Syntaksivirhe

Syntaksivirhe is a Finnish term that translates to "syntax error" in English. It refers to an error in the structure or grammar of a statement in a programming language or a formal language. When a computer program attempts to interpret or execute code containing a syntax error, it will typically fail to compile or run. The program's parser, which checks the code against the language's rules, cannot understand the incorrect structure and reports the error.

Syntax errors are among the most common types of errors encountered by programmers. They can arise from a variety of mistakes, such as misspellings of keywords, incorrect placement of punctuation like semicolons or parentheses, missing or extra characters, or failing to follow the specific rules for constructing commands or statements in a given language. For example, in many programming languages, a statement must end with a semicolon. Forgetting this semicolon would result in a syntax error. Similarly, using an opening parenthesis without a corresponding closing parenthesis would also be a syntax error.

Detecting and correcting syntax errors is a crucial part of the software development process. Programming environments, such as Integrated Development Environments (IDEs), often provide tools to highlight syntax errors as they are typed, helping developers identify and fix them quickly. These errors must be resolved before the program can be successfully translated into machine code or interpreted for execution. Unlike semantic errors, which relate to the meaning of the code, syntax errors are purely about the form and structure of the code.
