Structures and Arrays: error code: "local function definitions are illegal"

meggoxoxo (2)
This is my next assignment.:

Write a program that reads a student's name followed by their test score. The program should output each students 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.

The 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.

The program must output each students name in this form: last name followed by a comma, followed by a space, followed by the 1st name, and 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 functions calls.

You havent close highest score function, the last } only close for statement, not the function

Okay, so after I put the missing } in, I get an error code that reads: " 'highest score' : must return value. What do I do now? What am I missing?

You're missing a return value
