Programming :: Out Of Range Vector Iterator?

Mar 20, 2011

I'm not really a C++ noob at all, but I am a little rusty at the moment. Still, I CANNOT figure out what is wrong with the following code. I'm using Visual Studio 2010.

Code: #include <iostream>
#include <fstream>
#include <vector>
#include <string>


I THINK I got all of the pertinent code. Anyway, it fails at the *** line. I CANNOT figure out why. If I modify it to be linein.size()-30, it STILL gives me an error. That makes zero sense.

Programming :: Python: Get The Return Value Of The Last Function?

Jun 13, 2010

But it's been hell finding an answer, or I just don't know what to look for..I have a prompt that asks for a float, and if the user doesn't put in a valid number, then it should die with an error message.

def die_with_error():
print 'ERROR: You didn't specify a valid number!'

Programming :: Pointer As Function Return Doubt?

Jul 15, 2010

I'm getting some information about C language and this session of a C book (follow the above link) is using a bad example for me. When I'm trying this example of function returning a pointer, my compiler is stating a warning that I return a pointer to a local variable. I realized that it is error prone after all this variable may be override before the function has done his execution. And the author is fooling me saying that this example is "perfectly safe". I'm wrong? There is something that I don't got yet? Sorry but this site is preventing me to post the link of book cause I'm a newbie, so a need the hack it. Just strip out the question signs:

Programming :: Python - Only Return Information For A Particular Function When A Flag Is Passed

Oct 28, 2010

I have a script that i want to add some functionality to, but im new to python. Right now it runs command line as ./script https://server user passwd verbose , which returns alot of informtion. I would like it to be able to only return information for a particular function when a flag is passed. exp: ./script https://server user passwd verbose -m (for memory only)

Under the ClassesToCheck section are the different things that can be retrieved. I would like that when you run the script as ./script https://server user passwd verbose -m, it returns only the 'Memory' info. -c would be for 'CPU', etc... Also, i would like the OK at the end of the script to be the first line that is return in the output instead of the last.

Programming :: How To Write UI-independent Code

Jan 11, 2011

How do you write a program that is independent of the UI (the functionality is a library, and you have, for example, CLI and GUI interfaces as separate apps). The problem I have is how to report status and prompt the user from within UI-independent code? I could split it into parts that do not require any user interaction, but then most of the functionality will be in the UI, not the backend.

General :: Write Script To Use Function And Still Keep Function Active?

Feb 21, 2010

the function terminates if no key is pressed for 10 consecutive seconds. I tried using the -t option as suggested in some forums, but my version of showkey doesn't have the option of changing the timeout. The options I get are:

-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).

Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?
