   int a[1],b[1];
   a[0]=1;
   b[0]=2;
   b[1]=4;
   int *num1;
   num1 = &b[0];
   a[1]= static_cast<int>(*(num1));
   cout<<a[0]<<endl<<a[1]<<endl<<b[0]<<endl<<b[1];

   Output seems to be unpredictable as the size of arrays is 1 and the code accesses a[1] and b[1]

   #include<iostream>
   
   using namespace std;
   
   int main()
   {
       int a[1],b[1];
       a[0]=1;
       b[0]=2;
       b[1]=4;
       int *num1;
       num1 = &b[0];
       a[1]= static_cast<int>(*(num1));
          cout<<a[0]<<endl<<a[1]<<endl<<b[0]<<endl<<b[1];
     return 0;
   }
