Design an Algorithm for the Chosen Solution

One of the jobs that Joe Roberts has been given at work is to order special paper for a report for a board meeting. The paper comes in reams of 500 sheets. He always makes five more copies than the number of people that will be there. Joe wants to know how many reams of paper he needs for a meeting. He can order only whole, not partial, reams. Assume the required number of pages will not equal an exact number of reams. Test your solution with the following data: The report is 140 pages long. There will be 25 people at the meeting. Construct the Input-Processing-Output (I.P.O.) Chart for the chosen solution. Design an algorithm for the chosen solution. Draw the flowchart for the chosen solution

Write a function in C to calculate the F-score of of a Given Array

The F-score of an array of integers is calculated as follows:

For each integer in the array, the F-score is 2 if the last digit or the second-last digit of the integer is divisible by 4, or 3 if both the last and second-last digits are divisible by 4, and 0 if none of those digits are divisible by for.

Here second-last digit means the digit in the tens place.
The F-score is never more than 3.
For example: 138 scores 2, 142 scores 2, 32148 scores 3, and 17322 scores 0.
The total F-score of an array is simply the sum of the F-scores of all the integers in the array.
For example: the array {138, 142, 32148, 17322} will score 2+2+3+0 = 7.
If an integer does not have a second-last digit, it is assumed to be 0 (which is divisible by 4).

Write a function in C which calculates the F-score of of a given array. The prototype of the function should be as follows:

int array_score(int a[], int len);
