Correct Answer: outside the regular code
Correct Answer: Exceptions are used when postconditions of a function can be satisfied.
Correct Answer: 3
Explanation:
C++ allows us to parameterize directly three kinds of entities through templates: types, constants, and templates.
Correct Answer: It will have certain data types to be fixed.
Explanation:
In the template specialization, it will make the template to be specific for some data types.
Correct Answer: A template is a formula for creating a generic class
Correct Answer: Exception object is created only if an error actually happens
Explanation:
If an error occurs in program, then only exception object is created otherwise, It will not be created. So it?s expensive to use in the program.
Correct Answer: namespace std
Explanation:
:As these are standard exceptions, they need to be defined in the standard block, So it is defined under namespace std.
Correct Answer: Separation of interface from implementation
Correct Answer: The variable is visible to its block and to it?s derived class
Correct Answer: Information about an object?s datatype at runtime
Explanation:
With the help of RTTI, We can get the information about the data type at the runtime.
