C编程，从一个数组中的一个数组中选择元素并将其移动到另一个数组 [英] C Programming on selecting and moving elements from an array within an array to another array

问题描述

您好，我想编写一个程序来选择一个数组(V [S])中具有最多元素数(1至10)的数组(v1至v8)，并将其放在另一个数组(V_prime)中.我将一直这样做，直到数组V_prime达到最大值或从1到10的元素数被选择为止，但我不确定如何编写它.任何建议将不胜感激.

Hi, I want to write a program to choose the array(v1 to v8) with the most number of elements(1to 10) within an array(V[S]) and put it in another array(V_prime). I will do so until the array V_prime is at maximum or the number of elements from 1 to 10 are chosen but I not sure how to write it. Any advice will be appreciated.

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include<string.h>
#define S 15

int main()
{
    int V_prime[100]={0},V1[S];
    int array[S];
    int i,j;
    int points=10;      //no of elements

    int v1[S] = {1};
    int v2[S] = {5};
    int v3[S] = {2,4};
    int v4[S] = {3,4,7};
    int v5[S] = {6,9};
    int v6[S] = {5,8,9};
    int v7[S] = {6,7,10};
    int v8[S] = {10};
    int V[S] = {v1[S],v2[S],v3[S],v4[S],v5[S],v6[S],v7[S],v8[S]};
    int h1[S] = {v1[S],v2[S],v3[S]};
    int h2[S] = {v7[S],v8[S]};
    int h3[S] = {v3[S],v5[S],v6[S],v7[S]};

    for(i=0;i<S;i++)
    V1[i] = V[i];           //copy arrayV[S] to V1[S]
    for(i=0;i<points;i++)   //set array[] to have elements from 1 to points
    {   array[i] = i;
    }

推荐答案

我强烈建议您不要使用#defineS.每当使用#define时，您都需要添加括号，并且需要避免#defines很短，因为它们肯定会引起问题.

另外，为什么要为所有数组指定大小为15?也许您应该使用双端队列或媒介来解决问题?或者，您不能最初调整数组的大小，而不能使用_countof()获得大小.

例如:int v1 [] = {1};
...

对于(long j = 0; j< _countof(v1); j ++)
...

I would strongly suggest against using #define S. Whenever you use #define you need to add paranthesis and you need to avoid #defines that are very short as they certainly will cause problems.

Also, why are you specifying a size of 15 for all of the arrays? Maybe you should use a deque or vector for your problem? Alternatively you can not size the arrays initially and use _countof() to get the size.

example: int v1[] = {1};
...

for (long j=0; j<_countof(v1); j++)
...
