kandi X-RAY | StringStream Summary

StringStream is a PHP library. StringStream has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Stream wrapper for strings. Basically, like php://temp ~~except that you can have multiple streams at once, and can pre-initialise the contents~~. This was never tested by my past self, php://temp is in fact not shared between handles and this package was never needed. Just use php://temp.

extract line of text into a variable string

Asked 2022-Apr-10 at 21:52

I'm building a code that must search for a line of text in a string variable that contains many lines of text (example the text variable has lines formed like this MILAN;F205).

Once the user has entered the city he wants to search for, the program must search the database for the city entered by the user (in this case Milan) and extract only that line so in this case it extracts MILAN;F205 and puts it in the variable result.

You could:

read your input stream into a vector of lines, and
walk that vector of lines checking if it starts with a given city name;
copying those lines that do match to an output vector (or just printing them out, or whatever).

The example below:

uses a std::istringstream instead of a std::fstream as input, and
takes the walk of the input lines and the creation of the output vector to a filter_by_city function.

C++ OpenSSL hash of the file is not the right one

Asked 2022-Apr-05 at 14:28

I want to calculate Sha1 of any given file in C++ using OpenSSL library.

I have read any article on the internet (including all from stackoverflow too) about doing this for almost 3 days.

Finally I get my program to work but the generated hash of any given file is not as it should be.

My code is someway similar to these found here and here but more easy to read and to use further in my program I write.

Also, I want to use C++ code not C code as they are written in the links above, second, they use:

You're missing the finishing calculation on your EVP API attempt. The use of an intermediate string is unnecessary as well. Finally, the function should return the digest as a vector of bytes. let the caller do with that what they want.

Examples using both the EVP API and a BIO chain are shown below.

QUESTION

C++ what is the best sorting container and approach for large datasets (millions of lines)

Asked 2022-Mar-08 at 11:24

I'm tackling a exercise which is supposed to exactly benchmark the time complexity of such code.

The data I'm handling is made up of pairs of strings like this hbFvMF,PZLmRb, each string is present two times in the dataset, once on position 1 and once on position 2 . so the first string would point to zvEcqe,hbFvMF for example and the list goes on....

example dataset of 50k pairs

I've been able to produce code which doesn't have much problem sorting these datasets up to 50k pairs, where it takes about 4-5 minutes. 10k gets sorted in a matter of seconds.

The problem is that my code is supposed to handle datasets of up to 5 million pairs. So I'm trying to see what more I can do. I will post my two best attempts, initial one with vectors, which I thought I could upgrade by replacing vector with unsorted_map because of the better time complexity when searching, but to my surprise, there was almost no difference between the two containers when I tested it. I'm not sure if my approach to the problem or the containers I'm choosing are causing the steep sorting times...

Attempt with vectors:

You can use a trie data structure, here's a paper that explains an algorithm to do that: https://people.eng.unimelb.edu.au/jzobel/fulltext/acsc03sz.pdf

But you have to implement the trie from scratch because as far as I know there is no default trie implementation in c++.

I'd argue that stringstream is not "modern C++"¹. (I'll also admit we don't have something as a good replacement for scanf; we do have std::format that is very nice, and replaces std::cout << shenanigans with a syntax reminescent of Python's format strings, and is much faster. Sadly, it hasn't hit standard libraries yet.)

I'll actually say that I think your sscanf code is cleaner, and saner than the stringstream code: sscanf leaves things in an easier-to-understand state when parsing the line fails.

There's libraries you can use to build a line parser; Boost::spirit::qi is probably the most well-known. You can do things like

Vector subscript out of range AND The application was unable to start correctly [c++]

Asked 2022-Feb-17 at 18:24

I'm writing quite simple program in c++ using Visual Studio but i keep getting 2 errors and i could use some help.
One sometimes pops up when i run Local Windows Debugger after the app crashed and it says:
The application was unable to start correctly (0xc0000142)

message sometimes when running

And the second one i guess happens between after cin >> kwota;. Don't really know when though, because VS is not showing any exception. It's just a message box from the os. It says:

Boost Serialization, need help understanding

Asked 2022-Feb-13 at 16:00

I've attached the boost sample serialization code below. I see that they create an output archive and then write the class to the output archive. Then later, they create an input archive and read from the input archive into a new class instance. My question is, how does the input archive know which output archive its reading data from? For example, say I have multiple output archives. How does the input archive that is created know which output archive to read from? I'm not understanding how this is working. Thanks for your help!

Like others said, you can set up a stream from existing content. That can be from memory (say istringstream) or from a file (say ifstream).

All that matters is what content you stream from. Here's you first example modified to save 10 different streams, which can be read back in any order, or not at all:
