I am having troubles on how to do this, can somebody help with step by step?

You are given the following function named fillRandom: void fillRandom (int x[], int size) { int i; for(i = 0; i #include #include /* list all prototype */ int main(void) /* start here *1 return 0; } Your task is to complete above function and call it from the main int the following order: 1. Print element of array grades after calling fillArray function. 2. Print the average of numbers after calling getAverage function. 3. Print the largest element of the array grades after calling getlargest function. 4. Print the middle number after calling getMiddle function
