c Basic Syntax

	The basic structure of C programming is easy and it will be help full to understand other building blocks of the C programming language. C Programming Tokens: A token in c programming is either a keyword, an identifier, a constant, a string literal, or a symbol. For example, the following statements of a c program consist  five tokens: printf("Hey, World! \n"); The five tokens are: 1.printf 2.( 3."Hey, World! \n" 4.) 5.; Semicolons(;) The semicolon is a statement terminator in a c program. Each statement in c must be ended with a semicolon. For example,the two different statements: 1.printf("Hey, World! \n"); 2.return 0; each statement is ended with a semicolon. Comments: Comments helps to easily understand your C program and they are not compile by the compiler. They start with /* and terminates with the characters */ as shown below: /* c program for print hello */ You cannot have comments within comments. Identifiers: A identifier is a name used to identify a variable, function, or any other user-defined item. An identifier would be start with a letter A to Z or a to z or an underscore _ followed by zero or more letters, underscores, and digits (0 to 9). the followimg symbols cannot be used within identifiers .@, $, and % . Here are some examples of acceptable identifiers: mohd       zara    abc   move_name  a_123 myname50   _temp   j     a23b9      retVal Keywords: The following list shows the reserved words in C. These reserved words may not be used as constant or variable or any other identifier names. auto       else        long       switch break    enum    register                typedef case       extern  return   union char       float       short     unsigned const     for          signed   void continue              goto       sizeof    volatile default if             static     while do           int           struct    _Packed double
