C++实现将数组中的值反转

#include <iostream>
using namespace std;
 
int* reverse(int* list, int size)
{
 for (int i = 0, j = size - 1; i < j; i++, j--)
 {
  // Swap list[i] with list[j]
  int temp = list[j];
  list[j] = list[i];
  list[i] = temp;
 }
 
 return list;
}
 
void printArray(int* const list, int size)
{
 for (int i = 0; i < size; i++)
  cout << list[i] << " ";
}
 
int main()
{
 int list[] = {1, 2, 3, 4, 5, 6};
 int* p = reverse(list, 6);
 printArray(p, 6);
 
 return 0;
}

#include<math.h>
int main(void)
{
  char c[100][100];
  int i=0,j;
  char a;
  while (1)
  {
    scanf("%s%c",c[i],&a);
    if (a=='\n')
    {
      break;
    }
    i++;
  }
  for (j=i; j>=0; j--) {
    printf("%s ",c[j]);
  }
  return 0;
}
