#include <unistd.h>

void func(int sig)

	signal(sig, func);
	if(sig==SIGINT)
		cout << "我不怕^C!" << endl;
	else if(sig==SIGTERM)
		cout << "kill没用!" << endl;
	else
		cout << "(impossible)" << endl;
}
int main()
{
	signal(SIGINT, func);
	signal(SIGTERM, func);
	for(;;){
		cout << ".zZ" << flush;
		sleep(10);
