Token

• Token:-

               In C-language, a source program consists of keywords, variables (or identifiers), constants, operators, punctuators etc. These elements of a program known as tokens.

• For Example:-

                    main()
                    {
                          float temp, xy4;
                          xy4 = 10;
                          temp = xy4 + 10 * 2;
                    }


                 In the above program;

1. ''main'' is a special identifier and temp, xy4 are variables.
2. ''float'' is a keyword.
3. The punctuators are; { , " , '' , ( , ) , ; , white spaces etc.
4. The operators are : , = , *  , + , etc.
