The following code is an example from the exercise :

#include <iostream>

int main() {

  std::cout << "Dear Self,\n";
  std::cout << "Build a VR game.\n";
  std::cout << "1/1/2020, New York\n";


Why do you need the multiple lines of code? why couldn’t you just use a single code line with the \n’s? as follows:

#include <iostream>

int main() {

  std::cout << "Dear Self,\nBuild a VR game.\n1/1/2020, New York\n";

I think the purpose is to get used to the syntax. Repeating is helpful for some to learn.
