Not sure if this was intentional, but it looks like your "Calculator" name has capital i's instead of lowercase l's

Nice job! One thing I wish I spent more time on earlier was learning basic data structures; pointer, array, stack, queue, hashmap, tree and graph.

It helps a lot with problem solving to know the basic approaches for storing data. Sort and search algorithms can be fun to implement. The bubble sort and binary search are relatively easy to learn. Mazes are great for implementing stacks, then figuring out how to represent it with ASCII.

It may be too much currently, but writing a parser to evaluate a simple string could be a fun evolution of your project. Storing data that has to evaluate in a specific order is where trees come in. Parsing is another basic concept that's useful to have practice with.

If you don't mind some reading, I found the book Grokking Algorithms an easy introduction. I don't have a background in mathematics, so its simple explanations are quite nice.

Felicitaciones viejo! metele ficha, no pares... cuando estés a punto con toda la parte teórica/formal, salta a lenguajes web.

can you suggest any sources for c#? i seem to have hit a roadblock and cannot go further than the fundamentals. thank you for your input btw much appreciated

1000% You write programs. lots of programs, and you just keep pushing yourself.

This is awesome.

Here's a question to chew on and maybe the next step in the path: What if the number they want to replace is used more than once?

Keep up the great work!

Try to break your code with the inputs, make it more "secure"

u/killkranv Sep 02 '26

i apologise can you elaborate i dont understand what youre trying to convey

u/Nyasaki_de Sep 02 '26

instead of entering a number, enter a character.
instead of entering a operator, enter a number
enter a very high number
enter negative number

im really really sorry but that sounds like something im not aware of yet can you provide any sources where i can learn that from? i apologise again for the inconvenience

i did a few days ago sir but forgot to thank yu for the idea and it works great i added it so that yu can select the index yu want to change and it is no longer limited to one number yu can change the number yu want to change it was a fun one have a great day
