Preparing for debugging (defensive code)
In the programming world, a bug refers to defects or problems that prevent code or programs from running normally or as expected. Debugging is the process of finding and resolving those defects. Debugging methods include interactive debugging, unit testing, integration testing, and other types of monitoring and profiling practices.
Defensive programming is a form of debugging approach that ensures the continuing function of a piece of a program under unforeseen circumstances. Defensive programming is particularly useful when we require our programs to have high reliability. In general, we practice defensive programming to improve the quality of software and source code, and to write code that is both readable and understandable.
We can use exceptions to handle unexpected inputs or user actions that can potentially reduce the risk of crashing our programs and make our software behave predictably.
