Because curly braces create scope in C++. So you created an "unnamed"
scope in which you created a QCoreApplication instance called app on the
stack. Once a scope is exited (the closing curly brace) all variables
declared inside the scope go "out of scope" and hence your
QCoreApplication object is destroyed.

Whatever you prefer.
