Defining Question

[LearningMan]

Em I don't know if anybody had this question but anyway here is it:
I was reading about classes and then in the example( the part of it is down there ) I saw that int HumansAge was declared not in the function itself but in the scopes near the name of the function. Maybe I missed something before that topic, but it was easier to write here. So if I understand everything right - we can declare a variable in that scopes near the name? Thanks for answer.

  void SetAge (int HumansAge)
{
Age = HumansAge;
}

In that code snippet, you're defining HumanAge as an argument (or parameter) that's passed into the function.
