Answer 1

看Unix/Linux上的man：
Standard
C
Library
Functions
gets(3C)

gets,
fgets
-
get
a
string
from
a

int
n,
FILE
*stream);
DESCRIPTION
The
gets()
function
reads
bytes
from
the
standard
input
stream
(see
intro(3)),
stdin,
into
the
array
pointed

by
s,
until
a
newline
character
is
read
or
an
end-of-file
con-
dition
is
encountered.
The
newline
character
is
discarded
and
the
string
is
terminated
with
a
null
byte.

gets是标准库函数，要求传入的是一个数组的地址。其实是要求caller应当分配空间给他。你的结构体中指针数组指向了已经分配好的内存吗？如果没有就别想了。想用就自己先给他空间
