Functions/Methods
Classes- A parameter to a constructor optional - correct answer ✔True-
default parameters
Classes- Initializer list - correct answer ✔Initialization list is used to initialize
the data members directly
Classes- Explicit Constructor - correct answer ✔Avoids automatic type
conversion
Classes- Constant member functions (accessor) - correct answer ✔A
member function that examines but does not change the state of its object,
const functions
Classes- Constant member functions (mutators) - correct answer ✔A
member function that changes the state of its object, non-const functions
Interface - correct answer ✔#include in .cpp files
,Benefits of Preprocessor commands - correct answer ✔Guards against
multiple inclusion of .h files
Scope-resolution operator - correct answer ✔:: symbol, used to identify the
class corresponding to each function
True or False: Function signatures must match in both interface and
implementation - correct answer ✔true
