The Karnaugh map (KM or K-map) is a method of simplifying Boolean algebra expressions. Maurice Karnaugh introduced it in 1953 as a refinement of Edward Veitch's 1952 Veitch chart, which actually was a rediscovery of Allan Marquand's 1881 logical diagram aka Marquand diagram but with a focus now set on its utility for switching circuits. Veitch charts are therefore also known as Marquand. These icons are used to highlight improvement needs and plan kaizen workshops at specific processes that are critical to achieving the Future State Map of the value stream. This icon is a tool to batch kanbans in order to level the production volume and mix over a period of time This is an inventory “supermarket” (kanban stockpoint).
I possess a
chart
namedvalueMap
as comes after:Then I feel moving this chart to a functionality by reference point:
How can I get the value from the map, which is definitely approved as a benchmark to a functionality?

Sadly
std::map::operator
is a non-const member functionality, and you have got a const benchmark.You either require to alter the trademark of
function
or do:agent
deals with the mistake by incorporating a default-constructed value to the chart and returning a guide to it. This can be no use when all you have got is definitely a const guide, so you will need to do something different.Youcouldignore the likelihood and create
Steve JessopSteve Jessopchain value = chart.find('thread')-gt;second;
, if your program logic somehow guarantees that'line'
can be already a essential. The apparent problem will be that if you're wrong then you get undefined actions.237k2828 yellow metal badges380380 metallic badges636636 bronze badges
map.at('key') punches exception if lacking key
If e does not really suit the essential of any component in the box, the function includes an outofrange exception.

The reply bySteve Jessopexplains well, why you can't make use of
std::chart::operator
on aconst std::map
.Gabe Rainbow'sanswer suggests a good substitute. I'd simply including to offer some instance code on how to make use ofmap::at
. Therefore, here can be an improved example of yourfunctionality
:And right here is certainly an illustration
primary
function:Result:
Value of key 'thread': abc

How can I obtain the value from the chart, which will be exceeded as a reference to a function?
Well, you can pass it as a benchmark. The standard reference wrapper that is definitely.
And the check.
I think this can be great and basic. Enjoy.
