c++ - c++ 生成垂直二维数组

Question

c++ 垂直数组如何在垂直列表中创建输出。

我尝试了很多次，但它不能工作。我运行它时如何打印出来？我无法测试它，因为我不知道如何打印出来：/但我觉得我还是错了。示例输出应该是这样的

#include <iostream>

编辑

 do
{
    cout<<"Enter how many times";
    cin>>SIZE;

    cout<<"Enter Number Please: ";
     ioResult = scanf("%d", pFill);
    if (ioResult == 1)
    {
        pFill++;
        readCnt++;
    }
} while (ioResult == 1 && readCnt < arySize);

这个2怎么样

 int ary[SIZE];
int sary[SIZE];

编辑：我的答案是纯 C。如果你想做 C++，我建议你使用std::vector和std::sort

试试下面的代码。

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define SIZE 5


void getData (int*);
void printData (int*, int*);
int compare(const void*,const void*);

int main (void)
{
  int array[SIZE];
  int sorted_array[SIZE];

  getData (array);
  memcpy(sorted_array, array, SIZE*sizeof(int));
  qsort(sorted_array, SIZE, sizeof(int), &compare);
  printData (array, sorted_array);

  return 0;
}


void getData (int* pAry)
{
  int ioResult;
  int readCnt = 0;
  int* pFill = pAry;

  do
  {
    printf("Enter Number Please: ");
    ioResult = scanf("%d", pFill);
    if (ioResult == 1)
    {
      pFill++;
      readCnt++;
    }
  } while (ioResult == 1 && readCnt < SIZE);
}

int compare(const void* pa,const void* pb)
{
  int a = *(int*)pa;
  int b = *(int*)pb;

  if (a < b) return -1;
  if (a > b) return 1;
  return 0;
}

void printData (int* pAry, int* pSAry)
{
  int i=0;
  printf("\n+--------------------------------+\n");
  printf("| Original | Ascending|Descending|\n");
  printf("+----------+----------+----------+\n");

  for (; i<SIZE; i++)
  {
    printf("|%10d|%10d|%10d|\n",pAry[i],pSAry[i],pSAry[SIZE-1-i]);
  }
  printf("+--------------------------------+\n");
}

输出 12,15,14,5,8 ：

+--------------------------------+
| Original | Ascending|Descending|
+----------+----------+----------+
|        12|         5|        15|
|        15|         8|        14|
|        14|        12|        12|
|         5|        14|         8|
|         8|        15|         5|
+--------------------------------+
