Write a function, insertat, that takes four parameters: an array of integers, the number of elements in the array, an integer (say, insertitem), and an integer (say, index). the function should insert insertitem in the array provided at the position specified by index. if index is out of range, output the following: position of the item to be inserted is out of range or if the index is negative: position of the item to be inserted must be nonnegative (note that index must be between 0 and the number of elements in the array; that is, 0 < = index < the number of elements in the array.) assume that the array is unsorted.

Implemented the program using C++ below

Explanation:
