CodeSamjho is a browser-based code execution visualizer designed to help users understand how programs run step by step. It supports Python, Java, and C++, allowing users to write or paste code and then trace its execution line by line. The tool displays the current state of variables, the call stack, and data structure diagrams, making it easier to follow the logic and flow of a program. It also includes control flow graphs to illustrate the path of execution and an AI debugging assistant to help identify and explain issues in the code. The primary function of CodeSamjho is to provide an interactive learning environment for programming students, educators, and self-learners. Users can input code directly into the browser interface and then step through each line to observe how variables change and how functions are called. The visualizations update in real time, offering a clear view of the program's internal state. This approach is particularly useful for understanding complex concepts such as recursion, pointer manipulation, and data structure operations. Typical use cases include classroom demonstrations, homework assistance, and personal study sessions. For example, a student learning about linked lists in C++ can write the code, step through the insertion or deletion operations, and see the nodes and pointers update visually. An educator might use the tool to explain how a recursive function unwinds by showing the call stack and variable values at each step. The AI debugging assistant can also help users who are stuck by analyzing the code and suggesting corrections or explaining errors. CodeSamjho runs entirely in the browser, requiring no installation or local setup. It is accessible from any device with a modern web browser and an internet connection. The tool processes code on the server side to generate visualizations, but the user interface remains responsive and lightweight. There are no specific hardware requirements beyond a standard computer or tablet. The platform is available at codesamjho.online and is intended for educational purposes, supporting learners at various skill levels.
