Line 38 and 39 just check if a function that always returns false is false and if so, prints “💩\n”. (C++ uses the bit shift operator for file IO for some reason)
Line 41 creates a vector of shared pointers to an abstract class, or in other words, an array of functions. Each function prints the emoji, mostly the same as the name, but not always. ( 🍒 is the exception, it prints “🍉\n”)
43 and 44 just loop over the array and call every function inside, printing a bunch of emoji.
Line 46 returns the result of std::rand(), but because the programer forgot to call srand, the result is always the same (1804289383 for me).
(There are also a few missing includes, but I doubt this is intentional)
