r/AskComputerScience on Reddit: Difference between runtime error and syntax error
October 17, 2020 -
I’ve been having a mid life crisis trying to figure out the difference even though I do get the gist of it but when it’s applied to examples I can’t seem to look at code and be like “oh yeah, runtime error” or “oop syntax error!” and I would just like to know how other people think about it to try to help my understanding more. Also is compile error the same thing as syntax error?

Syntax error = check your code mate because for a reason it's not even compiling (missing semi colon, wrong variable name, missing a bracket) Runtime error = you code did compile and it's actually running but surprise surprise, something broke and you need to fix that (logic errors, like trying to use a variable which value is null)

Syntax errors are a subset of compiler errors. A compiler error is anything that prevents code correctly being converted into an executable (or library). Runtime errors are any errors encountered when using that executable or library. Syntax is a linguistics term, because we use languages to communicate with compilers. So syntax errors are any language we use that the compiler doesn't understand. These can't ever be runtime since the compiler can't build the executable. Note that there are other reasons the compiler fails, like if a needed library is missing. Runtime errors are logic errors, not linguistics. The compiler understood you, but what you said has some inconsistency. Like you want to dereference an uninitialized pointer. Or you want to use more memory that the system allows. This can get a bit blurry because we design languages to prevent logic errors. Can't deference an uninitialized pointer if the language we use assumes all pointers are initialized. So whether an error is syntactic or runtime is specific to the language and tools being used.

Typescript: Runtime vs Compile time errors — What’s the difference? | by Terence Jefferies | Medium
March 25, 2024 - This is an important distinction to make when working with Typescript. The code that is executed by the end-user is stripped of everything Typescript-specific. As a result, you cannot rely on types to make runtime decisions.

Error Types in Python
Many times though, a program results in an error after it is run even if it doesn't have any syntax error. Such an error is a runtime error, called an exception. A number of built-in exceptions are defined in the Python library.

Exception errors are usually Runtime errors where the error is only detected as the program is running and an unexpected value is met, for example the user typing a string when the program expects an integer.

Each type of error—syntax, runtime, and logic—shows itself in a different way. Also, some strategies may be more useful for certain types of errors compared to others. In order to understand programming errors, we should understand that code gets executed in two stages.

r/csharp on Reddit: Compile Time vs. Runtime Examples Cheat Sheet?
September 20, 2024 -
I know the difference between compile time and runtime errors, but does anyone have a cheat sheet, flashcards, free training resources, etc. specifically focused on being able to identify whether specific code will cause a compile time or runtime error? This was part of several questions on a test that I took previously and will need to retake and would love some good resources to memorize this or learn easy rules of thumb that will help identify which error would come up. This is a written test with no other resources available, so I cannot just test the code to see if it compiles. I'm pretty new to all of this, so please excuse me if I worded anything incorrectly. Thank you!

This is one of those things where I think you need to learn the concept instead of trying to memorize it, mainly because there are far too many variations to memorize. Compile time errors are things that are illegal in the language, causing the compiler to not understand what instruction to write. For example, referencing a symbol that doesn't exist. Syntax errors that the compiler can't understand. They result in the application never being built into a runnable product. For these, you will really need to study the language syntax to identify them. Runtime errors are any errors that are produced when the compiled application is running. So, basically, if they are an error, but not a compile time error, then they are a runtime error. There's kind of a middle ground too that I wouldn't expect them to be quizzing you on since it's typically compiler or even IDE specific, but that is stuff like static analysis tools that can be plugged into the compilation step and produce a compile time like error that prevents the application from building. Typically these look for code smells or other developer pitfalls, or enforce organization/team rulesets. I think it would be a bit unfair for them to quiz you on this type of stuff though.

What is the difference between a syntax error and a runtime error? | TutorChase
A syntax error is a mistake in the code's structure, while a runtime error occurs during the program's execution. A syntax error, as the name suggests, is related to the syntax or structure of the programming language.

October 11, 2017 - A runtime error is an application error that occurs during program execution. Runtime errors are usually a category of exception that encompasses a variety of more specific error types such as logic errors, IO errors, encoding errors, undefined object errors, division by zero errors, and many more.

A run time error will only occur when the code is actually running. These are the most difficult - and lead to program crashes and bugs in your code which can be hard to track down.
An example might be trying to convert a string: "hello" into an integer:
string helloWorld = "hello";
int willThrowRuntimeError = Convert.ToInt32(helloWorld);
The compiler may not see this as a problem but when run an error will be thrown.
Compiler errors are due to inaccuracies in code, where the compiler throws an error to alert you to something which will not compile, and therefore cannot be run.
An example of a compiler error would be:
int = "this is not an int";

A runtime error happens during the running of the program. A compiler error happens when you try to compile the code.
If you are unable to compile your code, that is a compiler error.
If you compile and run your code, but then it fails during execution, that is runtime.
