A map associates a value to be stored with a key as an identifier. You use the key to access the
stored value. Hence a dictionary is a map of words (key) and descriptions (value).

clock_t clock(void); It returns the processor time that the program has
spent so far from the beginning of its execution.

 clock()/CLOCKS_PER_SEC is that time in seconds (integer).

#include <iostream>
#include <ctime>

void useless()
{
  for(int i=0; i<1024*1024*1024; i++)
     ;

Hi Ioannis,

> useful stuff in there.
 Good idea....if I could understand how to use it. The original function  
has been given to us by our teacher as a help...it's for three weeks now  
that I am in contact with C++. This routine should return a time (no  
matter which, but in seconds would be great), so I can measure the time  
passed from start to end of the task given to the user. Is there a  
portable solution or does the original function only work with gcc  
greater than 2.95.3 (perhaps gcc 3.x)?
In the code I use MyTime as follows:

----------------------------8< schnipp------------------------------
start=3DMyTime();
[task]
end=3DMyTime();
complete=3D(end - start) + (10 * penaltycounter);
----------------------------schnapp >8------------------------------

You understand what I want? ;)

 As I stated: Under Linux it does compile, and time.h is included, so  
this should be no problem. Below a list of all included header files.

#include <iostream>
using std::cout; using std::cin;
#include <cstdlib>
using std::rand; using std::srand;
#include <sys/time.h>
#include <cmath>

For portable code use the functions provided in time.h . There is much
useful stuff in there.

I believe you need tin #include <sys/time.h>

Hello,

In university I am doing a programming course and last week we had an  
excercise using a given function to measure time:

----------------------------8< schnipp------------------------------
double MyTime() {
  struct timeval Tp;
  gettimeofday (&Tp, NULL);
  return Tp.tv_sec + (Tp.tv_usec /10000000.);
}
----------------------------schnapp >8------------------------------

At home I wanted to finish the program using Dev-C++ (current beta with  
fixed exe), but the compiler refused work when compiling this function  
with the message

----------------------------8< schnipp------------------------------
aggregate `struct timeval Tp' has incomplete type and cannot be  
initialized
----------------------------schnapp >8------------------------------

But in university (under Linux) it does work....so is this a problem of  
the compiler (gcc versions differ in university and at home) or a  
platform problem (Linux specific parts)? Sorry, I am no expert, just had  
two weeks of this course and I am only used to basic (under DOS).

Reading and writing to a file is an important and common task. So I will try
to explain the steps required. (As an aside I would do all of this in a
wrapper class - other here may disagree with that because it will have over
heads but it creates a much easer interface)

To open a file:
===============

I will just look at creating a text file. This makes it easier to test that
you have written to the file correctly because you can open it up using
notepad and check that the format is what you desired.

First you need to have a variable to the file stream. I will create a file
which can be used to read the file as well as write to it. It can be
declared as follows:

fstream iofile;

Next the iofile variable needs to be associated with a file this can be done
by using the open method of the fstream class as follows:

iofile.open("MyFileName.txt");

Obviously you can use any name in the quotes, and any extension you like.

Now did the file open work correctly? If it did then iofile will be a
non-zero value so teh following test can check this:

if (!(iofile))
   cerr << "File " << "MyFileName.txt" << " couldn't be opened, sorry...\n";

Writing to the file:
====================

First you need to write to the file the following code will write out a line
to the file, in this case it will write the contents of the variable called
line to the file followed by a new line. (The variable line was declared as
a string object, but it should manage any data type that has to output
operator << defined)

iofile << line << "\n";

Reading from the file
=====================

There are many ways to do this, my preferred approach is to read the data in
a line at a time and then extract the information from that line however you
may want to adopt a different approach maybe by using the input operator >>.
However to read a whole line in:

   char data [1024];
   // read in the next line and store it in details of cObject
   iofile.getline(data,1024);
   string result (data);
   return result;

This code creates a temporary variable called data that is a character array
and will have more space than I need to read in a single line. The data is
then read into this variable using the getline method of the fstream class.
I then copy it to string object called result. This code is part of a
function and I return result where it can then be parsed and the data
extracted. For your application you don't need data to be anywhere near as
large as 1024 chars, and as I said you may want to experiment with the input
operator <<

Position in the file
====================
The file has two "positions" in the file one is related to the writing and
the other is related to the reading. These can be set using the following
functions

iofile.seekg(0) // sets the read (or get) position to the start of the file
iofile.seekp(0) // set the write (or put) position to the start of the file

Buffers
=======

If you are working in mixed mode i.e. read write and then read some more you
will be well advised to flush the buffers to ensure that your data is
actually written to the file rather than sitting on the buffer:

iofile.flush();

Clear the File
==============

There are several ways to empty a file one simple approach is to close the
file and then open it but truncate the file to length zero. This is done as
follows:

   // Close the file and then reopen it but truncate to zero
   iofile.close();
   iofile.open("MyFileName.txt",
ios_base::in|ios_base::out|ios_base::trunc);

This is slightly different from the previous open method, because now it has
a second parameter. This second parameter using flags to tell the program
how it should treat the file. The flags are in the namespace called ios_base
and the three flags used are in (for input - read), out (yeap output -
write) and trunc (truncate to zero)

hope this helps.

