Please follow the template given below.

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 high- est test score and the name of the students having the highest test score. Student data should be stored in a struct variable oftype studentType, which has four components: student FName and studentLName of type string, test score of type int (test Score 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. const int NO_OF_STUDENTS = 20; struct studentType string student FName; string studentLName; int testScore; char grade; void getData(ifstream& inFile, studentType sList[], int listSize); void calculateGrade(studentType slist[], int listSize); int highest score(const student Type slist[], int listSize); void print Result of stream& outFile, const student Type SList[], int listSize); int main() ifstream inData; ofstream outData; student Type studentList[NO_OF_STUDENTS]; // Open input file inData.open("Ch9_EX2Data.txt"); if (!inData) cout
