getline (cin, str); and getline (cin, str, '\n'); both means the same thing. The third parameter specifies the delimitation character. When this character is met, the rest of the input will be ignored. The default delim for getline function is the newline character '\n'. We actually have pretty legit official documentation!

I saw not difference in the output. Maybe because the whitespace of the newline was ignored.

I think the first one adds the \n character to the end of the string while the next one just takes string as input and assigns it to str variable
