Defining a bag Multiset with elements and multiplicity pairs In Ada










-1















I have to meet a specification which says that I have to write a bag type which is a record with discriminant , which is the maximum capacity of the bag in the record I have to put an array that contains element and multiplicity pairs , I have written some code and updated it as well



type TArray is array (Integer range <>) of Elem,Multi;
type Bag (Max : Positive) is record
Data : TArray (1 .. Max);
Pointer : Natural := 0;
end record;


The code has been updated please check and suggest

    Your array type looks incomplete, if it both should contain both elements and multiplicities.

    If you’re going to post code you should really try compiling it! You need an array of a record type, where the record type contains an element and a multiplicity

    I beg your pardon, but where is the question / compilation error / execution exception ?

The answer is quite simple : if you don't have any error messages at compilation phase, it's ok.



Well according to what you described, your code looks good. I have a question about it.



Do you plan to have negative indexes on your type TArray ? If not, why don't you use the same type as your discriminant ?



The only thing is that you'll have only half the values using Positive instead of Integer but in your record, you anyway already start at 1 and thus have the same range as Positive.
