Arrays and Vectors in C++

 Arrays and Vectors in C++: Advanced Data Handling

Arrays and Vectors are the fundamental containers for managing collections of elements in C++. While arrays provide a fixed-size, high-performance way to store data, vectors offer the flexibility of dynamic resizing, making them indispensable for modern software development where dataset sizes often change at runtime.

This module provides practical, hands-on C++ container exercises. You will master index-based access, efficient iteration techniques, and critical algorithms for sorting, searching, and filtering data within these structures.

Core Technical Concepts Mastered:

  • Static Array initialization
  • Dynamic std::vector resizing
  • Linear and Binary searching
  • Element-wise mathematical operations
  • Memory management & bounds checking
  • Array symmetry and Palindromes
