阅读下面程序: include void funl(char a,char b) { char c; c=a;a=b;b=C; } void f 阅读下面程序:include<iostream.h>void funl(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 fun3(char a,char b){char c;c=a;a=b;b=C;}void main(){char a,b;a='A';b='B';funl(a,b);cout<<a<<b;a='A';b='B';fun2(a,b);cout<<a<<b;a='A';b='B';fun3(a,b);cout<<a<<b;}则该程序的输出为【 】。

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

阅读下面程序:

include<iostream.h>

void funl(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 fun3(char &a,char &b)

{

char c;

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

}

void main()

{

char a,b;

a='A';b='B';

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

a='A';b='B';

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

a='A';b='B';

fun3(a,b);cout<<a<<b;

}

则该程序的输出为【 】。
