Hi please how the argument (int index) became inside [index]

[@ProfessorHankStalica]

If I understand the question, that's how pass by value works. The contents of the argument get copied into the parameter. A parameter is a type of local variable you can use within the function. So, the value inside the parameter is used how you would use any other variable.

What happens if you run this on an array of Foo? for e.g. if you've declared Foo a[10] instead of Foo a, then what would we get on calling a[2] ?
