while ((ch = getchar()) == ' ') equivalent in c++

[ElleJay]

I believe this is c code, so what is the equivalent of this line in c++?

  while ((ch = getchar()) == ' ');

Something like this:

char ch;
while (std::cin.get(ch) && ch == ' ')
    ;

This is the whole code:

    char getItem() {
        char ch;
        while ((ch = getchar()) == ' ') ; 
        return ch;
    }

I'm confused as to what the while loop means.

It's skipping spaces. When it finally reads a non-space, it returns that character.
So the function could be called "return_next_nonspace_char".
