请帮助一个功能 - 请 [英] help with a funcition-please
问题描述
嗨我需要写一个名为install的函数，它需要作为参数
1- a vector
2-a number
3 - 一个名为next_level的列表
所以它会变得有点奇怪：
next_level是一个包含{vectors，with
指针}，由以下结构定义
typedef struct wnode {
int weight [maxrank + 1];
struct wnode * next;
} WEIGHTPTR，* WEIGHTPTR;
现在install是一个返回指向frist向量的指针的函数
在列表中，任何人都可以给代码定义这个功能。？
谢谢：

Okey doke。
1- a vector
你需要一个结构（用于n维向量）：
struct vector {
int direction [n];
int magnitude;
}
2-a number
int将起作用;长或短可能更合适，但我不能在没有更多信息的情况下知道
。
3 - 名为next_level
什么样的清单？所有编程教科书都有链接列表的代码;
我唯一可以从经验中推荐的是理查德释放的C
Heathfield，Lawrence Kirby和其他一些人。
所以它会变得有点奇怪：
next_level是一个包含{vectors，with
pointers}元素的列表，由以下struct
typedef struct wnode {
int weight [maxrank + 1];
struct wnode * next;
} WEIGHTPTR，* WEIGHTPTR;
我看到一个指针，但我不确定你是如何在
中代表一个向量的;我怀疑+1允许幅度，以及maxrank
指示。
现在安装是一个函数，返回指向frist矢量的指针
列表，任何人都可以给代码定义这个功能。？
Nope。当你有一个可编辑的例子时我们会帮助你，但是直到
然后我们不会为你做功课。不过我会给你一个提示：
双联系列表可以帮到你。

我的向量是通过
定义的。
int vector [n]
n昏暗的向量

好的，我有整个程序正常工作，但它是相当数量的代码，
有一些真正只能和人共处的东西，所以我会发布
我对定义安装函数的猜测
WEIGHTPTR install（int * v，int rank，WEIGHTPTR next_level）{
++ next_level.next;
返回next_level;
}
请参阅上一篇文章defn of struct WEIGHTPTR，

Hi i need to write a funcition called install, its takes as arguments
1- a vector
2-a number
3-a list called next_level
so heres where it get kinda weird:
next_level is a list comprising of elements that are { vectors, with
pointers}, defined by the following struct
typedef struct wnode {
int weight[maxrank+1];
struct wnode *next;
} WEIGHTPTR,*WEIGHTPTR;
Now install is a funcition that returns a pointer to the frist vector
in the list, Can anyone give the code to define this funcition.?
Thanks:

1- a vector
You''ll need a struct (for an n-dimensional vector):
struct vector {
int direction[n];
int magnitude;
}
2-a number
int will work; long or short may be more appropriate, but I can''t
know without more information.
3-a list called next_level
What kind of list? All programming textbooks have code for linked lists;
the only one I can recommend from experience is C Unleashed by Richard
Heathfield, Lawrence Kirby, and a few others guys.

I see a pointer, but I''m not sure how you are representing a vector in
that; I suspect that the +1 allows for magnitude, as well as maxrank
directions.
Now install is a funcition that returns a pointer to the frist vector
in the list, Can anyone give the code to define this funcition.?
Nope. We''ll help you out when you''ve got a compilable example, but until
then we won''t do your homework for you. I''ll give you a hint, though:
Double-linked lists will help you.

My vectors are defined via
int vector[n]
n dim vector

Ok i have the whole program working, but it is a fair amount of code,
with somestange stuff that really only cofuses people, so i will post
my guess for defining the install func
WEIGHTPTR install ( int *v , int rank , WEIGHTPTR next_level ){
++next_level.next;
return next_level;
}
see previous post for defn of struct WEIGHTPTR,
