关于printf，请大家看看

printf(&unix["\021%six\012\0"],(unix)["have"] + "fun" - 0x60)

高人分析结果看看

我们知道，设char a[N];则a实际上是取a+i地址所指的内容；
在linux下，unix是宏，其值为1；
首先看&unix["\021%six\012\0"]，
等于取1+"\021%six\012\0"的地址即"%six\012\0"，
\012是\n，\0是字符串的结束符，所以打印的format是"%six\n"，其中%s表示要打印字符串；
同样，再看(unix)["hava"]，是要取1+"hava"地址的单个字符，即'h'后面的'a'；而'a'=0x61；
所以(unix)["have"] + "fun" - 0x60等于"fun"+0x61-0x60等于"fun"+1等于"un"；
因此，源语句是printf("%six\n","un";
输出结果是unix

是真的，分析的很有道理

这个题目是不是学校用来考试的？

four calling birds, three french hens, two turtle doves
and a partridge in a pear tree.

On the tenth day of Christmas my true love gave to me
ten lords a-leaping,
nine ladies dancing, eight maids a-milking, seven swans a-swimming,
six geese a-laying, five gold rings;
four calling birds, three french hens, two turtle doves
and a partridge in a pear tree.

On the eleventh day of Christmas my true love gave to me
eleven pipers piping, ten lords a-leaping,
nine ladies dancing, eight maids a-milking, seven swans a-swimming,
six geese a-laying, five gold rings;
four calling birds, three french hens, two turtle doves
and a partridge in a pear tree.
