Complete Modern C++ - Union - I

The video tutorial introduces unions in C programming, explaining how they allow multiple members to share the same memory space, which is beneficial for saving space, especially on embedded platforms. It highlights the disadvantages, such as the inability to determine the active member and the need for manual implementation of constructors and destructors. The tutorial provides an example of creating a union with an integer and a character, demonstrating initialization and memory usage. It concludes by discussing the size of a union, determined by its largest member.
