Question

How do you write/ask user to input 10 integers and print out largest odd number? Stuck with Loops. Thanks

Answer 1

Ok, in what language do you work?

Answer 2

Python 2. 79
thank you

Answer 3

ok, so first we need to input 10 integers, right? can you make a loop for that?

Answer 4

unsure, but seems like loops is something should.

Answer 5

ok, let's start with a single input and then add a loop for 10 inputs
How would you get get a single integer?

Answer 6

int(raw_input('enter int....'))

Answer 7

ok, do you know to make a loop that runs 10 times?

Answer 8

tried for x=int(raw-input.....
while (x < 11):.....

Answer 9

no it wouldn't work. your loop is depended on the input, and it shouldn't be.
How about:
```python
for i in range(10):
pass
```
This will loop 10 times wouldn't it?

Answer 10

It will do nothing really, but will loop 10 times.

Answer 11

it seems to only give me 1 int.
haven't learn 'pass' yet.

Answer 12

Now, if we ask for input inside the loop:
```python
for i in range(10):
x = int(raw_input('enter int....'))
```
This will ask the user to enter 10 integers in a row, each time the value will get into x.
So we have our first step, asking for 10 numbers

Answer 13

Now we have to save the numbers we got from the user. Are you familiar with lists?

Answer 14

been trying to understand for/while. once done, go to list

Answer 15

it will be very annoying to make it without lists. in fact, without lists we are pretty much have to do it without loops, which will be very ugly. (imagine 10 input lines in a row into 10 different variables instead of what we have here.. you can see how bad it starts)

Answer 16

thank you. i will read up on list and try again. i didn't want to ask input 10x. it would have been very annoying.
Have to go. thank you so much

Answer 17

Ok, cya =)

Answer 19

Another thing to think about is if you need anything other than the largest odd integer. If not, then why save anything other than the largest odd one you see?

Answer 20

@e.mccormick No reason really =)
I thought it would make it simpler to break it to smaller steps.
First getting the numbers, then finding the maximum odd. Then after it all works and covers everything to optimize it and combine the loops and do some refactoring if needed

Answer 21

With just one loop, you take it in, evaluate, and replace if needed. Then, after that loop, you print the result. Simpler. Cleaner. Only need 1 global and 1 local variable with 2 if statments. And no need to have learned arrays yet.

Answer 22

Yes from the point of not needing knowledge about arrays I agree
I know what you mean, I also see the final solution
But from what I've seen this approach does help to simplify problems even if it seems dumb at first..
I've seen it taken in more complicated problems and I just liked the way it turned out at the end, that's all.
It is arguable of course, but that's the way methodologies always are hehe

Answer 23

Thank you e.mccormick and thanks again pitamar. I'll start reading and working.
