C :

#include<stdio.h>

int main()
{
	char a;
	scanf("%c",&a);
	if(a>='a'&&a<='z'){
		printf("xiaoxiezimu");
	}
	if(a>='A'&&a<='Z'){
		printf("daxiezimu");
	}
    if(a<'A'||(a>'Z'&&a<'a')||a>'z'){
		printf("bushizimu");
	}
	return 0;
}

C++ :

#include <iostream>
#include <cstdio>
using namespace std;
int main()
{
    char c;
    cin>>c;
    if(c>='a' && c<='z')
    {
        cout<<"xiaoxiezimu"<<endl;
    }
    else if( c>='A' && c <='Z')
    {
        cout<<"daxiezimu"<<endl;
    }
    else
    {
        cout<<"bushizimu"<<endl;
    }
    return 0;
}
