What is a syntax error?

[Chrisch]

I am using c, visual basic in my program. I have noticed that many time i get syntax error? Does any one know what is a syntax error? Is this error belongs to any declaration of variable or syntax which use to define the variable. Any help will be extremely appreciated.

Syntax is the order in which words and phrases are put together, such as a URL (web address) which consists of several phrases that are strung together to define a location or service on the Internet. A SyntaxError is thrown when the JavaScript engine encounters tokens or token order that does not conform to the syntax of the language when parsing code.

If a syntax error is encountered during compilation it must be corrected if the source code is to be successfully compiled. For compiled languages syntax errors occur strictly at compile-time. A program will not compile until all syntax errors are corrected. An attribute that often separates commercial quality compilers from academic projects is the extent to which an attempt is made to automatically correct the error and continue processing the source code.

Every language has got set of rules. If you make a mistake while using the language, then it is called syntax error. I c++ every statement ends with a semicolon, printf and scanf arguments should be placed in ( ).
