What the quiz covers
This quiz is the harder follow-up to our basic C++ quiz, aimed at product-company and systems interviews that probe modern C++ (C++11 to C++20). The 25 questions are grouped into 9 areas, shown above each question: Move semantics, Smart pointers, Core, OOP, Modern C++, STL, Templates, Undefined behaviour, Concurrency.
A sample question explained
"What does std::move actually do?" The answer is Casts its argument to an rvalue reference so it can be moved from. std::move is just a cast; the move constructor or assignment does the real work. Many candidates think std::move moves data; it only enables a move by changing the value category.
More questions you'll meet
A few of the other Advanced C++ questions in the bank:
- Which smart pointer expresses sole ownership and can't be copied?
- RAII means
- Why should a base class with virtual functions have a virtual destructor?
- What does override do on a member function?
- What is the type of x in auto x = {1, 2, 3};?
- What can happen to iterators after vector::push_back?
- What is the time complexity of std::sort?
Study tips
- Write a small class with a move constructor and print when copies and moves happen.
- Learn which operations invalidate iterators for vector, map and unordered_map.
- Aim for at least 20 out of 25 on two separate attempts before you treat Advanced C++ as revised; one lucky score can hide gaps.
Questions and options are shuffled on each attempt, so a retake is a fresh test. The Advanced C++ questions were written by Uncodemy for practice; they aren't copied from any exam or company test.
