Why is there no call to the constructor? [duplicate]

by

Nope. Your line Class object(); Declared a function. What you want to write is Class object;

Try it out.

You may also be interested in the most vexing parse (as others have noted). A great example is in Effective STL Item 6 on page 33. (In 12th printing, September 2009.) Specifically the example at the top of page 35 is what you did, and it explains why the parser handles it as a function declaration.
