C++ Code Visualizer
Understand C++ memory management at a glance. See pointers resolve, watch stack frames push and pop, trace heap allocations, and visualize RAII and smart pointer lifetimes.
What You Can Visualize
Pointers & References
Watch pointers resolve to memory addresses. See the difference between references and pointers in real-time.
Stack & Heap Memory
Visualize stack frame allocation for local variables and heap allocation for dynamic objects with new/delete.
RAII & Smart Pointers
See how unique_ptr, shared_ptr, and RAII patterns manage resource lifetimes automatically.
Why Use a C++ Visualizer?
C++ gives you direct control over memory — but that power comes with complexity. Dangling pointers, memory leaks, buffer overflows, and undefined behavior are notoriously hard to debug mentally.
Code Visualizer's C++ visualizer makes memory management visual. See exactly where each object lives in memory, when it's allocated, and when it's freed. No more guessing about pointer arithmetic or scope lifetimes.
