Learn and Master C Programming - Passing By Value vs. Passing By Pointer

The video tutorial explains the concepts of passing by value and passing by reference in C programming. It begins with an introduction to pointers and functions, followed by a detailed explanation of passing by value, where two separate memory allocations are made for variables. The tutorial then introduces passing by reference using pointers, explaining how it allows changes to be reflected back in the original variable by manipulating memory addresses. The video concludes with a practical example of dereferencing pointers to modify variable values.

What happens to the value of a variable when it is passed by reference?

What is meant by passing by value in the context of functions?

Explain the difference between passing by value and passing by reference.

How does a pointer variable differ from a regular integer variable?

Describe the process of dereferencing a pointer in a function.
