Memvisualizer: C, One Step at a Time
An interactive C debugger that visualizes variables, pointers, arrays, recursion, threads, mutexes, and simulated memory as code runs.
Field notes
The simulator exposes memory after each highlighted operation, letting users inspect object values, addresses, byte layouts, and pointer destinations rather than relying only on final program output. Its thread model is deliberately bounded: scheduling is interleaved rather than delegated to operating-system threads, with reproducible seeds and manual next-thread controls. The page also documents notable exclusions, including atomics, condition variables, detached threads, and pthread_exit, making the teaching model’s boundaries unusually explicit.
