The phrase “Object Oriented” means that a program compiles in segments, not line-by-line. For example, in C++, you can create a method that contains different attributes, such as string name1 = "death-waltz"; as a part of the constructor, and then call it again CUSTOMIZABLY, meaning you can replace it with new characters, if the string is not immutable. In non-OOPLs, you cannot do this to my understanding. Hope this helps!
Just so you guys know, cout does not stand for character output, as you said in lesson 3: “Output”. Rather, it stands for console output. I understand some people refer to it as C++ out, C out, character out, create output, etc., but I do believe the actual meaning is console output .

Can I use c++ to create games? If not what code can I use?
Modern desktop games like Half-life, Doom and so on are mainly written in C++ with API libraries for graphics, such as: OpenGL, DirectX, Vulkan. There are also lots of complicated math involved so you may consider brushing up your knowledge in group theory, probability theory, calculus and etc.

у меня такой вопрос в упражнение компиляций это обязательно знать или это всторостепенное
what is std used for? and what is the difference between int main() and void main()?
you can avoid using std everytime just add using namespace std; before the main function/ after adding the libraries. Int and void are return types of the main function. Int main will return an integer and void main returns void/null(basically nothing)
