//将数组逆序存放，函数inv中的Shape referencebePointer variable

#include "stdafx.h"

printf("the original array:\n");
for(i=0; i<10; i++)
printf("%d",a);

printf("the array has been inverted:\n");
for(i=0; i<10; i++)
printf("%d",a);
printf("\n");

}
void inv(int *x,int n) // pointer point of the pointer parameter x pointer variable
{int *p,temp,*i,*j,m=(n-1)/2;
i=x; j=x+n-1; p=x+m;
for(; i<=p; i++,j--)
{temp=*i; *i=*j; *j=temp; } //*i and *J swap
