Hi:
I am new user of Dev C++. I am using the latest beta version Dev C++ 5.0.
From the download page screen shot  it seems one can create subfolders in a project. I want to know how can I add directories to the project like in JBuilder IDE for Java. Any help in this regard is appreciated.
Thanks

Hello!

Don't use atof() for converting from text string to a double.

Use strtod() instead, since it will inform you how many characters it
consumed.

char mystring[] =3D "1.2E-3*3";
char *p =3D mystring;
char *end;
num =3D strtod(p,&end);

Now end will point to the '*' character, since '1.2E-3' is consumed and
returned as the double 0.0012.

Note also when parsing infix expressions, that you normally have to take
care of unary signs, i.e. 1+-2 which should be evaluated as 1 + (-2).

Easiest is to perform the parsing with a recursive-descent parser, i.e.
something like:

eval_expr()
  return eval_additive()

eval_additive()
  while (*p =3D=3D '+' || *p =3D=3D '-')
    if (*p =3D=3D '+') {
      p++;
      n +=3D eval_multiplicative()
    } else {
      p++;
      n -=3D eval_multiplicative()
    }
  return n;

eval_multiplicative()
  n =3D eval_factor()
  while (*p =3D=3D '*' || *p =3D=3D '/')
    if (*p =3D=3D '*') {
      p++;
      n *=3D eval_factor();
    } else {
      p++;
      n /=3D eval_factor();
    }
  return n;

eval_factor()
  if (*p =3D=3D =B4+') {p++; return eval_factor(); }
  if (*p =3D=3D '-') {p++; return -eval_factor(); }
  if (*p =3D=3D '(') {p++; n =3D eval_expr(); if (p !=3D ')') error(); retu=
rn n; }
  return number();

Good luck!

Thanks.  However I see tutorials on creating a DLL there, though none 
on specifically creating one within Dev-C++.  I have been able to 
create one, but need to drop to a command prompt to run the final steps 
(using Dev-C++ to only create the object file).  Dev-C++ errors out 
with porblems related to the path.

Has anyone written a tutorial, from start to finish, of using Dev-C++ 
and the .dll template to build a simple DLL?  I can build a DLL, but 
not fully within Dev-C++.

Thanks,

Duncan

You could use a pointer, which defaults to the base element of an array when 
pointed to it, and then use ++ to go to the next element. This will of 
course not work with multi-byte characters or unicode characters.

It's a bit hard to help if you don't include the failing code in your
mail...

i need to convert the chars in an array into float and put them onto a stack... i used atof but i can't change the address of the elements of the array so i always put the same value into the stack... can anyone help??

kind regards...

It is:

MyClass* Array_or_variable_name = new MyClass;

or MyClass* Array_name = new MyClass[some_number];

I noticed some unusual embedded characters in CVS in
some of the filenames. These are all in the folder:
/dev-cpp/V5/source/images/blue

Here's an example:
/dev-cpp/V5/source/images/blue/Arrange%2520Icons.bmp 

Maybe this isn't noticable when using WinCVS, but I
wrote my own program to download source form the CVS
browser at SourceForge, and this became a problem for
me until I figured it out.

If you want to see how this works, you can see this
bitmap by entering this URL in a browser (of course it
has to be on one line):

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/dev-cpp/V5/source/images/blue/Arrange%2520Icons.bmp?rev=HEAD&content-type=text/plain
