Doesn't output a thing (C++)

Question

In the following code, I tried to make an input (a sentence) and it said, "No output." How on earth is that possible? Which input method should I use? I tried cin, but only gave out only the first word. Tried getline, no output.

Can anyone help? Here's the code:

Answer 1

Use temp += c; to add a character instead.

Answer 2

use cin>>text
