newbie questions - please help me get started

by Darrell Cormier

I hope this is not a totally ignorant/stupid question, but please help me get started. I am fairly new to C++, brand new to C++ in *nix, and brand new to kdevelop. I am trying to get started with a file that a friend gave me and am unable to compile it. Hear is the #include section of the file: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <ctype.h> #include <time.h> #include <alloc.h> #include <io.h> #include <sys/types.h> #include <sys/stat.h> #include <math.h> #include <sys/utsname.h> #include <search.h> #include <memory.h> #include <dir.h> #include <dos.h> #include "ri40file.hpp" and here are the compiler ouput messages that I am getting: *cd "/home/big_bear/rid_dev/cpp/wmc/ptcdump/debug/src" && WANT_AUTOCONF_2_5="1" WANT_AUTOMAKE_1_6="1" gmake -k ptcdump.lo *if /bin/sh ../libtool --mode=compile g++ -DHAVE_CONFIG_H -I. -I/home/big_bear/rid_dev/cpp/wmc/ptcdump/src -I.. -O0 -g3 -MT ptcdump.lo -MD -MP -MF ".deps/ptcdump.Tpo" -c -o ptcdump.lo `test -f '/home/big_bear/rid_dev/cpp/wmc/ptcdump/src/ptcdump.cpp' || echo '/home/big_bear/rid_dev/cpp/wmc/ptcdump/src/'`/home/big_bear/rid_dev/cpp/wmc/ptcdump/src/ptcdump.cpp; then mv -f ".deps/ptcdump.Tpo" ".deps/ptcdump.Plo"; else rm -f ".deps/ptcdump.Tpo"; exit 1; fi *g++ -DHAVE_CONFIG_H -I. -I/home/big_bear/rid_dev/cpp/wmc/ptcdump/src -I.. -O0 -g3 -MT ptcdump.lo -MD -MP -MF .deps/ptcdump.Tpo -c /home/big_bear/rid_dev/cpp/wmc/ptcdump/src/ptcdump.cpp -fPIC *In file included from /usr/include/g++/backward/alloc.h:46, *from /home/big_bear/rid_dev/cpp/wmc/ptcdump/src/ptcdump.cpp:20: */usr/include/g++/backward/backward_warning.h:32:2: warning: #warning This file includes at least one deprecated or antiquated header.

RE: [suse-programming-e] FSM example

by ntienjem＠netscape.net

Quick Introduction to Finite State Machines (FSM) or Finite State Automata (FSA) 1.1 Informal Definition An FSA consists of - a finite set of states, - a set of transitions from state to state; a transition occurs on an input symbol chosen from an alphabet. - an initial state, that is the state in which the FSA starts; it is an element of the set of states. - a set of final (accepting) states; that is a subset of the set of states. - an Alphabet, that is a set of input symbols. Example 1 An FSA which accepts all even numbers. The alphabet is the digits 0,1,2,3,4,5,6,7,8,9. The set of states is {a,b,c}. The initial state is a. The set of final states is {b}. The set of transitions is as follows: = in state a with input 0 or 2 or 4 or 6 or 8 go to state b. = in state a with input 1 or 3 or 5 or 7 or 9 go to state c. = in state c with input 0 or 2 or 4 or 6 or 8 go to state b. = in state c with input 1 or 3 or 5 or 7 or 9 go to state c. = in state b with input 0 or 2 or 4 or 6 or 8 go to state b. = in state b with input 1 or 3 or 5 or 7 or 9 go to state c. 1.2 Formal Definition An FSA is a 5-tuple (S, V, h, s0, F) where - S is the finite set of states, - h is an application which maps SxV to S; that is for each s in S and v in V it holds h(s,v) = s' where s' is in S. - s0 is the initial state; it is an element of the set of states S. - F is the set of final (accepting) states; that is a subset of the set of states S. - V is the Alphabet, that is a set of input symbols. Example 2 Please, reconsider example 1. Since we will be considering the behavior of an FSA on a string of symbols of an alphabet, we have to extend the application h to apply to a state and a string. Let W denote the set of all strings formed using an alphabet. Then, h is an application which maps SxW to S; that is for each s in S and w = w'v in W it holds h(s,w'v) = h(h(s,w'),v), where w' is in W. Example 3 Based on example 2, h(a, 1234) = h( h(a, 123), 4) = ... = h( h( h( h(a, 1), 2), 3), 4) = b. Example 4 a) Consider an FSA which recognizes numbers, e.g. 123, +1234.56E23, -231.45e-05, 432.89. b) Consider an FSA which recognizes all positive integer numbers which are multiple of 3. Definition 1.2 may easily be translated into a C++ program. 1.3 Deterministic FSA An FSA (S, V, h, s0, F) is deterministic (DFSA for short) if for each s in S and each v in V it holds that the number of states resulting from h(s,v) is at most 1; otherwise (S, V, h, s0, F) is nondeterministic (NFSA for short). I hope, I have kept it simple and short. Good Luck!

