C :

#include <stdio.h>
void main()
{
	int a,b;
	scanf("%d%d",&a,&b);
	if(a>b)
		printf("Da\n");
	else if(a==b)
		printf("Deng\n");
	else
		printf("Xiao\n");
}

C++ :

#include<iostream>
#include<cstdlib>
#include<cstdio>
using namespace std;
int main()
{
	int a,b;
	cin>>a>>b;
	if(a>b)
	  cout<<"Da";
	if(a==b)
	  cout<<"Deng";
	if(a<b)
	  cout<<"Xiao";
	return 0;
}

Pascal :

var a,b:longint;
begin
readln(a,b);
if a<b then write('Xiao'); 
if a>b then write('Da');
if a=b then write('Deng');
end.
