Error Questions
Runtime Errors
- Occur during the execution of a program, often due to invalid user input or unexpected conditions
- Examples:
- Division by zero
- Out-of-range values
- Null pointer exceptions
- Can be difficult to detect and debug, as they may not be caught by the compiler
- Often require additional error handling code to prevent program crashes
Syntax Errors
- Occur when the code violates the programming language's syntax rules
- Examples:
- Missing or mismatched brackets
- Incorrect use of keywords
- Unclosed strings
- Typically caught by the compiler during the compilation phase
- Can be easily fixed by correcting the syntax mistakes
Logical Errors
- Occur when the code is syntactically correct but produces incorrect results
- Examples:
- Incorrect algorithm implementation
- Incorrect variable initialization
- Off-by-one errors
- Can be difficult to detect, as they may not produce obvious errors
- Often require thorough testing and debugging to identify and fix
Semantic Errors
- Occur when the code is syntactically correct but does not meet the intended purpose or requirements
- Examples:
- Incorrect function implementation
- Misunderstanding of the problem domain
- Incorrect data representation
- Can be difficult to detect, as they may not produce obvious errors
- Often require a deep understanding of the problem domain and the code's intended purpose
Exception Handling
- A mechanism to handle runtime errors in a program
- Allows the program to recover from unexpected errors and continue executing
- Examples:
- Try-catch blocks
- Error codes
- Exception classes
- Important for writing robust and reliable code that can handle unexpected situations
- Should be used judiciously to avoid masking errors and to provide informative error messages
Error Types
- Runtime errors occur during program execution, often due to invalid user input or unexpected conditions, and can be difficult to detect and debug.
- Examples of runtime errors include:
- Division by zero
- Out-of-range values
- Null pointer exceptions
- Runtime errors require additional error handling code to prevent program crashes.
Syntax Errors
- Syntax errors occur when the code violates the programming language's syntax rules.
- Examples of syntax errors include:
- Missing or mismatched brackets
- Incorrect use of keywords
- Unclosed strings
- Syntax errors are typically caught by the compiler during the compilation phase and can be easily fixed by correcting the syntax mistakes.
Logical Errors
- Logical errors occur when the code is syntactically correct but produces incorrect results.
- Examples of logical errors include:
- Incorrect algorithm implementation
- Incorrect variable initialization
- Off-by-one errors
- Logical errors can be difficult to detect and often require thorough testing and debugging to identify and fix.
Semantic Errors
- Semantic errors occur when the code is syntactically correct but does not meet the intended purpose or requirements.
- Examples of semantic errors include:
- Incorrect function implementation
- Misunderstanding of the problem domain
- Incorrect data representation
- Semantic errors can be difficult to detect and often require a deep understanding of the problem domain and the code's intended purpose.
Error Handling
- Exception handling is a mechanism to handle runtime errors in a program.
- It allows the program to recover from unexpected errors and continue executing.
- Examples of exception handling include:
- Try-catch blocks
- Error codes
- Exception classes
- Exception handling is important for writing robust and reliable code that can handle unexpected situations.
