Write c++ program that reads 100 students information from a text file (stud.txt) into parallel arrays. Then find the following (use functions for each requirement);

1. maximum mark and student name that get this mark.

2. overall class average

3. number of students that holds grade letter B+, A-, A.

use the following function prototypes:

1. void max(string names[], float marks [], int size []);

2. float average (float marks[], int size[]);

3. in count (char grade[], int size[]);
