Question
Q2 [C++11] Which of the following statements is false?a. The C++ standard redesigned the classic C++ stream classes, which processed only chars, as class templates with specializations for processing characters of types char and wchar_t, respectively.
b. C++11 added type char64_t to handle the new double-width Unicode characters.
c. The size of type wchar_t is not specified by the C++ standard.
d. C++11's new char16_t and char32_t types for representing Unicode characters were added to provide character types with explicitly specified sizes.
Answer
This answer is hidden. It contains 68 characters.

Q3[C++11]: Which of the following statements about inheriting base class constructors is false?

b. If an inherited base-class constructor has default arguments, the line of code in Part (a) causes the compiler to generate a derived-class constructor with the same default arguments.
c. By default, each inherited constructor has the same access level (public, protected or private) as its corresponding base-class constructor.
d. If the derived class does not explicitly define constructors, the compiler generates a default constructor in the derived classeven if it inherits other constructors from its base class.
