Question

1. Consider the following program that reads a number of nonnegative integers into an array and prints the contents of the array.   Complete the missing parts, add new function prototypes and function definitions, and test the program several times.

Add the following to the program:

1. Write a void function that prints the list of nonnegative integers in reverse.

2. Write a void function that prints all the numbers stored in the list that are greater than 10. It will also print the number of such numbers found.

3. Write a function that determines the largest value stored in the array and returns that value.

4. Write a function that determines the smallest values stored in the array and returns that value.

5. Write the function calls with the appropriate arguments in the function main.

6. Write appropriate comments for each function similar to the ones provided.
