a. Define an array with a maximum of 20 integer values and fill the array with numbers input from the keyboard or assigned by the program. Write a function named split() that reads the array and places all zeros or positive numbers in an array named positive and all negative numbers in an array named negative. Finally, have your program call a void return-type function named displayArray) that displays the values in both the positive and negative arrays. This means your program must invoke the displayArray) function twice, once to display the positive array and once to display the negative array. Remember to declare your displayArray) function with a function prototype
