Write a program that reads students’ names followed by their test scores.
The program should output each student’s name followed by the test scores
and the relevant grade. It should also find and print the highest test score
and the name of the students having the highest test score.
Student data should be stored in a struct variable of type studentType,
which has four components: studentFName and studentLName of type
string, testScore of type int (testScore is between 0 and 100), and
grade of type char. Suppose that the class has 20 students. Use an array of 20
components of type studentType.
Your program must contain at least the following functions:
a. A function to read the students’ data into the array.
b. A function to assign the relevant grade to each student.
c. A function to find the highest test score.
d. A function to print the names of the students having the highest test
score.
Your program must output each student’s name in this form: last name
followed by a comma, followed by a space, followed by the first name; the
name must be left justified. Moreover, other than declaring the variables and
opening the input and output files, the function main should only be a
collection of function calls.
