    Post Explain this code to me in English

    #include <iostream>
    using namespace std;
    int main()
      int a[]={1,2,3,4};
      int *arr[5]={a,a+1,a+2,a+3,a+4};
      int *p=a+4;
      return 0;
    I was solving the programming question when I encountered this.
    My answer to this code was a printed garbage value. But, turns out the answer is 2.

    *arr[1] will give you 2, since p points after the last element of a, p[2-5] will give you p[-3]. This gives you 2 also.
