Question 4- Easy Array Input: Write a program that allows the user to input as many integers as they want, separated by a space, until they press enter. The program should create an array with the same number of elements as they input and fill the array with the values input. It should output how many integers the user input, and the values that were input. For example if the user inputs: 23 -43 54 6 999 78 and then presses enter, the program should output 6 and then output 23 -43 54 6 999 78. Assume that at least one integer must be entered. If you use a fixed number of elements, you will lose 5 points.
