ZenCompiler delivers an ultra-fast modern C++ online compiler powered by GCC 9.2. Write, compile, and execute C++ programs with Standard Template Library (STL) containers (std::vector, std::map, std::unordered_set, std::priority_queue), 2D vectors, nested map of maps, smart pointers (std::unique_ptr, std::shared_ptr), pointer of pointer structures, operator overloading, lambda expressions, and RAII resource management in an interactive cloud IDE.
Built for high execution velocity, seamless STDIN interactivity, and zero configuration.
Comprehensive C++ Standard Template Library (STL) support with vectors, queues, deques, sets, and priority_queue
Modern C++17/C++20 language features including auto deduction, structured bindings, operator overloading, and lambdas
Support for 2D vectors (vector<vector<int>>) and nested associative containers (map<string, map<string, int>>)
Step-by-step memory visualizer for tracking pointer references, object lifecycles, and stack frames
Interactive STDIN terminal for fast competitive programming inputs (std::cin, std::getline)
Compiled with g++ -O2 -std=c++17 -Wall inside secure Linux container workers with direct standard library linkage and instantaneous compilation feedback.
Competitive programming (LeetCode, Codeforces, HackerRank), algorithm design (BFS/DFS, Dijkstra with priority_queue), data structures coursework (trees, graphs, heaps), and high-performance software modeling.
Everything you need to know about compiling and executing C++ on ZenCompiler.
