cee.studio

cee.studio is a browser-based online IDE for C language development featuring a debugger that lets you visualize code execution. The recorded execution can be rewound to any statements and replayed. It provides a visual effect of C code statement by statement. In each points-to graph, node represents memory space, directed edge represents points-to relation. Both node and edge are clickable. Clicking a node will highlight the statement that allocates a memory space. Clicking an edge will highlight the assignment statement that creates a points-to relation. The following GIF shows a recorded execution of creating a single linked list. It can give programmers/students a complete view of how memory spaces are used and connected.
