Welcome to C++ Project 9 - Student Grade System

This project will guide you through creating a student grade system in C++ where you can store student names and their grades, then retrieve the average grade and the highest grade in the class.

Hardware Setup

Ensure you have the following hardware components:

A computer with internet access.
A keyboard and mouse for typing and navigation.

Software Requirements

Here are the software tools you'll need for this project:

Visual Studio Code or CLion - These are popular Integrated Development Environments (IDEs) for C++ development.
GCC or Visual Studio - Required to compile and run C++ programs.

Knowledge Prerequisites

To successfully complete this project, you should be familiar with the following concepts:

Basic understanding of C++ syntax.
Understanding of arrays or vectors and basic input and output operations in C++.

Project Steps:

Done

Download and install Visual Studio Code or CLion.
Ensure you have a C++ compiler installed. For example, you can install GCC or use the built-in compiler in Visual Studio.

Done

Open your chosen IDE (Visual Studio Code or CLion).
Create a new file named student_grade_system.cpp.

Done

Open the student_grade_system.cpp file in your IDE.

Type the following code:


#include <iostream>
#include <vector>
#include <string>

using namespace std;

class Student {
public:
    string name;
    float grade;

    Student(string n, float g) {
        name = n;
        grade = g;
    }
};

void displayGrades(const vector<Student> &students) {
    for (const auto &student : students) {
        cout << student.name << ": " << student.grade << endl;
    }
}

float calculateAverage(const vector<Student> &students) {
    float sum = 0;
    for (const auto &student : students) {
        sum += student.grade;
    }
    return sum / students.size();
}

Student findTopStudent(const vector<Student> &students) {
    Student topStudent = students[0];
    for (const auto &student : students) {
        if (student.grade > topStudent.grade) {
            topStudent = student;
        }
    }
    return topStudent;
}

int main() {
    vector<Student> students;
    string name;
    float grade;
    char choice;

    do {
        cout << "Enter student name: ";
        cin >> name;
        cout << "Enter student grade: ";
        cin >> grade;
        students.emplace_back(name, grade);

        cout << "Do you want to add another student? (y/n): ";
        cin >> choice;
    } while (choice == 'y' || choice == 'Y');

    cout << "\nStudent Grades:\n";
    displayGrades(students);

    float average = calculateAverage(students);
    cout << "\nAverage Grade: " << average << endl;

    Student topStudent = findTopStudent(students);
    cout << "Top Student: " << topStudent.name << " with grade " << topStudent.grade << endl;

    return 0;
}

Save the file.

Done

Open the terminal in your IDE and navigate to the directory containing student_grade_system.cpp.
Type the following command to compile your application:
```
g++ student_grade_system.cpp -o student_grade_system
```
Type the following command to run your application:
```
./student_grade_system
```
Enter student names and grades, and see the average grade and top student.
