Not gonna lie. This is a homework help problem. I generally don't have difficulty with the homework problems for my C++ lab but part of my most recent one has just left me scratching my head. The assignment is to write a recursive function which takes any integer and prints that number in the correct order with '*' bookends as well as '*'s in between each digit of the number.
For example, if the function was given 7 as an input it would print *7*. If the input were 3457 it would print out *3*4*5*7*, etc. I'm not asking anyone to flatly give me the code that would yield this result but I really need a hint on this and I don't have the time to go to the departmental tutors at my college.
I was successful at getting *s in between each digit but not doing that in addition to having them surround the entire number. Here's the code I was able to come up with. When I run it with 7 as an input it just prints 7. When I run it with 1234 or another multiple digit number it prints 1*2*3*4...
Since you know x % 10 is going to be a single digit number, don't (recursively) invoke printStarDigit, but instead simply:
cout << (x % 10) ...
Then you know the cout on line 3 (in the recursive stop condition) is always printing the first digit (even in a one digit number), and the cout on line 8 will print all the digits after that. (You will still have the recursive call on line 6.)
Hopefully, I was clear enough to explain what I did to make it work, without giving you the code... But let me know if you still don't understand. Honestly, you are really close, so I wouldn't mind posting the code for you. (Too bad there's no spoiler system on here...)
Thanks Mathhead200, it was a huge help. Your answer really helped me understand how the function was actually working to begin with and I was able to edit the function to make it work as per the assignment.
