Question

My teacher wants it in this format: (How would  I change my program to fit her layout?)

Function definition

I have this what I have:

#include <string>
#include <iostream>
using namespace std;

// 1.
struct FullName{
    string lastname;
    string firstname;
    char midInitial;
};

// 2.
struct Student{
    FullName name;
    float tests[3];
    float average;
    char lettergrade;
};

// 4.
float DetermineAverage(const float tests[3]){
    float avg = 0;
    
    for (int i = 0; i < 3; i++)
        avg += tests[i]/3;
    
    return avg;
}

// 5.
char DetermineLetterGrade(float grade){
    char lettergrade;
    
    if (grade >= 90)
        lettergrade = 'A';
    else if (grade >= 80)
        lettergrade = 'B';
    else if (grade >= 70)
        lettergrade = 'C';
    else if (grade >= 60)
        lettergrade = 'D';
    else
        lettergrade = 'F';
    
    return lettergrade;
}

// 6.
Student GetData(){
    Student s;
    
    // get name    
    cout << "Enter first name: " << endl;
    cin >> s.name.firstname;
    cout << "Enter middle initial: " << endl;
    cin >> s.name.midInitial;
    cout << "Enter last name: " << endl;
    cin >> s.name.lastname;
    
    // three test scores
    for (int i = 0; i < 3; i++){
        cout << "Enter test score #" << (i+1) << ": " << endl;
        cin >> s.tests[i];
    }
    
    // find average and lettergrade
    s.average = DetermineAverage(s.tests);
    s.lettergrade = DetermineLetterGrade(s.average);
    
    return s;
}

// 7.
void PrintStudent(const Student s){
    cout << "Student Name:   " << s.name.firstname << " "
         << s.name.midInitial << ". " << s.name.lastname << endl;
    cout << "Test 1:         " << s.tests[0] << endl;
    cout << "Test 2:         " << s.tests[1] << endl;
    cout << "Test 3:         " << s.tests[2] << endl;
    cout << "Average:        " << s.average << endl;
    cout << "Final Grade:    " << s.lettergrade << endl;
}

int main() {
    // 3.
    Student roster[24];
    
    // 8.
    roster[23] = GetData();
    cout << endl;
    PrintStudent(roster[23]);
    
    return 0;
}

Explanation / Answer

#include <string>
#include <iostream>
using namespace std;

// 1.
struct FullName{
string lastname;
string firstname;
char midInitial;
};

// 2.
struct Student{
FullName name;
float tests[3];
float average;
char lettergrade;
};

// 4.
float DetermineAverage(const float tests[3]);//Function Prototype here

// 5.
char DetermineLetterGrade(float grade);//Function Prototype here

// 6.
Student GetData();//Function Prototype here

// 7.
void PrintStudent(const Student s);//Function Prototype here

int main() {
// 3.
Student roster[24];

// 8.
roster[23] = GetData();
cout << endl;
PrintStudent(roster[23]);

return 0;
}

//Function definition here

float DetermineAverage(const float tests[3]){
float avg = 0;

for (int i = 0; i < 3; i++)
avg += tests[i]/3;

return avg;
}

//Function definition here

char DetermineLetterGrade(float grade){
char lettergrade;

if (grade >= 90)
lettergrade = 'A';
else if (grade >= 80)
lettergrade = 'B';
else if (grade >= 70)
lettergrade = 'C';
else if (grade >= 60)
lettergrade = 'D';
else
lettergrade = 'F';

return lettergrade;
}

//Function definition here

Student GetData(){
Student s;

// get name
cout << "Enter first name: " << endl;
cin >> s.name.firstname;
cout << "Enter middle initial: " << endl;
cin >> s.name.midInitial;
cout << "Enter last name: " << endl;
cin >> s.name.lastname;

// three test scores
for (int i = 0; i < 3; i++){
cout << "Enter test score #" << (i+1) << ": " << endl;
cin >> s.tests[i];
}

// find average and lettergrade
s.average = DetermineAverage(s.tests);
s.lettergrade = DetermineLetterGrade(s.average);

return s;
}

//Function definition here

void PrintStudent(const Student s){
cout << "Student Name: " << s.name.firstname << " "
<< s.name.midInitial << ". " << s.name.lastname << endl;
cout << "Test 1: " << s.tests[0] << endl;
cout << "Test 2: " << s.tests[1] << endl;
cout << "Test 3: " << s.tests[2] << endl;
cout << "Average: " << s.average << endl;
cout << "Final Grade: " << s.lettergrade << endl;
}
