[Dev-C++] searching characters in a string newbie

[Patel, N. M <Nil...@qu...>]

This maybe a easy one. But I have a string containing '|'.
I need to write a little code where it search for '|' and returns
whatever string is between the first '|' and the 2nd '|'.=20

Myabe this might be more clear.

cat|dog|mouse|house.

the cat, dog, mouse and house and not predefined.

so i need a way where i can search for '|' and another '|' and return dog.=
=20

i tried doing a method using find_first_of method, but did not turn out =
correctly.=20

any suggestions=3F

Subject: [Dev-C++] Priority Defualt

Hi, I want to know how to set the default priority of a C++ program to=20
realtime (in windows).
If you know how to do this, or want me to be more specific, please reply.

Cheers
~ Roo

I assume you mean how to have the program set it's own priority to the=20
real time class.

The following is a snippet from some code I wrote.

# define WIN32_LEAN_AND_MEAN 1
# include <windows.h>*

...
*
  if(SetPriorityClass( GetCurrentProcess(), IDLE_PRIORITY_CLASS) =3D=3D 0)
  {
    cout << "\nError setting priority for process id #" <<=20
GetCurrentProcessId() << endl;
    cout << "Error # =3D " << GetLastError() << endl;
  }

Look for the documentation for the constant for the real-time class. If=20
you want the rest of the stuff in windows.h then you can remove the lean=20
and mean define.

strchr

The latest survey displays that it requires an average of just 3.8
drinkings to effect a katzenjammer. But this tablets
supports you elude hang-overs and wake up feeling immense from head

Use string::find() to find both the first, and the second "|", then use=20
string::substr() to get what's in between.
