Question

Hi friends, I wrote this program using java but ..
Exactly what happens when we use the for command once and then the while-do command again instead of while, I have seen changes, but I could not define them because I want to write notes and learn that. Please write notes about the change that is happening

Knowing the code is correct, but there is a problem with Solo Learn, please help me by using another code editor.

It is preferred with writing comments on the code for explanation

Answer 1

do-while, while, and for are all kinds of loops. You can convert them to each by doing small changes and will see no difference.

Answer 2

No, when I use for on the same code and do while, I get errors .. Please, when you answer me, answer me by writing the complete code
Then, explain what happened because I do not know why errors appear
