively multilayer online..... what?

loop using (while) i got a problem with the declaration in C and C++

David W — Wed, 15 Oct 2008 13:00:47 -0600

[quot]thanx alot =)

But why does the process repeat itself again automatically ?
Is that because " goto testing " ?
[/quote]

Yep .... just remove both 'TESTING' lines ...'

That 'forever loop' was just put in for testing purposes. You could name your labels using any valid variable name. The label has a colon after it to tell the compiler that it is a label. Colons have several meanings in C/C++ and depending on context, the compiler will try to do what it knows to do ... Otherwise ... it reports an error condition.

The label name I used was TESTING: It has a colon ':' at the end, to let the compiler know that it is a 'label', (actually an address in memory, that now goes by that 'handle'.)

The 'goto TESTING;' here is an unconditional jump, i.e. it ALWAYS jumps to the label specified. This is a neat trick for debugging or testing code to jump over ... or back ... to some code ... and carry on from there.

'goto' is what we old programmers used to have to use to build all our structures. It is still MUCH used in assembly language where it is a jmp.

The nice structures you see like ... 'while' or 'for' are all made up of many jumps behind the scenes. High Level languages like C or C++ do a lot of work for you and the structures there are the way to go ... to write code that is much more readable ... and so much easier to get the logic right and to maintain. Some might say that you should never use a goto ... But that is a little extreme ...and may betray a lack of understanding of what is actually going on inside the CPU. Instead of such an extreme ... goto is seldom used except in debugging or testing. It is still good to keep 'goto' in your 'bag of tools'.

Shalom,

David

What is the difference between Computing Science/Software Engineering. in Computer Science

AdaHacker — Wed, 15 Oct 2008 12:58:20 -0600

Perhaps I can illuminate this with a quote on this topic attributed to the late Edsger Dijkstra, one of the fathers of modern computer science:
"Computer science is about computers in the same way that astronomy is about telescopes."

To put it another way, Computer Science (CS) is to Software Engineering (SE) what Physics is to Civil Engineering. That is, CS is the academic branch of computing that takes care of the theoretical aspects, whereas SE is one of the practical branches that is responsible for actually building things.

As for which is preferable, that depends on what you want to learn. If you're interested in developing software, that's what SE is all about. CS is applicable to software development, but is not primarily concerned with it. CS is what you'd want if you're more interested in, e.g., the mathematical basis of encryption of compression algorithms (as opposed to programs thatuse those algorithms).

Hope that helped.

Contact Manager Linked List Help in C and C++

riskyricky — Wed, 15 Oct 2008 12:56:20 -0600

I Have created a Contact manager that stores contacts along with other information. I used a fixed size array, and need help changing program into a linked list. I also need help creating a search function. This function would let the user search the contacts by name, phone, address, etc. How would i get the function to search each list.

My program code is:

CODE

/* In this program we create a contact manager to manage three total
contacts, by student ID. Includes phone number GPA and Hours.*/

#include <stdio.h>

enum kind {GPA, HOURS} kind;

struct student{

        union grade {
                            int hours;
                                    double gpa;} grade;
                int kind;
        int id;

        struct phone{

            int area;
                        int pre;
                        int suf;} phone;
        };

int main (int argc, char **argv){

    int entry, i;
    struct student stu[3];

    char gh;

    int num = 0;

do{

    printf("[1] Enter a new Contact \n");
    printf("[2] Display the Contacts \n");
    printf("[3] Quit\n\n");
    printf("Enter 1 - 3: ");
            scanf("%i", &entry);

    switch(entry){

        case 1:
            printf("Enter a Student ID number:\n900");
            scanf("%i", &stu[num].id);
            printf("[G] Enter GPA:\n");
            printf("[H] Enter number of completed Hours\n");
                    scanf(" %c", &gh);
                    switch(gh){
                            case 'G':
                                        stu[num].kind = GPA;
                                                printf("GPA: ");
                                                scanf(" %lf", &stu[num].grade.gpa);
                                    break;
                                case 'H':
                                        stu[num].kind = HOURS;
                                                printf("Hours: ");
                                                scanf(" %i", &stu[num].grade.hours);
                                    break;

                        printf("Enter the phone number (###) ###-####\n");
                        scanf(" (%i) %i-%i", &stu[num].phone.area, &stu[num].phone.pre, &stu[num].phone.suf);

    break;

        case 2:

            if(stu[i].kind == GPA){
                    printf("GPA: %lf\n", stu[i].grade.gpa);

            }
            else if(stu[i].kind == HOURS){
                printf("Hours: %i\n", stu[i].grade.hours);
            }
                printf("Phone: (%i) %i-%i\n", stu[i].phone.area, stu[i].phone.pre, stu[i].phone.suf);
            }

            break;

        case 3:

            printf("Thank You for using MyContactManager\n");

            break;

            default:
                    printf("Entry not acceptable\n");

}

} while(entry < 3);

        return (0);

}

Any help greatly Appreciated. Thanks!

hi all,

now im on the last bit of my tool i have been making i have come across a error when i move my file to a new dir and then want to convert the file it wont let me its like vb.net is still using it and wont do anything with it unless i close the app down and open it again this is the code im using to move/copy my file

CODE

Dim pic As FileInfo

        Try
            pic = New FileInfo(TextBox1.Text)

            If pic.Exists() Then
                pic.CopyTo("C:\mydir\" & RichTextBox1.Text & ".tga")
                MsgBox("Moved Successfully! ") 'add this in testing to make sure its working

            Else
                MsgBox("ERROR in Moving File")
            End If
        Finally

        End Try

i have also used

getting ruby to read characters seperatly in Ruby

Inkman — Wed, 15 Oct 2008 12:51:05 -0600

I know this tread is kinda old, but I will post anyway.

K, I think this will work for my roman numeral program, I'm a noobie at this stuff, So I don't fully grasp what it is you said. What am I sposed to do to this code without it crashing? I already took the liberty of making a roman numeral version of this. Also, how do you get rid of the spaces you were talking about tacking on? This one won't need them.

This is for old roman numeral, where you add starting at the biggest number, whether that makes a difference or not. so 9 would be VIIII, and 36 would be XXXVI

CODE

puts 'Place a number for its roman numeral.'
roman={'I'=>1, 'V'=>5, 'X'=>10, 'L'=>50, 'C'=>100, 'D'=>500, 'M'=>1000} .to_s
num=gets.chomp

num.split(//).each { |char| print roman[char].to_s + " " }
puts 'Place a number for its roman numeral.' roman={'I'=>1, 'V'=>5, 'X'=>10, 'L'=>50, 'C'=>100, 'D'=>500, 'M'=>1000}.to_s input=gets.chomp

I also tried

CODE

puts 'Place a number for its roman numeral.'
roman={'I'=>1, 'V'=>5, 'X'=>10, 'L'=>50, 'C'=>100, 'D'=>500, 'M'=>1000} .to_s
num=gets.chomp

num.split(//).each { |char| print roman[char].to_s + " " }

I removed the very last line, it didn't crash, but all it did was repeat back my inputs.

I almost forgot, here is my first attempt at it, it does one exact number at a time like 1000 for M, 10 for X and so forth. I had same problem, it won't take all my input and put in all the numerals. Anyway, here is my failure

CODE

roman = gets.chomp.to_i

if roman == 1
  puts 'I'
    elsif roman == 5
      puts 'V'
        elsif roman == 10
          puts 'X'
            elsif roman == 50
              puts 'L'
                elsif roman == 100
                  puts 'C'
                    elsif roman == 500
                      puts 'D'
                        elsif roman == 1000
                          puts 'M'


puts roman.to_i
end

How to use an array to populate a selection list? in PHP

jakev383 — Wed, 15 Oct 2008 12:50:13 -0600

I have an array that is dynamic; the values can change, as well as the number of elements in the array.
the array (as a static example) is this:
option[1]=one
option[2]=two
option[3]=three

and so on; could be 3 elements, could be 50.
How would I create a selection list (drop down box) using the values of the array, selectable by the user? I'm trying to create a form and want the user to be able to select the drop down menu item. I'm getting the array from a while loop, reading a text file (one element per line) into the array.
Thanks for any tips!

How to determine numerical values of a character in C and C++

oxyron — Wed, 15 Oct 2008 12:49:38 -0600

How do you write a code that determines the numerical value of a char containing a digit in the range '0' ... '9' to an integer with the appropriate value? Like as an example, if ch has the value '3', the value 3 will be assigned to an int variable.

I know this is probably simple, but I am very new to C++.

Can OpenDarwin Run Mac Apps? in Computer Support & Operating Systems

GWatt — Wed, 15 Oct 2008 12:39:26 -0600

I believe that OpenDarwin (now PureDarwin) can run Mac OS X executable files since they are both based off the xnu/mach kernel.
XNU = X is not Unix /confused.gif" style="vertical-align:middle" emoid=":/" border="0" alt="confused.gif" />

However, to run GUI apps you would need a compatibility layer to masquerade as Cocoa/Carbon. GNUStep provides a similar class library to Coca, except that the GNU classes don't have "NS" in front of everything.

You might be able to compile sources intended for Mac with some tweaking.

When are Switch statements appropriate in C and C++

INTERROBANG!? — Wed, 15 Oct 2008 12:36:27 -0600

So i have a question...

i was searching around the forum and after looking at some advice people were giving started to wonder "When is a switch statement appropriate to use"(as opposed to a loop with a if statement to check for bad user input).

the only case i can think of is a somewhat complicated menu or such in which the choices can not be easily organized into a array or some other data type.

let me know what you guys think.
