Key Takeways

  • Errors are the way the computer communicates with you regarding your code.
  • You’re never going to stop making errors, its a normal part of programming.
  • To solve the errors, just scroll to the top, and try fixing only the first one.
    • Just hit the run button to check if you have fixed it!

Video Addendum

You may have noticed that there was a \n at the end of the example on Repl. That is how you add a new line (enter key in MS Word). Try adding and removing \n and seeing you notice a difference. std::endl can also be used to print out a new line. In general, we prefer using

std::cout << "Hello world";
std::cout << std::endl;

over using

std::cout << "Hello world\n";


  • Sign up for a Repl account.
    • You’ll be able create and store all of your repls so you don’t lose track of them.
  • Sign up for the Slack Community.
  • In a new Repl, write some code where you print some fun facts about yourself.
