To which type of class, We can apply RTTI?

Correct Answer: ellipses operator

Explanation:

The ellipses operator can be represented as (?).

Correct Answer: A function is limited to throwing only a specified list of exceptions.

Explanation:

C++ provides a mechanism to ensure that a given function is limited to throwing only a specified list of exceptions. It is called as exception specification.

Correct Answer: 2

Explanation:

Class hierarchies promote reuse in two ways. They are code sharing and interface sharing.

Correct Answer: A conversion constructor declared with the explicit keyword The compiler does not use an explicit constructor to implement an implied conversion of types It?s purpose is reserved explicitly for construction

Correct Answer: 2

Explanation:

There are two formats for initializers in C++ as shown in the example that follows. The first format uses the traditional C notation. The second format uses constructor notation.

int foo = 123;

 

int bar (123);

Correct Answer: Dynamic arrays

Explanation:

Vectors are sequence containers representing arrays that can change in size.

Correct Answer: Iterators

Correct Answer: According to one-definition rule, C++ constructs must be identically defined in every compilation unit they are used in As per ODR, two definitions contained in different source files are called to be identically defined if they token-for-token identical The tokens should have same meaning in both source files Identically defined doesn?t mean character-by-character equivalence Two definitions can have different whitespace or comments and yet be identical

Correct Answer: - Friend classes are useful when a class wants to hide features from users which are needed only by another, tightly coupled class - Implementation details can be kept safe by providing friend status to a tightly cohesive class

Correct Answer: A Stack is a linear structure in which insertions and deletions are always made at one end ie the top - this is termed as last in, first out (LIFO) Stacks are useful when we need to check some syntex errors like missing parentheses
