C++ Student Grade Tracker Project with code source

Certainly! A Student Grade Tracker program in C++ is a practical project for managing and calculating student grades. This program allows users to input student names and their corresponding grades for various subjects. It calculates averages, identifies top-performing students, and provides a convenient way to monitor academic progress. Below are detailed steps and a simplified code example for a Student Grade Tracker in C++

Student Grade Tracker Project Using C++

Objective: The objective of the Student Grade Tracker project is to create a program that helps teachers or students keep track of grades for multiple students and subjects.
Features:
1. Add and manage student records with names and grades.
2. Calculate and display individual student averages.
3. Calculate and display class averages for each subject.
4. Identify top-performing students based on their average grades.

Steps to Create the Student Grade Tracker Project

1. Define Data Structure: Create a struct to represent a student's record, including their name and a vector to store grades.
2. Create Functions: Write functions to calculate the average grade for a student.
3. Main Menu: Implement a menu-driven interface with options to add students, calculate averages, list top performers, and quit.
4. Add Students: Allow users to input student names and grades interactively.
5. Calculate Averages: Calculate and display individual student averages.
6. List Top Performers: Sort students based on average grades and list the top-performing students.
7. Quit: Provide an option to exit the program.
8. Compile and Run: Compile the C++ code and run the program to start tracking student grades.
9. Test and Enhance: Test the program with various student records and consider adding features like grade categories, error handling, or saving data to a file for future use.

Code Example of Student Grade Tracker in C++

Here's a simplified code example for a Student Grade Tracker program:

#include 
#include 
#include 
#include 
#include 

using namespace std;

// Structure to represent a student's record
struct Student {
    string name;
    vector grades;
};

// Function to calculate the average grade for a student
double calculateAverage(const vector& grades) {
    if (grades.empty()) return 0.0;
    
    int sum = 0;
    for (int grade : grades) {
        sum += grade;
    }
    
    return static_cast(sum) / grades.size();
}

int main() {
    vector students; // Store student records

            getline(cin, student.name);

            cout << "Enter grades for " << student.name << " (enter -1 to finish): ";
            int grade;
            while (cin >> grade && grade != -1) {
                student.grades.push_back(grade);
            }

            students.push_back(student);
        } else if (choice == 2) {
            cout << "Student Averages:" << endl;
            for (const Student& student : students) {
                double average = calculateAverage(student.grades);
                cout << student.name << ": " << fixed << setprecision(2) << average << endl;
            }
        } else if (choice == 3) {
            // Sort students based on average grades
            sort(students.begin(), students.end(), [](const Student& a, const Student& b) {
                return calculateAverage(a.grades) > calculateAverage(b.grades);
            });

            cout << "Top Performers:" << endl;
            for (const Student& student : students) {
                double average = calculateAverage(student.grades);
                if (average > 0) { // Only display students with non-zero averages
                    cout << student.name << ": " << fixed << setprecision(2) << average << endl;
                }
            }
        } else if (choice == 4) {
            break; // Quit the program
        } else {
            cout << "Invalid choice. Please try again." << endl;
        }
    }

    return 0;
