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);

this would start to sound a little like mortal combat

i would first let him be aware that a cover letter is official and confidential and it requires a proper formatting so that the employer doesn't have hard time when going through it. he should write it in paragraphs of about two to four sentences and use proper grammar a , spelling and proper punctuation. i will also advice him not to be emotional and not also to use images.then base his attention to the details of the job described and not other things. that is he be specific to the responsibilities and to the employers requirements. on this he should make sure that the letter reflects how good he is for the requirements detailed by the employer

the letter should not be too long nor too short.
