C++ — High-Performance Systems Programming Language

Build fast, reliable, and efficient software with uncompromising performance, low-level control, and modern abstractions.

Why C++

Unmatched Performance

Zero-cost abstractions and direct hardware access deliver performance that rivals assembly language.

Low-Level Control

Fine-grained memory management and system-level programming for complete control over your applications.

Modern Abstractions

C++20 and C++23 bring concepts, ranges, coroutines, and modules for expressive, type-safe code.

Vast Ecosystem

Decades of libraries, frameworks, and tools spanning every domain from games to finance.

Backward Compatibility

Leverage existing codebases with seamless interoperability across C++ standards.

Industry Standard

Trusted by major tech companies for critical infrastructure, operating systems, and real-time systems.

Modern C++ Features

Concepts

Define template requirements with clear, compile-time constraints that improve error messages and code clarity.

Ranges

Composable algorithms and lazy evaluation for elegant, efficient data processing pipelines.

Coroutines

Write asynchronous code that reads like synchronous code with first-class coroutine support.

Modules

Faster compilation and better encapsulation with the modern alternative to header files.

Memory Safety

Smart pointers, RAII, and modern best practices minimize memory leaks and undefined behavior.

#include <iostream>
#include <ranges>
#include <vector>

// Modern C++20 with concepts
template<typename T>
concept Numeric = std::integral<T> || 
                  std::floating_point<T>;

template<Numeric T>
T square(T value) {
    return value * value;
}

int main() {
    std::vector numbers{1, 2, 3, 4, 5};
    
    // Ranges and views
    auto squared = numbers 
        | std::views::transform(square<int>)
        | std::views::filter([](int n) { 
            return n > 5; 
          });
    
    for (int n : squared) {
        std::cout << n << " ";
    }
    // Output: 9 16 25
    
    return 0;
}

Getting Started

Install a Compiler

Choose from industry-leading compilers with excellent C++20/23 support:

  • GCC — GNU Compiler Collection with comprehensive standards support
  • Clang — Modern compiler with excellent diagnostics and tooling
  • MSVC — Microsoft Visual C++ for Windows development

Hello World

#include <iostream>
#include <string_view>

int main() {
    constexpr std::string_view message = 
        "Hello, Modern C++!";
    
    std::cout << message << std::endl;
    
    return 0;
}

Compile with:

g++ -std=c++20 hello.cpp -o hello
