Write a program to do the following. In main function, the program should define an integer array and a pointer that points to the array. it
will ask the user to input 25 students' scores (scores are between 0 and 100 inclusive, so need to do
input validation), then pass the pointer and its size to a function. The function should find the
corresponding letter grades and return the pointer that points to the array of letter grades.
Also pass the score pointer and its size to the other function, which will calculate the average of those
25 scores with the lowest and highest score dropped, and then return the average (double type).
The input of those scores and output of the letter scores and average must be in main function, and
there is no input and output in the functions besides main function.
No global variables are allowed.
90-100 (include 90 and 100) is A
80-90 (include 80 but not include 90) is B
70-80 (include 70 but not include 80) is C
60-70 (include 60 but not include 70) is D
below 60 is F

This assignment continues work on the online booking facility introduced at the end of chapter- 10. the work will be continued in the assignments for chapters 14 and 15 (a) assume that you will produce your online booking facility using an agile approach. i. suggest the kind of user research you would like to conduct for your product before iteration cycles begin. ii prioritize the requirements for your product according to business value, i.e which requirements are likely to provide the greatest business benefit, and sketch out the ux design work you would expect to undertake during the first four iteration cycles, i.e. cycle 0, and cycles 1 to 3. (b) using one of the mockup tools introduced above, generate a mockup of your product's landing page, as developed in the assignment for chapter-11 (c) using one of the patterns websites listed previously, identify suitable interaction patterns for elements of your product, and develop a software-based prototype that incorporates all the feedback and the results of the user experience mapping achieved at the end of chapter-11. if you do not have experience in using any of these, create a few html web pages to represent the basic structure of your website
