Bugs

A bug is an unintended defect in a software program that leads to incorrect or undesired outcomes. Bugs can result from coding errors, design flaws, or unintended interactions between software components. They often manifest as crashes, freezes, incorrect outputs, or malfunctions in functionality.
Bugs are categorized by severity, ranging from minor inconveniences to critical failures that halt operations. Common types include syntax errors, logic errors, and runtime errors. Debugging—the process of identifying and resolving bugs—is a crucial step in software development. Tools like debuggers, code analyzers, and testing frameworks are commonly used.
