Write a QBasic program to sort aphetically the number of student names, each student name has first and last name like "Ahmed Yousef". The program should print the names before and after sorting. Also, the program should use "eod" as the last record in the file. The program should consider the upper and lower case for the names. 1. The first sorting should be based on the first name "Ahmed". Note that, the first names of two students may have the same first character and in this case, the sorting should be considered based on the second character of the first names of two students. 2. The second sorting should be based on the last name "Yousef". Note that, the last names of two students may have the same first character and in this case, the sorting should be considered based on the second character of the last names of two students
