Question

Write down this following program using 'C' language programming.

At Unknown University, Admissions department has discovered that best applicants usually go to big-name schools instead and the worst often do badly in courses, so school wants to concentrate recruitment efforts and economic aid resources on middle half of the applicants. You must write a program that takes a file containing a list of applicants, in which every applicant has a name and a total SAT score, and prints an alphabetical list of the middle half of these applicants. (Eliminate the best quarter and the worst quarter, and then alphabetize the rest). This could be done using a simple iterative technique. First, read data from a file named apply.txt into an array of structures (let N be the total number of applicants). This starts a loop that eliminates applicants one at a time, until only half are left. Within this loop, let first be a pointer to first array element that is still included, last be a pointer to the last one and r (the number of remaining) be initialized to N. Each time around the loop, either first is incremented or last is decremented and r decreases by-

1. At each step,

a) if r is even, find the remaining applicant with the lowest SAT score and swap it with the applicant at first. Then increment first, decrement r, and repeat.a

b) if r is odd, find remaining applicant with the highest SAT score and swap it with the applicant at last. Then decrement last and r and repeat.

c) Quit when r <= N/2. Return values of first and r.
When only half applicants are left, use any sort technique to sort them alphabetically. Write down the sorted list to a user-specified output file.
