What is numbers on test 3, which is calculated incorrectly?

Answer 1

I tested your code and it seems to work ok.
I tried entering 0123210, which returned false, so maybe this is the problem.
My suggestion:
Turn your integer into a string.
Reverse the string.
Compare the reversed string to the original string.
You may find this approach a lot simpler.

Answer 2

You are manually defining the length by this line,
int a=5
either take in a string and assign to a the length of string. And then convert that string to number . Or you can follow what Rik Wittkopp suggested

Answer 3

Thanx for all! Martin's advice helped.
How did you find out about libraries? On the course, "the reverse" did not find such a thing.

Answer 4

How to find zero at beginning of a number (int)? 010 for example
