C++ is one of the most common languages asked about in technical interviews. It is widely used because of its speed, flexibility, and support for both low-level programming and advanced features like OOP and templates.

In this guide, we’ll go through important C++ interview questions with answers that cover the basics, core concepts, and advanced topics.

Here's the list of interview question articles:

• C++ Basics & Program Structure
• C++ Core Concepts & Memory Handling
• Object-Oriented Programming (OOP)
• Exception Handling & Templates
• STL (Standard Template Library)
• Advanced Topics & Design Patterns

Preparing for C++ Programming Interview Questions

C++ is one of the most asked-about languages in interviews because it combines low-level memory management with high-level object-oriented features. To do well, you need to understand core syntax, OOP concepts, STL, memory handling, and advanced features.

• References
• Dynamic Memory (new/delete)
• Memory Leaks
• Shallow vs Deep Copy
• Smart Pointers

2. Object-Oriented Programming, Exception Handling & Templates

• Object Oriented Programming
• Exception Handling
• Templates

3. Advanced Topics & Design Patterns

• STL
