Your program is to use two data structures to read in student grade data, perform some calculations, sort the students in ascending order by average, determine some class statistics, and output the results. The first data structure is classStatsand should have variables mean (float), min (float), max (float), median (float), and name (character pointer). You will need to create this structure yourself, placing it above main() in hwk1.cpp and create one variable of type classStats (not a pointer) in your main program. !The second data structure is called student and will have variables first (character pointer), last (character pointer), exam1 (integer), exam2 (integer), exam3 (integer), and mean (float). This structure is in the file student. h. Take a moment to study this structure to understand it before using it. You will need to create an array of 19 studentpointers and will need to allocate space for each in your main program using malloc(). !The data file contains the name of the course followed by 19 students, each student having three exam grades. Use the array of student pointers to store the information as read in using scanf. An example data file is below:
