In programming, errors that occur within a sequence of characters can broadly be categorized into several types:
1. **Syntax Error**: This is one of the most common types of errors and occurs when the code does not conform to the rules of the programming language. For example, missing semicolons, mismatched parentheses, or incorrect indentation can all lead to syntax errors.
2. **Semantic Error**: These occur when the syntax is correct, but the code doesn't do what the programmer intended. For example, using an operator incorrectly (e.g., using addition instead of multiplication) can lead to a semantic error.
3. **Runtime Error**: This type of error happens while the program is running, often due to invalid operations. Examples include dividing by zero or trying to access an out-of-bounds index in an array.
4. **Logical Error**: This occurs when the program runs without crashing, but produces incorrect results. Logical errors can be hard to detect because the code is syntactically correct, but the logic implemented does not align with the intended logic.
5. **Type Error**: This occurs when an operation is performed on an inappropriate data type, such as trying to add a string to an integer.
6. **Compilation Error**: In statically typed languages, this error occurs when the code cannot be compiled due to issues like unresolved references or incorrect type usage.
7. **Indentation Error**: Common in languages like Python, incorrect indentation can lead to errors that affect code execution, as indentation is syntactically significant.
Understanding these categories of errors can help programmers diagnose and fix issues in their code effectively.
