Intro C++

I'm trying to write a program that edits a text file to replace all consecutive spaces with a single space.  The editing of the spaces is what's giving me problems.

}

while(! fin.eof())
    {
        fin.get(next);

         if(isspace(next))
             count = count + 1;
        
         if(isspace(next) && count >= 2)
         {
            fout << ' ';
            count = 0;
         }
       
         else
         {
            fout << next;   
            count = 0;
         }
    }
    fin.close( );
    fout.close( );
       
    }

Basically, I'm trying to add 1 every time a space is encountered as some sort of comparison, when it's = 2 it gets replaced with single space.  So far it outputs the text unedited.  Any help would be appreciated.


int main() {
 return system("sed 's/  / /g'");
}
