These errors can occur due to various reasons, such as coding mistakes, incorrect logic, or unexpected user inputs. Software errors can affect the performance and functionality of applications, leading to crashes or incorrect outputs. Identifying and fixing software errors is a crucial part of the software development process. Developers use various techniques, such as debugging and testing, to locate and resolve these issues. Proper error management helps ensure that software applications, like web browsers or mobile apps, run smoothly and provide a good user experience.
