Question:Which of the following statement is correct about the program given below? #include<iostream.h> int main() { int arr[] = {1, 2 ,3, 4, 5}; int &zarr = arr; for(int i = 0; i <= 4; i++) { arr[i] += arr[i]; } for(i = 0; i <= 4; i++) cout<< zarr[i]; return 0; }

1.The program will print the output 1 2 3 4 5.

2. The program will print the output 2 4 6 8 10.
