Inputting spaces from cin?

I am working on a movie rater program and in it I ask the user to input movie titles. Cin does not allow the user to type in spaces if the movie has a space in it. For example, "The Hulk" will be typed in as "TheHulk". I am trying to implement a function that will break up the string at the capital letters and insert a space. So if the input is "IHaveADream" I want the program to return "I Have A Dream". You may assume the first letter is a caps (and even if not you will still get a reasonable result; so "badNews" should still return "bad News"). The function is called string breakStringAtCaps(string in);. I'm thinking I need to use the isupper function somewhere. Any ideas on how I can implement this function to my program?
How would I implement that code wise? I've never used that
How would I implement that code wise?

instead of
 
    cin >> movie_title;

you would have
 
    getline(cin, movie_title);

It needs to be in a function

Trying to implement the string breakStringAtCaps(string in) function
One way to do this is to use a for-loop to examine each character in the string. If it is an upper-case letter, then insert a space at that position.

To find the length of the string: size()
To test for upper case: isupper()
To insert a space: insert()

The insert is easy enough, but a word on that. The string insert function allows several different possibilities, though we want to insert only a single character, use the syntax " " which really is a string containing a single space. Also, add 1 to the loop counter afterwards or you might test the same character again on the next iteration of the loop.
