Tracing Code Manually

Code tracing means executing code in your head (or on paper) exactly as a computer would, step by step. This skill is essential for debugging and understanding how code works. The Variable Table Method Create a table tracking the value of each variable after every line executes. Let's trace this code: Tracing Loops Loops require tracking values across multiple iterations. Trace this code that calculates the sum of digits: Manual tracing builds the mental model you need to debug. When code does not produce the expected output, tracing through it step by step reveals exactly where your assumption diverges from what the computer actually does. The variable table method is also invaluable for understanding unfamiliar code. Tracing someone else's loop line by line is often faster than reading t
