153 is Armstrong number, as well as 371. for me gives a correct output

Answer 2

Mihaly Nyilas in vs code this code not give correct output

Answer 3

did you doublecheck the code in vscode? There might be a typographical error.
you probably made an error is the "is" and "is not" message...
or maybe did not copy the
originalNum = num;

Answer 4

Bob_Li actually I asked chat gpt it says amstrong number convert into float because of pow function then I removed pow and used multiplying 3 times then code excited properly you try with you own vs code same code of me please and tell me

Answer 5

I guess it depends on your machine and compliler.
It didn't give me the wrong answer when I tried it on my laptop.

But yes, pow could give you sneaky bugs because of it's implementation.
I never realized that.

Bob_Li am using mingw c++ I don't know but 153 it gives me it's not amstrong when I use pow gpt say it happens because change datatype

I made a little modification of the code, so it outputs armstrong numbers up to 10000.........
