Compiler Checkable Errors

Syntax errors are the only type of errors that a compiler can check. Let's break down what this means.

Syntax Error
- A syntax error occurs when the code violates the rules of the programming language.
- This often happens when a programmer types incorrect syntax, such as missing a semicolon or using the wrong variable type.
- The compiler checks the syntax of the code to ensure that it is valid and can be executed.
- If the code has a syntax error, the compiler will report an error message and the programmer will need to fix the error before the code can be executed.

Logical Error
- A logical error occurs when the code performs an incorrect action.
- For example, the code could be written in a way that produces the wrong output, even though it is syntactically correct.
- The compiler cannot detect logical errors because it does not know what the intended output of the code is supposed to be.

Compiler's Role
- The compiler's role is to translate source code into machine code that can be executed by the computer.
- It does not have the ability to understand the logic behind the code or the desired output.
- Therefore, it can only check for syntax errors and report them to the programmer.
- It is up to the programmer to ensure that the code performs the desired action and produces the correct output.

Conclusion
- In conclusion, a compiler can only check for syntax errors and not for logical errors.
- Programmers must take responsibility for ensuring that their code performs the correct action and produces the desired output.
