Definition: Prologuing is a technique used in computer programming to simulate code execution and debugging. In other words, it's an approach that allows one to inspect the behavior of a program at runtime without having to write actual code or run it on a machine. In simple terms, prologuing involves using a debugger or an interpreter to step through the flowchart of your program's state. This allows you to see what variables are holding values and how they are being modified. It can be used for debugging
