Give a scenario when the preprocessor must be used in C++ since
there is no way to do such within the language. -
correct answer ✅It must be used to establish #include guards.
Mr. X proposes to the ISO C++ committee a really cool language
feature that he would like to see added to C++. At the ISO meeting,
people ask Mr. X to explain how his proposal does not run afoul of
the zero-overhead rule.
Clearly explain what the Zero-Overhead rule as a language design
objective means with respect to C++. -
correct answer ✅The zero overhead rule is the language design
guideline that if you don't use a language feature then there is no
overheads present in the generated code with respect to that
feature.

Briefly explain what the main practical difference is between the
modular programming paradigm and the object-based paradigm. -
correct answer ✅A module in modular programming permits only
one instance of the module.
Object-based can have an arbitrary number of instances.
Clearly explain what the generic programming paradigm is. -
correct answer ✅The generic programming paradigm allows one
to specific type/constant parameters associated with the definitions
of programming constructs.
When all parameters have been specified, the compiler/execution
environment generates the code for those definitions.
Suppose you have a type called MYTYPE. Write the correct
overloaded bit shift operator to handle reading MYTYPE from a C++
stream.
Your code must work for any character type and/or character trait
used with the stream. -
correct answer ✅template <typename Char, typename CharTraits>
