1. (3 points)
Define a struct, named FullName, that contains the following fields:
lastname - a string
firstname - a string
midInitial - a char
2. (4 points)
Define a struct, named Student, that contains the following fields:
name - a FullName (the structure from section a)
tests - an array for storing 3 floats
average - a float
lettergrade - a char
3. (2 points)
In a main() function, declare a variable, named roster, that is an array (size 24) of your new Student structure type.
4. (2 points)
Write a function with the following prototype:
float DetermineAverage(const float[3]);
The function should accept an array of 3 floats as a parameter and then should return the average of the three numbers.
5. (2 points)
Write a function with the following prototype:
char DetermineLetterGrade(float);
The function should accept a float(test grade) as a parameter and should return the corresponding letter grade based on the following grading scale:
90% - 100%: A
80% - 89%: B
70% - 79%: C
60% - 69%: D
Below 60%: F
6. (6 points)
Write a function with the following prototype:
Student GetData();
The function will prompt the user to enter her/his name and three test scores. In the function, call DetermineAverage() to find the Student
