Passing Objects to Functions by Reference (&) Explained lecture 3
Stop wasting memory in C++!
In this lecture, we explore the concept of Passing by Reference. When you pass an object to a function by value, C++ creates a copy. However, by using the Ampersand (&) symbol, we can pass the original object itself.
This is not only faster but also allows the function to modify the original data directly!
In this video, we cover:
The Syntax: How to use the & operator in function parameters.
Memory Efficiency: Why passing by reference is better for large objects/classes.
Direct Modification: Watch how changing a value inside the rec() function permanently updates the object in main().
Code Breakdown: A line-by-line analysis of the student class example.
