import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner sc=new Scanner(System.in);
		while(sc.hasNext()){
			int n=sc.nextInt(),count=0;
			for(int i=1;i<=n;i++){
				String s=sc.next();
				if(s.matches("\\b[cC].*\\b")){
					System.out.println(s);
					count++;
				}
			}
			System.out.println(count);
		}
		sc.close();
