About the C Playground
Code Visualizer’s C playground lets you write, compile, and execute C code directly in your browser. Watch as pointers resolve to stack and heap memory addresses, variables update across execution frames, and malloc and free allocations are visually mapped in real-time.
Master foundational concepts like pointer arithmetic, pass-by-reference, array indexing, structs, dynamic memory management, and stack vs heap allocation. Set breakpoints, inspect raw memory addresses, and eliminate segmentation faults and memory leaks visually. An essential tool for CS students, systems programmers, and embedded software learners.
