I have an array of integers. Like 1, 2, 3, 4, .... Is it possible to make something similar like regex searches for text? E.g. I want to search for 7.*7. To see if there are two sevens in it. Or 1.7.1. And so on.

CodePudding user response：

Is it possible to make regex searches on it, like for text.

Well,

No

Regex cannot be applied to other data structures than strings / text.

You can easily apply search rules using a lambda function and std::find_if() et al. with standard container classes though.
