1. This question has two parts.
   1. Write an algorithm for a function to perform the following task: The algorithm calculates the average of numbers stored only in certain index positions in an integer array of size 100. The function receives an integer parameter k. Only values stored at index positions that are divisible byk (integer division) would take part in the calculation. Values stored in other index positions do not take part in the calculation. The algorithm returns the average value. The whole array may not be full, so a value called count will indicate how much of the array is full. Note that 0 <= count < 100.

1. Using the C language implement your algorithm for question 2a as a function called Average. Instead of printing to the screen, function Average takes an array as one of its parameters and returns the average of the numbers stored in the array. Note that there could be other parameters, including k. Then write an complete modular C main program that tests the use of your function.Build, run and test your program. Copy the source code of the program into your answer below.

1. This question has three parts
   1. Write an efficient C function called counter, which receives a few parameters. One of these parameters is an array of integer numbers. The array always has sorted numbers in ascending order and numbers can be duplicated. To have an efficient function, you need to make use of this fact when designing your function. This function counts the number of times the largest number appears in the array. As an example, if the array contains 2, 4, 7, 9, 9, 14, 16, the counter function will return 1, as the largest number is 16, and it only occurs once.
