- Can you edit the question and describe exactly what kind of problems you are having? We need more detailed information, along with some description of what you've done to try and resolve the problem. As this question stands, it is too vague.Cliff B– Cliff B2018-07-06 11:25:11 +00:00Commented Jul 6, 2018 at 11:25
- Thank you for the reply. I have edited my question. Sorry for being unclear with my question. Hope it is clearer nowTrevor Lim– Trevor Lim2018-07-07 12:24:55 +00:00Commented Jul 7, 2018 at 12:24
- I don't quite understand your code but maybe try a different approach.. Possibly performing luhn's algorithm first and then validating card length at the end. Not all card lengths are 16 digitsPaleFire– PaleFire2018-07-09 08:46:52 +00:00Commented Jul 9, 2018 at 8:46
- Also you shouldn't need to have a variable after the '%' symbol. i = CC % 10 would give you the last digit, which you can then subtract from CC and divide CC by 10 for next digit - sorry if this is a bit vaguePaleFire– PaleFire2018-07-09 08:50:11 +00:00Commented Jul 9, 2018 at 8:50

How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. segmentation-fault), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
