问题标题: 盘点鬼畜输出helloworld做法！！！

1、输出自定义类

#include <iostream>
using namespace std;

class MyData
{
public:
	string a, b, c;
public:
	MyData(string a, string b, string c) : a(a), b(b), c(c) {};
};

ostream& operator << (ostream& os, const MyData& my_data)
{
	os << my_data.a << " " << my_data.b << " " << my_data.c;
	return os;
}

int main()
{
	MyData Hbh("Hello", ",", "world!");
	cout << Hbh << endl;
	return 0;
}

2、超级鬼畜！！！

#include <iostream>

using namespace std;

string f(int seed) {

ﾠ ﾠ srand(seed);

ﾠ ﾠ string s;

ﾠ ﾠ while (true) {

ﾠ ﾠ ﾠ ﾠ int n = rand() % 20;

ﾠ ﾠ ﾠ ﾠ if (n == 15) break;

ﾠ ﾠ ﾠ ﾠ s.push_back((char) (n + 100));

ﾠ ﾠ }

ﾠ ﾠ return s;

}

int main() {

ﾠ ﾠ cout << f(41488932) + " " + f(24081743);

ﾠ ﾠ return 0;

}

3、宏YYDS！

#include <stdio.h>
#define Say(sth) puts(#sth)
int main(){
    return Say(Hello world!);
}

4、断章取义！！！

#include <stdio.h>
int main(){
    return puts(&”Do not say: Hello world!”[12]);
}

5、话分两头的helloworld

#include <iostream>
// 本文转自 C++Builder研究 – http://www.ccrun.com/article.asp?i=999&d=v433i2
class say
{
public:
say()
{
std::cout << "Hell";
}
~say()
{
std::cout <<"world!";
}
}hello;
int main()
{
std::cout << "o ";
return 0;
}

6、罕见做法

#include <iostream>
template <char * words>
class say
{
public:
void operator () ()
{
std::cout << words;
}
};
extern char hello[] = ”Hello world!”;
int main()
{
return say<hello>()(), 0;
}

7、外星人语言！

#include <stdio.h>
void alien_say(char * p){
    while (putchar(*(p += *(p + 1) – *p)));
}
int main(){
    return alien_say(“BETHO! Altec oh liryom(a loadjudas!) dowd.”), 0;
}
