Features

• Add, update, delete students
• Display all students
• Search by ID or name
• Statistics (total, average, min, max grades)
• Sort by ID, name, or average
• Save/load students to/from CSV file

---

Requirements

• C++17 compiler (g++, clang++, MSVC)
• CMake (optional, recommended for large projects)
• Ninja or MinGW Makefiles (optional, for building with CMake)

---

Quickstart

Using CMake (Recommended)

Cross-platform solution for Windows and Linux.

1. Create a build directory:

cmake -S . -B build -G "MinGW Makefiles"

On Linux, you can use -G "Unix Makefiles" or -G "Ninja" if installed.

2. Build the project:

cmake --build build

3. Run the executable:

• Windows:

build\main.exe

• Linux:

./build/main

---

Using g++ directly (Simple)

For small projects or if you don’t want to use CMake:

g++ main.cpp FileManager.cpp InputUtils.cpp StudentRepository.cpp -std=c++17 -Wall -Wextra -O2 -o main

Run:

• Windows:

main.exe

• Linux:

./main

Notes

• Make sure students.csv exists or will be created in the same folder as the executable.
• On Windows, it is recommended to use MSYS2 or MinGW for building with CMake.
• On Linux, make sure you have g++ and make installed.
