Arrays are very dangerous data types for many reasons, one of which is that they don't have an at method like vectors that raises an exception if an improper index is used. write a function named "safe_at" that takes an array and an index and returns a reference to the element (at that index) in the array. the array can be of any type, and the index is a size_t. if the index is greater or equal to the size of the array, raise a std: : out_of_range exception.

input:

#include
int arr_1[] {1, 7, 9, 3, 67};
assert_eq(safe_at(arr_1, 0), 1);
assert_eq(safe_at(arr_1, 4), 67);
assert_throw(safe_at(arr_1, 5), std: : out_of_range);
assert_throw(safe_at(arr_1, -1), std: : out_of_range);
assert_eq(safe_at(arr_1, 2), 9);
