C++同过数组传递后改变数组的元素

#include "Program.h"
#include "ArrayTest.h"
#include "Common.h"

void ChangeDatasByRef(int &m,int &n);
int main()
{
  int datas[10]={10,1,2,3,4,5,6,7,8,9};
  ChangeArray(datas);
  cout<<"After Changed the Array"<<endl;
  //int len=GetMyArrayLen(datas);
  int len=GetArrayLen(datas);
  //int len=10;

  for (int i=0;i<len;i++)
  {
   cout<<datas[i]<<" ";
  }
  cout<<endl;

   int result;
  cin>>result;
  return 0;
}
