Palindromic number
In order to find out if a number is a palindromic number, the input needs to be spilt up and reversed. How do you split it? Thanks

get last digit (using %) and divide by 10 until number reach 0 ^^

You can also try this as well...
1.Convert `n` in to string using to_string(int) function...
2.scan the string from beginning and end, up to middle..and check that if corresponding elements are equal or not..
If yes , return true
Otherwise false

by converse operation (assuming you want to join them in reverse order):
initialize a variable to zero (or use the previous one)
for each digits, multiply the variable by 10 and add digit to it...

you doesn't need an array if you use another variable (initialized to zero) to store the resulting reverse number: then you do both operation in once loop ;P

Yep, thanks again!

Muhammad Hamza use strings
It might cause a bug in your program if you use division or other ways

And how do you join them back?

Oh and what about storing the individual digits?
I understand that an array should be used, but how do you create an array thatâs just as big as the number of digits?
