I can't get this for loop to change the 0 to a 1. I need it to count to 30 by 5s. I would appreciate any help. Here is the code.

After watching a video I learned that
int x = Convert.ToInt32(Console.ReadLine());
and
int x = 0
x = int.Parse(Console.ReadLine());
essentially seem to be the same thing...why is that, and when would one way come in handy over the other?

Can someone explain this code to me....
class ReverseNumberDemo
{ public static void main(String args[]) {
int num=123456789;
int reversenum =0;
while( num != 0 ) {
reversenum = reversenum * 10;
reversenum = reversenum + num%10;
num = num/10; }
System.out.println("Reverse of specified number is: "+reversenum);
}
}
the thing I don't get is the reversenum part......isn't reversenum=0 so wouldn't reversenum*10=0

3 odpowiedzinums = [i**2 for i in range(5)]
print(nums)
[1, 4, 9, 16]
"..what will this create..?"
"Correct" answer was:
"A list of even numbers between 0 and 18."
9 is not an even number tho.
Is this a typo or am i missunderstanding/missinterpreting?

In the continue Loop -
i = 0
while True:
i = i +1
if i == 2:
print("Skipping 2")
continue
if i == 5:
print("Breaking")
break
print(i)
print("Finished")
It shows the output being
"1
Skipping 2
3
4
Breaking
Finished"
Why are the last three lines not
"Breaking
5
Finished"
Where it shows print(i) after break?
