C++ Multimap - Tutorial And Example

C++ Multimap with tutorial and examples on HTML, CSS, JavaScript, XHTML, Java, .Net, PHP, C, C++, Python, JSP, Spring, Bootstrap, jQuery, Interview Questions etc.

In C++, a multimap is similar to a map with the additional concept, where multiple elements possess the same keys. It is also not necessary that the key values and mapped values must be unique. The scenario is different in the case of multimaps. In a multimap, keys are always found in sorted order. This ordered property makes it difficult for competitive programmers to implement multimaps.

Moreover, multi maps are associative containers that are formed by combining key-value and mapped value, which is usually sorted or is in a specific order. Elements in multimap may sometimes have equivalent keys.

A multimap has key values, which are generally used to sort and uniquely identify elements, and the mapped values store the definitions or function related to this key. Some differences in the key and mapped value may exist, which later is grouped forming pairs by combining both.

Some notes on Chapter 31, 32 (standard library, STL) of Stroustrup’s “The C++ Programming Language”.

Emplace

I’d never heard the word emplace before, but it turns out that it isn’t a word made up for c++, but is also a dictionary word, meaning to “put into place or position”.

c++11 defines some emplace functions. Here’s an example for vector

#include <vector> #include <iostream> int main() {…

How to: Duplicate keys in .NET dictionaries?

How to: Duplicate keys in .NET dictionaries?

Duplicate keys in .NET dictionaries?

Are there any dictionary classes in the .NET base class library which allow duplicate keys to be used? The only solution I’ve found is to create, for example, a class like:

Dictionary<string, List<object>>

But this is quite irritating to actually use. In Java, I believe a MultiMap accomplishes this, but cannot find an analog in .NET.

UltraLight Multimap:

Simplicity, it wont fail you or let you down. Apply that to planning, to equipment or to your day. Keeping things as simple as possible achieves so much more.

The UltraLight MultiMap was designed to fill a need by special request. The simplest solution to a problem, but the more we looked at the solution the more uses we could find for it. This is simplicity.

When packed its a 2" x 2" bag with a folded section of our fabric, when unfolded its a 11.5" x 8" or workspace ready for writing/planning/sketching on. We've all seen a rupert break out a tin with models in it and carefully construct a scale model. Sometimes time is genuinely of the essence so key important features are what is required. Draw that onto the Ultralight MultiMap and everyone can visualise the situation.

Draw a map with as much or as little detail as you need in a lot less time. You can use this alongside of an Admin Kit to keep important key facts to hand. In the need of rescue but had to move from your last known location to find shelter for reasons of safety? Leave key details on the MultiMap at the location, how many in your party, injuries or any other information that helps them find you! You can even use it to attract attention to yourself if required.

Leaving your vehicle and heading off into a new area or terrain? Leave the date and time you left, planned route and any stop off with expected ETA on the MultiMap on your drivers seat. Add any further contact details you can to assist. Any park warden or ranger finding the vehicle will know who it belongs too and if you are not back with a given time frame can alert rescue services and family.

Create a packing list, note key details, write your medical allergies or other contact information on and repack until its required. Hundreds of uses and so light you wont know you are carrying it.

Resistant to smudging, hot cut to prevent fraying and can be destroyed without catching fire removing all traces of information. Can be written on in pencil or ideally pen for best visibility.

(Additional Information: In testing we had some given to the local regiment, one of the lads came back from behind a bush grinning. 'I've got another use!'. We wont advertise that use for the MultiMap)