Jumping from one input text to the next input text automatically

by Prabu Subroto

Dear my friends.... I am writing a web program with Mozilla (as the only one client) and Java Script for Mozilla (developer.netscape.com). I want if the user type the date (tanggal) after 2 character than the cursor will jump to the next input text automatically. I used "tanggal.focus()" but no expected result comes. Anybody would be so nice to tell me the solution? Thank you so much. ps. Here is my listing program below. ======= <html> <head> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <script language="JavaScript"> function cek(fieldnya){ var namavar = fieldnya.name; var nilaivar = fieldnya.value; var panjangnya = nilaivar.length; if (namavar=='tanggal'){ if (nilaivar<1 || nilaivar>31){ alert("Ungültiges Datum"); } if (panjangnya>2){ alert("Datum hat nur 2 Zahlen"); } } if (namavar=='bulan'){ if (nilaivar<1 || nilaivar>12){ alert("Ungültiges Monat"); } if (panjangnya>2){ alert("Monat hat nur 2 Zahlen"); } } if (namavar=='tahun'){ if (nilaivar<0){ alert("Ungültiges Jahre"); } if (panjangnya>4){ alert("Jahre hat nur 4 Zahlen"); } } } function pindahsorot(pindah){ var namavarpindah = pindah.name; var nilaivarpindah = pindah.value; var panjangnyapindah = nilaivarpindah.length; //alert("Panjangnya udah : "+panjangnyapindah+" namavarpindah : "+namavarpindah+ //" nilaivarpindah : "+nilaivarpindah); if (namavarpindah=='tanggal'){ if (panjangnyapindah>=2){ //alert("pindah akh"); this.form.bulan.select(); this.form.bulan.focus(); } } } </script> <body> <form name="customer"> 14.

C# for Linux. Probably worth consideration.

by Steven T. Hatton

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I thought about posting this to SLE just for the fun of watching the hysteria unfold, but I would rather not see the list completely melt down. I haven't looked closely at C#, but I have learned a bit of relevant information about it. It is not owned by Microsoft, and it is a formal open standard. I suspect Microsoft bought some very good ideas to put into C++. They also have, at least one or two people there with solid programming experience, and the ability to apply it. The language was designed on the basis of a lot of history, and most likely a lot of research into what works and what doesn't. Microsoft put a lot of effort into C#, and would like to see it catch on. I say the language is worth reviewing as a potential mainstream GNU/Linux development tool. Give if it really does improve the quality and pace of production, then we give MS what the wanted. Buy-in. And we give them all the buy-in they can handle, and then some. If it really does suck, hey, reviewing a language is always an learning opportunity. To ignore it because MS sponsored it, would be like ignoring the technological advancements of another (hostile) country because you don't get along with them. In terms of statesmanship, and history, that is what is typically know as really stupid.

by Filippos Papadopoulos

Hi. I have some trouble with rpmlib. I see that in the Maximum-RPM book (a bit old), there are referenced some functions like rpmReadPackageInfo e.t.c. The problem is that i dont find any definition of this function and some others, inside /usr/include/rpm/*.h Can you help me here? Thanks.
