Question

Suppose I have a string value “110099” and I need to increment the substring value “00” in steps of x until y and wrap to zero , if x =10 and y=90 i.e “111099”,”112099″ … and after “119099” the string value is “110099”. Can anyone please help how do I start with. thanks for your time.

EDIT:
Changed the question to be generic.

Answer 1

1. Take the substring you want to increment.
2. Cast it to integer values.
3. increment by 10 and then %100.
4. Cast back to string.

5. Replace it back in your original string.

   Code is pretty simple.
