Why does this stop at spaces?

Question

https://code.sololearn.com/c4ijn3MBIiP6/?ref=app

Input anything with a space and it will stop once it encounters the space. Why?

Answer 1

In line 7, use getline(cin, str);

Then you can read a whole line, including spaces.

Hope that helps :)

Answer 2

Replace that line completely 😊

Answer 3

Ah. I get it. Thanks!

Answer 4

Where in line 7? Replace cin, or after it?
