阅读下面程序: include void fun1(char a,char b) { char c; c=a;a=b;b=c; } void f

阅读下面程序:

include<iostream.h>

void fun1(char a,char b)

{

char c;

c=a;a=b;b=c;

}

void fun2(char&a,char&b)

{

char c;

c=a;a=b;b=c;

}

void main()

{

char a,b;

a='x';b='y';

fun1(a,b);cout<<a<<b;

a='x';b='y';

fun2(a,b);cout<<a<<b;

}

则该程序的输出为______。
