C++ Tutorial for Beginners 29 - Binary Files in C++ | Structure In Binary File I/O

Welcome to this course on C++ Tutorial for Beginners. In this video we will see How to use File I/O in C++.
Using Input/Output Files
stream - a sequence of characters interactive (iostream)
cin - input stream associated with keyboard.
cout - output stream associated with display
file (fstream)
 ifstream - defines new input stream (normally associated with a file).
 ofstream - defines new output stream (normally associated with a file).

C++ is general purpose, compiled, object-oriented programming language and its concepts served as the basis for several other languages such as Java, Python, Ruby, Perl etc.

The goal of this course is to provide you with a working knowledge of C++. We'll start with the basics, including syntax, operators, loops, and functions. This Course will explain you how to use data structures and create your own Functions. This Course will show you the details of the powerful object and template systems so you can create useful classes and objects.

good. you should use reinterpret_cast rather than C-style cast. file.read(reinterpret_cast<char*>(&p), sizeof(p));
also you should never read a non-initialized object because it yields Undefined Behavior:
int p;
cout << p;// UB
* usually you don't need to close file explicitly, the destructor foes it for you. you only need that if you want to save changes then you need to use the same stream for another file or even for the same for another reason.

Dude i feel like this is the most underrated channel because most of the people watches it subscribes it but never visit again to watch regularly. Why? Maybe because of no catchy thumbnail?

Thankyou. I've wasted so much time on other tutorials that didn't work. This one worked :)
Are you familiar with game loops and proper frame capping that doesn't fry my CPU ?
