dev-cpp-users Mailing List for Dev-C++ (Page 23)

Does this problem need the "C++ feature" to solve or could just be done with
C or C/C++ hybrid?
it seem to me you omly need C or C/C++ hybrid, and classes would only
confuse the issue.

Hello there.

I doubt that anyone on this list is going to write the program and send it to you... That would completely defeat the point of a "school assignment". However, I'll be glad to give you some pointers in the right direction so that you can then try to write the program based on that information.

Let us assume that the number of possible characters is 128. If you think of a character in the string as a number (which is what it really is), a number from 0 to 127, an easy approach would be to create an array of ints to hold the number of times that the particular symbol has so far occured.

To give a quick example...

int my_array[128];
for int i=0; i<strlen(my_string); i++)
my_array[my_string[i]]+=1;

Then after you've looped through the entire string and incremented the corresponding array entry for each character that appears in the string, you can simply loop through it again and print out the results. Of course, you don't want to print out the ones that are 0.

Hope this clears things up a bit. If not, feel free to ask again and I will try to explain it further.

Regards
Philip Bennefall

  A string is any combination of

  Write a C++  program to calculate and print the number of different 
  symbols used in a given string. A blank space counts as one symbol.





  Input: Any string. The length is limited to 60 characters. For 
  example:





  Enter a string: Mississipi





  Test data:
  #1. “Say good bye!”
  #2. “The world is 
  round”





  Output: The number of different symbols. For example, the output for the 
  string “Mississipi” is 





  Number of symbols for the string “Mississippi” is: 4

It would be a logical thing to do, if I had in fact received a valid window handle but the window just wasn't showing. Calling ShowWindow with a NULL handle, which is the case right now, wouldn't do much good.

          Dear list,

          I'm having a very strange problem with a seemingly simple piece of code. I'm simply loading a dialog box from a resource, and building it with CreateDialog. It's finding the resource fine, but for some reason CreateDialog returns NULL. According to Msdn, you can get extended information for this particular function with GetLastError so that's exactly what I did. However, GetLastError returns 0 (success)... And still the window is not being created!

          If anyone has the time to take a look at the scode snippet, I would appreciate it very much!

          Thanks in advance.

          Regards

Hello all!

I need to create a procedure that is a loop for searching files with a
specific extension.

For example, when starting the program, in the main function, it
enters in a loop for searching files with a specific extension. When
finding one, it calls a procedure that read this file and after
collecting its content, the file is deleted.

My problem is, I do not know how to access the directory (actually is
the same where my program is) and search for files with an extension
".inf", for example.

I appreciate any help :)

Thanks in advance,

Ricardo.

Well, Tom qian han, maybe you could tell us more about the error ?
What's the full message ?

Try something like this.
      vector<string> ::iterator tmp = ht->second.begin();
      while(tmp!=ht->second.end()){
	std::cout<<*tmp;
	tmp++;

Hello all,

I am having a little problem that is turning me crazy!!!

Well, I declared a hash table ht, using std::map, with a key of type
string, and content of type a vector of string:
sdt::map<string, vector<string>*> ht;


After inserting values into ht, I want to access the records. So, to
access the data I have the key and I found the its respective  line in
ht. I did the following:

std::map<string, vector<string>* >::iterator temp; //temporary structure
temp = ht.find(id);


Now, I want to access the data that is inside the vector that is the
second element in my hash table. I've been trying many ways to do
this, but without success. One of the ways I tried is the following:

vector<string> data; //vector to store the data from the hash table
data.at(0) = temp->second->at(0);


It returns me an error like:

terminate called after throwing an instance of 'std::out_of_range'
  what():  vector::_M_range_check


Does anybody know what could be the problem here?!

Thanks in advance for any help.

No, Wine was one alternative where a Linux machine could use DLL files.

My example with a Linux program using Windows codecs was another reference
where Windows DLL files are used on a Linux machine. One example is the
XBMP (XBox Media Player):

I think my explanation was not clear.I was not talking about the memory
representation of "1.2.3.4", but how the system will store IP. The
system stores an IP address in 4bytes.(As in IPv4 header). I want to
make the string representation of this 4bytes. Think now I made it
clear.

Thanks,
 Lloyd

Hi,

 I am using C++ STL string. I have an IP address something like 1.2.3.4
So its memory will be 0x01020304. I want to initialise a string with
this memory. How can I do this?



int ip=0x01020304;
string s(<I dont know how to fill this area>);

so that 

s[0]=0x01;
s[1]=0x02;
s[2]=0x03;
s[3]=0x04;

Thanks,
 Lloyd

That is not a string.

A string representation of the IP number should have "1.2.3.4" or in
binary:
0x31
0x2e
0x32
0x2e
0x33
0x2e
0x34
0x00

And then there is Wine.

By the way - there are a couple of media players that are making use of
Windows DLL files just to be able to use Windows codecs.

But in this case, the bit problem is that the post is just a request for
using a dll file, without any motivation why. Because of knowing that a
dll file is the Windows name for the concept while actually intending to
use a *.so dynamic library? Because the dll file contains important
functions to use? Because the dll is supposed to contain important
functions, but the functions already existing for Linux, if we just knew
what the dll does?

It is always hard - often impossible - to help someone who are not ready
to write a lot of information about the what and the why.

Hello,      I'll assume that you know that nealy all functions inside a DLL use Windows API, an that Windows API is not supported in Linux kernel.       Bear in mind that even if you have the source code, and it has known functions... ( e.g.: malloc()... ) in the compiled version, the result.dll, the malloc call is assembled  into the windows-spefic malloc implementation, that calls a function like _mzAlloc (or something like that), that actually performs all the mem allocation tasks.      Obviosly, linux kernel malloc implementation( compiled version) probably will not have the same function name and other aspects ( reside on the same address, uses the same number of args, etc, etc ).      So, assuming you considered the above and  the code that resides in the .DLL is a very simple one, you *can* parse the header, load the symbol table, resolve it, load it to a buffer, witch allows you to execute code, and "jmp" to that location.  It is... very hard work, and even if you can do it, the code in the dll, must be very simple( even function calls inside the parsed come, must be in the same calling covention to execute right... and you'll have to resolve the code address all hiover again).  I would not bother without a very good reason... mind you, even if you pull this off, it'll be a hogger of a code....

Linux doesn't use DLL files.  You will want a .so file instead, or  
cross-compile to a .so file.
