Lab 1.1: Element Shifter Write a function that accepts an int array and the array's size as arguments. The function should create a new way that is one element larger than the argument array: The function should copy the contents of the argument array to the new array and initialize the unused elements of the second array with The function should retum a pointer to the new array Homework 1.1: Mode Function In statistics, the mode of a set of values is the value that our most often or with the greatest frequency Write a function that access arguments the following: 1. An array of integers 2. An integer that indicates the number of elements in the array The function should determine the mode of the array. That is, it should determine which value in the way occurs most often. The mode is the value the function should retum. If the array has no mode (none of the values occur more than once the function should retum-1|| Demonstrate your pointer prowess by using pointer notation instead of array notation in this function, and write a driver program to testit Input validation: Make sure that the array contains no negative values
