函数

goto

int main()
{
	printf("nice ");
	goto again;
	printf("t0 ");
again:
	printf("meet youn");
	return 0;
}
int main()
{
again:
	printf("寸心n");
	goto again;
	return 0;
}

for (.,.)
{
	for (...)
	{
		for (...)
			if (disaster)
				goto error;
	}
}
error:
	if(disaster)
		....//处理错误情况

memset

int main()
{
	char a1[] = "hello world!";
	memset(a1,'*',5);
	printf("%s", a1);
	return 0;
}

printf

int main()
{
	printf("%d", printf("%d", printf("%d", 43)));
	return 0;
}

结果：4321
printf返回值是打印在屏幕上的字符个数

strcpy

int main()
{
	char a1[]="##########";
	//         nice####
	// ''为字符串结束标志，后面的#..#就不打印了
	char a2[] = "nice";
	strcpy(a1, a2);//拷贝''
	printf("a1=%s", a1);
	return 0;
}

数组

int main()
{
	int a[] = { 0,1,2,3,4,5 };
	printf("%pn", a);
	printf("%pn", a+1);
	printf("%pn", &a);
	printf("%pn", &a+1);
	printf("%pn", &a[0]);
	printf("%pn", &a[0]+1);
	return 0;
}
