Solution

#include<iostream>
#include<chrono>
using namespace std;
using namespace std::chrone;
void main(){
   int i,loop, ary[1000]={}
   int *parray; // declaring pointer
   parray=ary;
  
   double sum=0.0;
   _int64 duration;
   high resolution clock::time point t1,t2;
   t1 = high resolution clock::now();
   for(i=0;i<1000;i++)
   ary[i]=1;
   // changed code
   parray=1;
   //
   for(loop=0;loop<500000;loop+){
       for(i=0;i<1000;i++)
       sum+=*(parray+i);// here is changed code
       //sum +=ary[i];
   }
   cout<< \"sum=\"<<sum<<endl;
   t2=high resolution clock::now();
   duration = std::chrono::duration_cast<<std::chrono::microseconds>(t2-t1).count();
   cout<<duration<<endl<<endl;
