Reading Code:

• myClass t;

t.move();
• Declare a variable (and call it 't') which is of the type myClass
• Then, call the function ( '()' ) move ('move'), which is within ( '.' ) the variable t ( 't' ).

• may be any type currently defined in C++, or a type that you have already defined (another class, etc..)
• may be as many as you wish...

Classes
