Arrays as Class, Vector Implementation, and STL: Vector & Pairs

Welcome to Week 10! 🎉 This week, you'll explore how arrays can be encapsulated within classes, understand the internal workings of dynamic arrays (vector implementation using arrays), and master the STL’s vector and pair containers for efficient problem-solving. As software engineers, learning to implement data structures ourselves is crucial—not just to understand how each function works but also to use them efficiently in real-world problems. A deep, low-level understanding helps in writing optimized code, making the right trade-offs, and designing scalable systems. Let’s dive in! 🚀
