Pointer Arithmetic in C++ - 4 (CAN BE ASKED IN INTERVIEW)

 #include<iostream>

using namespace std;

int main(){

    // int a = 5;

    int arr[20] = {1, 2, 3, 4, 5, 6};

    int *ptr1 = arr; //

    int *ptr2 = ptr1 + 3; //4

    cout << (ptr2 == arr) << endl;

// yes : true : 1 (ptr1 == arr) OUTPUT- 1 (yes points

to same memory location)

    // cout << ptr2 - ptr1 << endl;

    return 0;

}

OUTPUT-

0
