C++ powers performance-critical applications from operating systems to game engines, requiring deep knowledge of memory management, templates, and the Standard Template Library. Our C++ code generator uses AI to create modern C++17/20 code with RAII principles, smart pointers, move semantics, and efficient STL usage. Whether you need data structure implementations, algorithm code, class hierarchies, or template metaprogramming, describe your requirements and get production-ready C++ code.
Perfect for game developers building high-performance engines, systems programmers working on low-level code, competitive programmers implementing algorithms, or embedded engineers optimizing for resource constraints. The generated code follows C++ Core Guidelines with proper resource management and zero-cost abstractions.
Generate code using vector, map, set, unordered_map, or deque with proper iterators. Create custom comparators for sorting, implement algorithms with std::find_if, std::transform, std::accumulate, use lambda expressions for predicates, or write range-based for loops. Includes modern C++20 ranges and views for functional-style data processing with lazy evaluation and composition.
Example tasks: "Sort vector of structs by custom field using lambda", "Filter and transform collection with STL algorithms", "Implement binary search on sorted container". The AI generates efficient STL usage with move semantics and perfect forwarding where appropriate.
Create classes with unique_ptr for exclusive ownership, shared_ptr for shared ownership, weak_ptr to break circular references, or implement custom deleters. Generate RAII wrapper classes for resource management, implement the Rule of Five for classes managing resources, use make_unique and make_shared for safe object creation, or build memory pools for performance-critical code.
If porting legacy code, try our C++ to Python converter for prototyping or C++ to C converter for embedded systems.
Generate class hierarchies with virtual functions, implement interfaces with pure virtual methods, create abstract base classes, use multiple inheritance carefully, implement the Strategy or Observer pattern, or build template classes for generic programming. Includes proper constructor/destructor chains, copy/move constructors, and virtual destructors for polymorphic classes.
Create thread-safe code with std::mutex, std::lock_guard, or std::unique_lock. Generate thread pools using std::thread, implement producer-consumer patterns with condition variables, use std::async for asynchronous operations, create atomic operations for lock-free programming, or implement parallel algorithms with std::execution policies. Perfect for multi-core utilization in performance-critical applications.
Generate template functions that work with any type, create template classes for generic data structures, implement variadic templates for arbitrary arguments, use SFINAE for compile-time type selection, or apply template specialization for type-specific optimizations. Create type-safe generic algorithms, container adapters, or policy-based designs that maintain zero-cost abstraction.
Example: "Create template function to find maximum element supporting any comparable type", "Build template stack class with type-safe operations"
Create constrained templates using C++20 concepts, define custom concepts for type requirements, use requires clauses for compile-time validation, implement concept-based function overloading, or write abbreviated function templates. Provides better error messages and clearer intent than SFINAE while enabling more expressive generic programming.
Example: "Create function template requiring Sortable concept", "Define custom concept for Serializable types"
Generate constexpr functions for compile-time computation, create constexpr variables and arrays, implement constexpr if for conditional compilation, use consteval for guaranteed compile-time evaluation, or build compile-time parsers and calculators. Moves computation from runtime to compile time, improving performance and enabling template metaprogramming.
Generate C++ code for game engines, physics simulation, and graphics programming
Create entity-component systems, implement game loop with fixed timestep, build spatial partitioning structures like quadtrees or octrees, generate collision detection code, create animation systems, or implement resource managers. Includes memory-efficient designs for handling thousands of game objects with cache-friendly data layouts and object pooling.
Generate OpenGL rendering code with shaders, create Vulkan initialization and command buffers, implement texture loading, build vertex buffer objects, generate transformation matrices, or create camera systems. Includes proper resource cleanup and modern graphics API best practices for high-performance rendering.
Get efficient, modern C++ code with these best practices
Mention which C++ standard you're targeting: "C++11", "C++14", "C++17", or "C++20". This determines available features like structured bindings, std::optional, ranges, or concepts. Different standards have different performance characteristics and library support.
Good: "Create sorting function"
Better: "Create C++17 sorting function using structured bindings and std::optional"
Ask for smart pointers explicitly: "use unique_ptr for ownership", "shared_ptr for shared resources", "avoid raw pointers". This ensures modern memory management practices and prevents memory leaks. The generator will use make_unique and make_shared for exception safety.
Modern C++ avoids manual new/delete in favor of RAII and smart pointers
Specify if you need cache-friendly code, zero-copy operations, move semantics, or compile-time computation: "optimize for cache locality", "use move semantics", "make it constexpr". The generator will choose appropriate patterns and avoid unnecessary copies or allocations.
C++ excels at zero-cost abstractions and compile-time optimization
Mention needed headers or libraries: "use Boost library", "include STL algorithm header", "use Eigen for linear algebra". This ensures proper includes and uses established libraries when appropriate instead of reinventing functionality.
The generator knows common libraries like Boost, Eigen, and the entire STL
