                                   to learn about:

                                            C++ Character Set                 More Solved Programs





                 Before creating programs in C++, let us first learn about its fundamental concepts. This chapter
                 introduces you to the basic concepts of C++ such as character set and tokens used in C++
                 programming.

                     C++ CHARACTER SET

                 A character set refers to the letters, digits or special symbols that can be used to write programs
                 in C++ language. These are:

                              Characters                                        Uses

                     Letters                        A–Z or a–z
                     Digits                         0–9

                     Special symbols                ~ ‘ ‘ ! @ # $ % ^ & ( ) * - _ + = : \ ] { } ; “ < > , ? | `
                 Tokens of C++


                 Tokens are the smallest individual units of a C++ program. These are divided into the following
                 categories:
                      Keywords                                 Data Types                       Variables

                      Constants                                Delimiters                       Operators
                 Let us learn about these in detail.
                 Keywords


                 Keywords are the reserved words which cannot be used as variable names as they carry a special
                 meaning for the compiler. In C++, keywords are case sensitive.
