- 1. How the member functions in the container can be accessed?
Options- A. Iterator
- B. Indirect
- C. Both a & b
- D. None of these Discuss
Correct Answer: Iterator
Explanation:
The container manages the storage space for its elements and provides member functions to access them, either directly or through iterators which reference objects with similar properties to pointers.
- 2. What does the sequence adaptor provide?
Options- A. Insertion
- B. Deletion
- C. Interface to sequence container
- D. None of thse Discuss
Correct Answer: Interface to sequence container
- 3. How many items are presented in the associate container?
Options- A. 2
- B. 3
- C. 4
- D. 5 Discuss
Correct Answer: 5
Explanation:
There are 5 items presented in the associate container. They are set, multiset, map, multimap and bitset.
- 4. How many parameters are present in mismatch method in non-sequence modifying algorithm?
Options- A. 1
- B. 2
- C. 3
- D. 4 Discuss
Correct Answer: 4
Explanation:
There are four parameters. They are first1, last1, first2, predicate.
- 5. What kind of object is modifying sequence algorithm?
Options- A. Function template
- B. Class template
- C. Method
- D. None of these Discuss
Correct Answer: Function template
Explanation:
It is a group of functions and implemented under algorithm header file.
- 6. What is the kind of execution does sequence point allow?
Options- A. Non-overlap
- B. Overlap
- C. Concurrent
- D. None of these Discuss
Correct Answer: Non-overlap
Explanation:
To resolve all the side-effects in the program, the sequence point should not be overlapped.
- 7. Which keyword is used to declare the min and max functions?
Options- A. iostream
- B. string
- C. algorithm
- D. None of these Discuss
Correct Answer: algorithm
Explanation:
Algorithm header file contain the supporting files needed for the execution of these functions.
- 8. How the different permutations are ordered in c++?
Options- A. Compare lexicographicaly to each other elements
- B. By finding the highest element in the range
- C. By finding the lowest element in the range
- D. None of the mentioned Discuss
Correct Answer: Compare lexicographicaly to each other elements
- 9. Where does the allocaters are implemented?
Options- A. Template library
- B. Standard library
- C. C++ code library
- D. None of these Discuss
Correct Answer: Standard library
Explanation:
Allocaters are implemented in C++ standard library but it is used for C++ template library.
- 10. Explain storage qualifiers in C++ Discuss
Correct Answer: i) Const - This variable means that if the memory is initialised once, it should not be altered by a program ii) Volatile - This variable means that the value in the memory location can be altered even though nothing in the program code modifies the contents iii) Mutable - This variable means that a particular member of a structure or class can be altered even if a particular structure variable, class, or class member function is constant
