so it prints out but is an infinite loop, need to check if they do enter '\n' character how to do that?

cin would stop reading as soon as it encounters a space !
Use getline instead:

gives me weird error of includes atleast one deprecated or antiquated header.
And it doesn't seem to capture # of spaces.

Change <iostream.h> to <iostream>, that's the standard C++ way.

Also delete the line cin >>passage . You're already taking in input with getline(), so no need to do it twice.

And also change int space; to int space = 0; . How can your program ++ if it doesn't know the variable's initial value?

Also put this line: cout<<"the number of spaces is"<<space; outside your for loop. You only want to display this messsage once right?

[edit]

Also (

) , you might want to put a cin.get() at the end of your loop (right after you output your message. This keeps the console open for you to read what the output of your program is. If you don't put it there, your console window will disappear to fast.
You could also run it from a console window you've already opened, but my guess is that you do not yet know how this works.
