C++_數組逆序輸出

僞碼： 

REVERSE(i, a, temp)//數組逆序輸出//

1.for i from 0 to 4, step (+1)

2.output a[i]                                     //正序輸出數組a[N]//

3.for i from 0 to 2, step (+1)

4.{ temp<-a[i]; a[i]<-a[4-i]; a[4-i]<-temp; }

5.for i from 0 to 4, step (+1)

6.output a[i]                                     //倒序輸出數組a[N]//

7.return

測試用例：original array:

   9   6   5   4   1

測試結果：sorted array:

   1   4   5   6   9

源程序：

#include"iostream"

#define N 5

using namespace std;

int main()

{

      int a[N]={9,6,5,4,1},i,temp;

      printf("\n original array:\n");

      for(i=0;i<N;i++)

            printf("%4d",a[i]);

      for(i=0;i<N/2;i++)

      {

            temp=a[i];

            a[i]=a[N-i-1];

            a[N-i-1]=temp;

      }

      printf("\n sorted array:\n");

      for(i=0;i<N;i++)

            printf("%4d",a[i]);

      system("pause");

      return 0;