Graeme.

Ah, finally somebody asks!
Here's my list of arguments:
1) You're only sending an email here. Markups are completely redundant.
All this HTML only waste space and bandwidth.

2) HTML mail with hardcoded fontnames look horrible in my Linux
emailclient.

3) HTML mail can contain script viruses.

4) HTML mail mess up the archives. When you try to see a message in the
archive, you see all the HTML code instead of the email!

If setting up an icon for your program is what you need: Dev-C++ beta 3
will do this automatically for you.

There may be some information on the MSDN site
(http://msdn.microsoft.com) regarding resource scripts.

Okay, I'll bite. Why are they evil?

Please... no HTML mail! They're evil.

There is only one small problem. If you are trying to write portable =
code, <conio_mingw.h> is not universal.

Hi all,

I'm an experienced Unix C/C++ programmer. A while ago I tried my first steps
on the Windows programming ice, and although I've slipped a few times, I'm
slowly getting my head around it. I've managed to conjure up some windows,
get event handling going, etc.

I've chosen Dev C++ as my development tool, and despite some interesting
comments I read in previous messages, I'm pretty happy with it. (Hey, the

Anyway, I was wondering if anyone could point me in the direction of a good
tutorial for the Resource Editor, provided with Dev C++. I've searched far
and wide, but I can't seem to get any useful information regarding setting
up a rsrc.rc file.

If anyone could help me, it would be most appreciated.

Thanks in advance,

A map is a template class in the STL (standard template library). Look 
into STL documentation.

I think if you include ostream.h and create an object of the ostream class, 
then use the .open command you should be ok.

ofstream ofstreamObject;   // For managing the text file
ofstreamObject.open( "File1.txt"); // Create and name our text file
ofstreamObject.close();

No, in case of failure new throws by default an std::bad_alloc exception
defined in <new>. It doesn't return 0.

Yes, you can access the rest of memory as "free store". Stack is used to
store the execution path of a program and local objects.

Example. Imagine that you have the code:

void k()
{
 int x=1;
 f();
 int y=g(x);
 f();
}

int main()
{
 int a=5;
 f();
 int r=g(a);
 k();
}


In the stack the following is stored:

a=5;
pointer to f() call. -> // f() things executed here. When it finishes: |
<-----------------------------------------------------------------------
-------
int r;
pointer to g() call--> // g() things executed here. When it finishes: |
<-----------------------------------------------------------------------
--------
r=some_value
pointer to k() call --> 
                              int x=1;
                              pointer to f() call ---> //finishes |
                              <-------------------------------------
                              int y;
                              pointer to g() call---> // finishes|
                              <--------------------------------------
                              y=some_value
                              pointer to f() call ---> //finishes |
                              <-------------------------------------
                              k() finishes. Automatic local objects in
the stack die |
<-----------------------------------------------------------------------
----------------

main() ends. 
Automatic local objects in the stack die
return success indicator


I hope it gives some idea.

Well, I'll hold my horses a bit longer before I cry wolf, wolf the next
time.:o)

As Ioannis has pointed out the different results are differences in the
implementation of the mingw32 compiler. Evolving from allowing ca 31MB stack
space to ca 2MB. Probably to prevent us from cheating?

The following code shows that you have access to all the memory your OS will
give you *S*.

I was looking to some pages regarding Kernighan, Ritchie, Thompson, Unix
& stuff and i came across some interesting link of a guy that was
working at Bell Labos those times (great mind) with info i think is
interesting. It is not C or C++ but i think it is useful. :)

hi, here is my program that is supposed to do the following:

Enter a series of records from the keyboard, each record consisting of a 
two-word name and an integer,
example MEG RAM 23, as one entry
The program will keep a count of the number of entries. After the last one 
is entered, enter a "sentinel" code, some string that will indicate that the 
data has been completely entered.
Then the data will be saved to a file in the format of
#data  name  #  name  #.......
Then the data will be read from the file and displayed on the screen, one 
entry per line.

#include "apstring.h"
#include <iostream.h>
#include <fstream.h>
#include <conio.h>

int main()
{
   apstring name1, name2, x, check;
   ifstream infile;
   infile.open("stuff.dat");
   int n;
   cin.ignore(80,'\n');
   getline(cin,x);
   check = "end";
   while(x!=check)
   {
      infile >> name1 >> name2 >> n >> "\n";
      cin.ignore(80,'\n');
      getline(cin, x);
   }
   infile.close();
   getch();

   ofstream xfile;
   xfile.open("stuff.dat");
   getch();
   xfile.close();
}

I don't know how to do the ofstream part, and I don't know whether I 
actually saved the data in a file, and how to access the file and display 
it? Would you please tell me how to do that, thank you!
