Complete Modern C++ - Reference

This video tutorial explains the concept of references in C programming, highlighting their importance and usage. It covers how references are created, their need for an initializer, and their binding to a referent. The tutorial contrasts references with pointers, emphasizing differences in memory allocation, initialization, and usage. Through examples, it demonstrates how references act as aliases for variables, sharing the same memory address. The video concludes with a call to practice using references and pointers, preparing for more in-depth discussions in subsequent lectures.
