Syntax Errors {#syntax-errors}
Syntax errors occur when the code violates the rules of a programming language. These errors are often detected during the compilation phase and can prevent the software from running altogether. Common syntax errors include missing semicolons, unmatched parentheses, or incorrect variable declarations.
Logic Errors {#logic-errors}
Logic errors, also known as semantic errors, occur when the code does not produce the desired output due to flawed logic or incorrect algorithmic implementation. These bugs can be particularly tricky to identify as the code may run without any syntax errors, but the results are not as expected. Logic errors can lead to software crashes, incorrect calculations, or unexpected behavior.
Runtime Errors {#runtime-errors}
Runtime errors, also referred to as exceptions or runtime exceptions, occur during the execution of a program. These bugs often result from invalid input, memory issues, or unexpected system conditions. When a runtime error occurs, the program may terminate abruptly or display error messages to the user. Common runtime errors include division by zero, null pointer references, and out-of-bounds array accesses.
Interface Errors {#interface-errors}
Interface errors occur when there are discrepancies or malfunctions in the communication between different software components or modules. These bugs can lead to issues with data exchange, synchronization problems, or incorrect behavior when interacting with external systems or APIs.
