首先声明，本人学习极菜，可能问的问题很幼稚，高手不要见笑哈

cs2104s
1）tut4,q1:
what is the type of x if x is declared as:
int *(*(*x)[6])();
really blur for it, even dun know it's a function or variable


cs2105
2)TUTORIAL上讲什么ODD， EVEN FUNCTION
什么关于ODD的或者EVEN的那个FOURIER SERIES 的An 或者Bn其中一个就为0，不太明白，哪位指点一二？


cs3223
3）if using B+ tree index on a file, given a search key to retrieve a record, when need make a disk I/O?

4)cs3240是不是学一些GUI的规则，然后考试去判断实例啊
第6周了，连具体学什么都不太清楚，见笑了
考试的题目是什么样子啊，可否随便出一个，让我有一个感官认识

com3

this function takes no argument and returns a pointer to integers.


2. odd function: f(-x) = -f(x)
even function: f(-x) = f(x)

you can observe that cos function is even, and sin is odd. that gives you some intuitive idea(not a rigid proof) on the matter.
think cs2105 doesn't require more than this liao.
