the answer will be 9 int main() { array<int,5>arr={0,2,1,3,5}; int *x; // declaration of a pointer x... x=&arr[3]; //pointer x is pointed to arr[3] therefore the value of *x becomes 3 ( *x=3) *x+=5; // *x=*x+5=8 ..... as pointer x is pointing to arr[3] with & operator as value of *x changes value of arr[3] also changes ... so now arr[3]=8... cout<<arr[3]+arr[2]; // 8+1 = 9 return 0; }

The code has some errors: 0) x*+=5 is an invalid operation. It should be *x+=5. 1) x[3] points to arr+6, which is an invalid location and has no data at all. So it will return a random value. So maybe the challenge was wrong? Just mark it with a wrong answer.

@DT That was x[3] + x[2], which you replaced with arr[3] + arr[2], and thats what corrected the code. But I don't know what was in the challenge though.
