Why C++ Is Still on Top, and How a Portfolio Solves Everything
\n\nYou've probably heard: "C++ is hard," "C++ is dying," and other horror stories. The reality, however, is this: C++ still rules in game dev, high-load systems, finance, and embedded development. Neither Unreal Engine, nor Chromium, nor databases like MySQL can do without it.
\n\nBut there's one problem: learning the syntax is only half the battle. An employer wants to see not a diploma, but C++ projects for your portfolio that demonstrate architecture, memory management, and the ability to solve real-world problems. That's why we've gathered 10 ideas — from simple to advanced. Each idea comes with a code example and an explanation of which skill it develops.
\n\nReady to build a portfolio that will give HR goosebumps? Let's go.
\n\n1. Console Text Editor (nano-like)
\nDifficulty: Beginner
\nSkills: File handling, strings, terminal control
A classic that never gets old. You create a simple editor for opening, editing, and saving files. You'll learn to work with fstream, handle key presses, and manage a buffer.
#include <iostream>\n#include <fstream>\n#include <string>\n#include <vector>\n\nclass TextEditor {\nprivate:\n std::vector<std::string> lines;\n std::string filename;\npublic:\n void open(const std::string& file) {\n filename = file;\n std::ifstream in(file);\n std::string line;\n while (std::getline(in, line)) {\n lines.push_back(line);\n }\n }\n void save() {\n std::ofstream out(filename);\n for (const auto& line : lines) {\n out << line << '\\n';\n }\n }\n void run() {\n // Input handling loop goes here\n }\n};\n\n2. Simple HTTP Server (Single-threaded)
\nDifficulty: Intermediate
\nSkills: Sockets, network protocols, request handling
Write a server that accepts HTTP GET requests and serves static files. This is the gold standard for understanding how the internet works. Use sys/socket.h on Linux or winsock2.h on Windows.
#include <iostream>\n#include <cstring>\n#include <sys/socket.h>\n#include <netinet/in.h>\n#include <unistd.h>\n\nint main() {\n int server_fd = socket(AF_INET, SOCK_STREAM, 0);\n sockaddr_in address;\n address.sin_family = AF_INET;\n address.sin_addr.s_addr = INADDR_ANY;\n address.sin_port = htons(8080);\n\n bind(server_fd, (struct sockaddr*)&address, sizeof(address));\n listen(server_fd, 3);\n\n std::cout << "Server started on port 8080\\n";\n // Accept loop and request reading\n return 0;\n}\n\nA project like this in your C++ portfolio immediately shows that you understand the OSI model and can work with low-level network interfaces.
\n\n3. Task Manager (To-Do List) with a Graphical Interface
\nDifficulty: Intermediate
\nSkills: Qt or SFML, MVC pattern, working with databases (SQLite)
Create an application for adding, deleting, and sorting tasks. Use the Qt library — this will give you an understanding of signals and slots, as well as GUI development skills. Add storage in SQLite via sqlite3.h.
#include <QApplication>\n#include <QMainWindow>\n#include <QListWidget>\n#include <QPushButton>\n\nint main(int argc, char *argv[]) {\n QApplication app(argc, argv);\n QMainWindow window;\n window.setWindowTitle("Task Manager");\n \n QListWidget* list = new QListWidget(&window);\n QPushButton* addBtn = new QPushButton("Add Task", &window);\n \n // layout and signal connections\n window.show();\n return app.exec();\n}
