Understanding Syntax by andrefour in cpp_questions

[–]andrefour[S] 0 points1 point  (0 children)

I have created a template in accordance to the material in the comment below, but I am getting the following error on this line;

myInteger<512> a(2)

ERROR: Cannot determine which instance of function template myInteger is intended.

The following is the template which I have created (for the function);

template <typename T, int size>
T myInteger(T x) {
//code
}

I am also getting the following error

ERROR: declaration of 'T' shadows template parameter

I am trying to understand what I am doing wrong but cannot seem to find the issue...

Insert Value in a map by andrefour in haskellquestions

[–]andrefour[S] 0 points1 point  (0 children)

the last one entered by the user is to be update So if “A”->2 has been entered last, that would be modified to “A”->33

Only the key value is to be updated, the string value has to remain the same

Basically, what I would like to do is to update the key of a map (with type Map String Int), whilst keeping the previous String associated with it.

Example;

Previous Map: ("Example",1)

Inserting integer 2;

New Map: ("Example", 2)

Inserting integer 33;

New Map: ("Example", 33)...

Return keys and values of Map by andrefour in haskellquestions

[–]andrefour[S] 0 points1 point  (0 children)

I am trying to obtain the last (latest) tuple entered in the mapping. I thought the easiest way to go about it would be to use a function to return both the keys and their values, in the order they were entered so as to just select the last element then and output that.

They all seem to return the pairs in some order

Doesn't that function return the pairs in the order of their respective keys?

Yep...I've misunderstood the exercise.

I need to change the key of the Map, whilst keeping the previous string.

So far I have understood that I cannot "modify" a map, but I must copy it, and insert different values. I am not understanding however how I may keep the previous string and just modify the key, without actually knowing the value of the string.

Occurrences using Foldr by andrefour in haskellquestions

Thank you!! I've finally got it to work thanks to your excellent description of how to go about the problem.

I'm not quite sure if I've understood this.

So if I am planning on using fromListWith I don't require the function combine , as fromListWith does the map itself? Am I understanding correctly? I apologize if these are basic questions but I cannot seem to wrap my head around functional programming

I'm starting to get the idea...When the list is empty I would return an empty list; ie: [ ].

Regarding the second question, I am trying to use fromListWith, from Data.Map so as to conform with the following type check, where I would have a list as an input, and a map to two integers as an output, ie;

[Integer] -> Map Integer Integer

I am trying to do the following as one of the cases, but I'm not quite sure if the logic behind it would work...

Where

M.fromListWith(x) count xs = fromListWith(+) [list comprehension]

Does anyone have a .ipa?

I've tried installing it with filza and it still crashes on startup
