Arrays - Removing duplicates

[@SamFourieOfficial]

I am currently in grade 12 and writing my final exam tomorrow. I have used your videos throughout my whole high school career. I just wanted to say thank you so much for making these videos. You have seriously helped me so much. I don't think you even know how many people you actually help. You are really awesome. Keep it up.

@@jono5998 it is actually crazy to come back 2 years later, my knowledge in IT is so much better and crazy to think back to when I was struggling with this stuff 😂

How do you use sets in delphi?

[@MrLongITandCAT]

Use IN for example, if sLetter[ I ] IN [ 'a' .. 'z' ] then

Hello mr long how would one add up the specific values in an array for example //on form activate i := 1 for k := 1 to 100 do begin if arrbreeddog[i] = arrbreeddog[i] then begin arrfoodate[i] := arrfoodate[i] + arrfoodate[k] end; end; inc(i) it works all fine and well until you start to try and add the food ate by 3 dogs of the same breed or more because then the program adds like : german shepard 1 kg german shepard 1 kg german shepard 1 kg first it plusses 1 and 1 to form 2 but then it plusses the first amount again and the 1st + 2nd +3rd to form 4kg. Extra info my program takes in different breeds (by a dog code entered into a edit box for example 1 is the code for german shepard) of and then when you press a button it uses the value in the spin edit as the amount food ate and then displays the final values in a rich edit so it has to show german shepard 3 kg instead of each individual value (so the problem is that I could enter a german shepard then a husky then another dog and then husky then german then german (any random order) and then the program has to take only german shepards and plus their amounts and take the husky's amount and then display only 1 line per breed) Thank you so much for all the help threw the years : )
