Don't understand this section of code.

What does this code do?

Rectangle::Rectangle():
itsWidth(5),
itsLength(10)
{}

"Rectangle" is a class name. "Rectangle()" is a member function. "itsWidth" and "itsLength" are private member variables.

Thanks.

It explicitly calls the members' constructors and passes them those parameters. In this case, assuming the members are of basic types, it initializes itsWidth to 5 and itsLength to 10.
