Answer 3

I am not very familiar with C++, but I know that in Java the "main" method can be declared as static, whereas in C++ "main" cannot be declared as static. More details on "main" in C++ can be found in this article
https://docs.microsoft.com/en-us/cpp/cpp/main-function-command-line-args?view=msvc-160
Also, normally when I write a "main" method in Java, I give it one argument, args, but the article instructs the use of two arguments, argc and argv. I'm not sure if this is a fundamental difference or just a matter of convention, but it may be worth mentioning
