Question

I want a possible way to detect int next to any character or string. for example
88+34
I want my code to detect and use 34 as it is the next integer to + sign. How is it possible?

Answer 1

Use a Regular Expression which matches a non-digit followed by one or more digits, then return the digits.
The actual expression varies a little with language, but will be similar to /[^\d](\d+)/.
