How do programming languages handle errors?

Syntax errors are caused by mistakes in the structure or syntax of the code. Common syntax errors include misspelled keywords, missing or misplaced punctuation, incorrect indentation, mismatched brackets or parentheses, and using incorrect operators. To avoid such error, you need to: - Understand the language, familiarize yourself with the syntax rules of the programming language you are using. - Use Code Editors, almost all the IDE integrated with such error detection feature - Maintain consistent indentation, use of brackets/parentheses, and code organization. This makes it easier to spot errors related to code structure. - Pay attention to spelling, casing, variables, and function names. Typos can lead to syntax errors.

Syntax errors are mistakes or omissions in the writing of the code that will prevent the program from working as it should or simply not. The main reason for these errors is non-compliance with the rules, especially of the programming language. To correct these syntax errors, one must first locate the line where the error is located and then modify it considering the standards of the programming language in question. Sometimes an error message helps to locate the error line, but in other conditions it is necessary to search more carefully. Syntax errors can be considered the easiest types of errors to avoid and fix, however they can also be very frustrating.

Generally, this is caught in the IDEs while you are developing itself. When it comes to programming languages like C++ while using Visual Studio the errors are seen while you are typing as Red lines below the code.

In computer programming, a syntax error is when the computer can't understand the instructions you've given it because you didn't use the right words or put them in the right order. So, it's like telling the computer to build a tower, but you didn't follow the building rules exactly, and now the computer doesn't know what to do.

Important types of runtime errors are as under: ZeroDivisionError: It occurs when attempting to divide a number by zero. IndexError: It occurs when trying to access an index that is outside the range of a data structure (e.g., list, tuple). NameError: It occurs when trying to use a variable or function that is not defined. TypeError: It occurs when an operation is performed on an object of an inappropriate type. KeyError: It occurs when trying to access a dictionary key that does not exist. AttributeError: This occurs when trying to access an attribute or method that does not exist for a given object. ImportError: This occurs when there is an issue with importing a module or using a function from a non-existent module.

To help with debugging and keeping an eye on the application's performance, you should also think about tracking exceptions on a regular basis. Make sure exception handling is part of a larger error-handling plan that complies with user expectations and application needs. Also, when dealing with exception handling, it's important to design exception handling strategies that are specific and tailored to the nature of potential errors, avoiding overly broad catch statements that may mask underlying issues. Implement custom exception classes when standard exceptions are insufficient to convey specific details about errors.

In computer games or programs, if something unexpected happens, like trying to do something too hard or not quite right, we have a plan to handle it. We can make sure the program keeps going without crashing. So, exception handling is like having a backup plan or a way to deal with surprises so everything can keep running smoothly.

Having a universal catch looks like a safe strategy but generally, this slows down the performance to a great extent. Because the stack needs to be rebuilt and this will cause performance issues. So the better method is to handle specific exceptions rather than generic exceptions.

Don’t forget to free up the acquired resources if an error occurs (a resource is not always a memory; it can be a file or remote resource ). Use the RAII idiom, try-catch-finally, try-finally block, “using” keyword (c#) to free up the resources.
