Write a program that dynamically allocates an array of integers. The size of the array (the number of integers, not the byte size) should be read from the user using scanf(). You may assume that the user will input a positive integer (i. e., don't do error checking). The elements of the array should be filled using random() function. After filling the array with random numbers, your program should then make a copy of the array, and sort the new array in ascending order: that is, the first entry of the array should contain the smallest integer in the array, while the last entry should contain the largest integer in the array. Then make a second copy of the original array, and sort it in descending order. Finally your program should print out all three arrays. All three arrays should be separately allocated using malloc() library function. Don't forget to call free() to deallocate the arrays.
