Code errors, often referred to as "bugs," occur when a computer program does not function as intended. These errors can arise from various issues, such as syntax mistakes, logical flaws, or incorrect data types. Debugging is the process of identifying and fixing these errors to ensure the program runs smoothly. There are different types of code errors, including syntax errors, which happen when the code does not follow the correct format, and runtime errors, which occur during program execution. Understanding these errors is crucial for developers to create efficient and reliable software applications.
