C Programming Language Task: Deviation Write a program that prompts the user to enter N numbers and calculates which of the numbers has the largest deviation from the average of all numbers. You program should first prompt the user to enter how many numbers that will specify. The program should then scan for each number, separated by a newline. You should calculate the average value and return the number from the list which is furthest away from this average (to 2dp). Try using dynamic memory functions to store the incoming array of numbers on the heap. Code to build from: + 1 #include 2 #include 3 4 int main(void) { 5 6} 7 Output Example: deviation.c How many numbers? 5 Enter them: 1.0 2.0 6.0 3.0 4.0 Average: 3.20 Largest deviation from average: 6.00
