What is the correct way to print quotation marks?

🔗

Hint.

🔗

Answer.

Single quotes are printed using \'

🔗
Double quotes are printed using \"

Solution.

Within any string (deliminated by double quotes " "), a double quote needs to be “escaped”, that is, preceded by a backslash. Single quotes are actually okay within strings, but it is also okay to escape them. If you’d like to use a single quote within something enclosed by single quotes however, then you need to escape that single quote (but double quotes are okay, surrounded by single quotes).
