C++ Advanced Programming Questions
Here are some advanced C++ programming questions that can help test your understanding of the language and its features:
Memory Management
- Explain the difference between a pointer and a reference.
- What is a dangling pointer? How can you avoid it?
- How does the
newanddeleteoperators work in C++? - What are smart pointers? Explain different types of smart pointers in C++ and their use cases.
- How does memory allocation work in C++? Describe different memory allocation techniques like static, dynamic, and stack allocation.
Object-Oriented Programming (OOP)
- Explain the concept of polymorphism in C++. Provide examples of different types of polymorphism (compile-time and runtime).
- What is the difference between a class and a struct in C++?
- Describe the different types of inheritance in C++ (single, multiple, multilevel, hierarchical).
- What is the purpose of abstract classes and pure virtual functions in C++?
- Explain the concept of encapsulation and how it is implemented in C++.
Templates and Generics
- What are templates in C++? How do they allow for code reusability and flexibility?
- Explain the difference between function templates and class templates.
- How can you specialize templates in C++? What are the benefits of template specialization?
- What are variadic templates? How do they allow for a variable number of arguments in functions and classes?
- Discuss the advantages and disadvantages of using templates in C++.
Exception Handling
- What are exceptions in C++? How do they help in error handling and program robustness?
- Explain the keywords
try,catch, andthrowin the context of exception handling. - What are the different ways to handle exceptions in C++?
- How can you create your own custom exception classes in C++?
- Discuss the benefits and drawbacks of using exception handling in C++.
Advanced Features
- What is the purpose of the
std::moveandstd::forwardfunctions in C++? - Explain the concept of move semantics in C++ and its benefits.
- What are lambda expressions in C++? How do they provide anonymous functions and closures?
- How do you work with regular expressions in C++?
- Explain the role of the
constexprkeyword in C++ and its use cases.
Other Important Topics
- What are the differences between C and C++?
- What are the advantages and disadvantages of using C++ over other programming languages?
- What are some common C++ libraries and their uses? (e.g., STL, Boost)
- How can you improve the performance of your C++ code?
- What are some best practices for writing clean and efficient C++ code?
This list of questions is not exhaustive but provides a good starting point for exploring advanced C++ programming concepts. Remember that the best way to master these concepts is through practice and by working on real-world projects.
