C++ Arrays vs Vectors: When to Use Each | Beginner's Guide | C++ for Placements

Описание: Welcome to Lecture 3 of our C++ for Beginners series! Now that you understand variables, it's time to work with collections of data. In this video, we'll explore Arrays and Vectors - two fundamental ways to store multiple values in C++.

We'll compare both approaches so you understand exactly when to use arrays versus vectors in your programs.

In this video, you'll learn:
• What are arrays and how to declare/initialize them
• How to access and modify array elements using indexes
• The limitations of traditional C-style arrays
• Introduction to std::vector - the dynamic array
• Essential vector operations: push_back(), pop_back(), size()
• Key differences between arrays and vectors
• When to use arrays vs vectors in real projects
