Implement the functions prototyped in MyStack.h in a file named MyStack.c. Write a program (Student.c will have your main method for execution) that uses your stack to read student records (Student.h) from standard in and stops when a blank line is entered. Your program should then calculate and output the min, max, and average student grade.

For example,

$ Students

John 15

Tim 15

Sarah 20

Chris 10

min: 10

max: 20

average: 15
