Example 1.1, the first C + + program in this tutorial, outputs a single line of characters: "This is a C + + programs." The procedure is as follows: #include //Include header file iostream Using namespace STD; //Using the namespace

This section is mainly about why Const,inline is better than # define, summed up as follows:1 If you use # define, the compiler just foolishly replaces the contents of the define with the defined variables, takingAspect_ratio, when compiling the
