C++ Developer - Parameter Passing: Pass-By-Value and Pass-By-Reference

The video tutorial covers user-defined functions, focusing on parameter passing schemes. It explains pass by value, where a copy of the argument is used, and pass by reference, which allows direct modification of the argument. The tutorial includes coding examples and a challenge exercise to reinforce learning.

What is the expected output when a variable is modified inside a function using pass by reference?

How does the concept of memory location relate to pass by reference?

What are the implications of passing literals versus variables in function calls?

Discuss the challenge presented at the end of the lecture regarding the function 'three times N'.
