You will discover environments exactly where limits on use of normal C++ language or library characteristics are necessary, e.g., to stop dynamic memory allocation as necessary by plane Handle software criteria.
In contrast to other operators, the compiler will supply a default public assignment operator in your course if you do not deliver one. This assignment operator does memberwise assignment (which is basically similar to the memberwise initialization that default copy constructors do).
Note: C++ employs the unnamed dummy-parameter int to differentiate between prefix and postfix decrement operators.
