Answer 1

co is variable that counts number of odd numbers in your list
So co+=1 is increasing when number is odd (i.e else part indicates odd numbers)
Then in line 18 I checked if co is 0 or not
If co (number of odd numbers) is 0 then made pro (product of odd number) as 0

Answer 2

In your input (i.e 10 20 30 40 50) there is no odd number so product of odd number display output 1 as you declared pro=1 in your code.
So the solution can be you can add another variable to check if there are odd numbers in your list Or not. If there is no odd number then you can set your pro=0 so output of product of odd numbers comes out to be 0 instead of 1.

Answer 7

Sachin Pradhan what's the expected result if no odd numbers? (and what's the expected result if no even numbers)

as stated by Mayank Matwa, you must take trace if no even and no odd values, then if either so, output specific value expected for the one wich are not presents ^^
