Sure! I can help you with that. Here's a C++ program that reads the details of ten students for a single course and computes the total marks and letter grade for each student. It also displays the student who scored the maximum marks, the maximum and minimum marks, and the details of each student in alphabetical order.
```c++
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
struct Student {
string name;
string ID;
double mid;
double final;
double total;
char grade;
};
// Function to compute the total marks for each student
void computeTotal(Student& student) {
student.total = student.mid + student.final;
}
// Function to compute the grade for each student
void computeGrade(Student& student) {
if (student.total >= 90)
student.grade = 'A';
else if (student.total >= 80)
student.grade = 'B';
else if (student.total >= 70)
student.grade = 'C';
else if (student.total >= 60)
student.grade = 'D';
else
student.grade = 'F';
}
// Function to display the details of each student in alphabetical order
void displayDetails(Student students[], int numStudents) {
// Sort the students based on their names
for (int i = 0; i < numStudents - 1; i++) {
for (int j = 0; j < numStudents - i - 1; j++) {
if (students[j].name > students[j + 1].name) {
Student temp = students[j];
students[j] = students[j + 1];
students[j + 1] = temp;
}
}
}
// Display the details of each student in a table form
cout << "----------------------------------------------------" << endl;
cout << "Name\t\tID\t\tTotal\t\tGrade" << endl;
cout << "----------------------------------------------------" << endl;
for (int i = 0; i < numStudents; i++) {
cout << setw(15) << left << students[i].name << "\t";
cout << setw(8) << left << students[i].ID << "\t";
cout << setw(8) << left << students[i].total << "\t";
cout << setw(8) << left << students[i].grade << endl;
}
cout << "----------------------------------------------------" << endl;
}
int main() {
const int numStudents = 10;
Student students[numStudents];
double maxMarks = -1;
string maxStudent;
// Read the details of each student
for (int i = 0; i < numStudents; i++) {
cout << "Enter details for student " << i + 1 << ":" << endl;
cout << "Name: ";
cin >> students[i].name;
cout << "ID: ";
cin >> students[i].ID;
cout << "Midterm Marks: ";
cin >> students[i].mid;
cout << "Final Marks: ";
cin >> students[i].final;
// Compute the total marks and grade for each student
computeTotal(students[i]);
computeGrade(students[i]);
// Check if the current student has scored the maximum marks
if (students[i].total > maxMarks) {
maxMarks = students[i].total;
maxStudent = students[i].name;
}
cout << endl;
}
// Display the maximum and minimum marks
cout << "Maximum Marks: " << maxMarks << endl;
cout << "Minimum Marks: " << students[numStudents-1].total << endl;
// Display the details of each student in alphabetical order
displayDetails(students, numStudents);
// Display the student who scored the maximum marks
cout << "Student who scored maximum marks: " << maxStudent << endl;
return 0;
}
```
Now, let's go through the program step by step:
1. We start by defining a struct called `Student` that holds the details (name, ID, midterm marks, final marks, total marks, and grade) of each student.
2. Next, we define three functions: `computeTotal` to calculate the total marks for each student, `computeGrade` to assign a grade based on the total marks, and `displayDetails` to display the student details in alphabetical order.
3. In the `main` function, we declare an array of `Student` objects called `students` with a size of `numStudents` (which is set to 10).
4. We then use a `for` loop to read the details for each student from the user, calculate the total marks and grade, and find the student who scored the maximum marks.
5. After that, we display the maximum and minimum marks.
6. We call the `displayDetails` function to display the details of each student in alphabetical order.
7. Finally, we display the name of the student who scored the maximum marks.
That's it! Compile and run the program to see the results.
