char group variable declaration

Question

In Basic Concepts - variable topic at this course there's a declaration of a variable char like this:
char group = 'Z';

What is the function of group? I have only seen group in regex

Answer 1

The group has none kind of function
You are declaring a character constant and "group" is just the name for 'Z' or say the name of the variable (char)

Answer 2

haha thank you ,Rahul Verma . I didn't noticed it was only the name of the attribute XD
