How to Fix Syntax Error

How to Fix Syntax Error thumbnail
Tokens in a programming language are typically symbols, commas, numbers and operators.

In the field of computer science, a syntax error occurs when there is an error within the syntax of a string of characters or tokens that violates the rules in a programming language. Syntax is a set of rules that define the strings of characters that are considered to be correctly structured in a particular language. A program will not compile--translate a program into machine language--until all syntax errors are corrected. While syntax errors can be easily located in simple programs, complex programs are made up of hundreds or thousands of lines of code. Today, software development kits, or SDKs, offer debugger programs that help locate the syntax error.

Instructions

    • 1

      Open your code and compile the program. The compiler will stop running and highlight the sections of the code containing syntax errors.

    • 2

      Locate the debugger tool in the programming language. You can find the debugger tool usually on the toolbar often under the "Tool" tab as "Debug" or "Debug and Compile."

    • 3

      Read the code carefully and correct the necessary errors. Correcting a syntax error will differ depending on the type of error that has occurred. Most common syntax errors are corrected by replacing an incorrect "character" or "formula" with one that conforms to the syntax rules of the programming language.

    • 4

      Check the code to see if you've misplaced or missed any parentheses or brackets within the program or tokens. Tokens are characters, categorized in a programming language as symbols--commas, numbers and operators.

    • 5

      Save any changes and run the compiler.

Tips & Warnings

  • Debug and compile your program often to reduce the amount of time you spend trying to find syntax errors.

  • Save your work often, especially after every successful test run.
