Learn and Master C Programming - Why Do We Need Pointers?

The video tutorial explains the necessity of pointers in C programming. It begins with setting up a project in Visual Studio and demonstrates swapping two variables using a third variable. The tutorial then converts this logic into a function and uses debugging techniques to explore why the swap doesn't work as expected due to pass by value. Finally, it introduces pointers as a solution to the problem, setting the stage for the next lecture.

How can you verify that two variables are not the same when passed to a function?
