IGCSE Algorithms And Pseudocode Foundations For G8 Practice Exam

Debugging is the process of finding and fixing errors in code. It involves identifying where a problem occurs, understanding why it happens, and making changes so the program runs correctly. When you debug, you might run the program with test inputs, add print statements or use a debugger to pause and inspect variables, and step through the code to observe how data flows and where it deviates from the intended behavior. This is about repairing the program so it works as intended. Dry-run is a technique for tracing what would happen step by step without actually executing the program, useful for spotting logic mistakes but not the act of altering code to fix them. Overflow refers to a specific kind of error where a value exceeds what a data type can hold, which is a bug type rather than a process. A binary shift is a low-level operation that moves bits left or right, not a method for correcting mistakes in code.
