C + + input/output is provided by the standard library, which supports reading and writing of files, control Windows, and string objects.8.1 Object-oriented librariesThe IO type is defined in three separate header files, iostream defines the type of

There are several basic input functions in the C language:Get character Seriesint fgetc (FILE *stream);int getc (FILE *stream);int GetChar (void);Get Row SeriesChar *fgets (char * restrict S, int n, FILE * restrict stream);Char *gets (char *s);//may

One, C + + compilation modeTypically, in a C + + program, only two types of files ——. cpp files and. h files are included. Where. cpp files are referred to as C + + source files, and the. h file is called the C + + header file, and the source code

A preprocessing directive is the ability to conditionally skip code Snippets (sections) in the source file, report errors (error messages and line numbers), and warning conditions when the compiler compiles code, as well as describe the different

Assertions are something that has been done very early, and can only be used with the introduction of the Cassert header file. Often assert is used to check for behavior that is not possible, to ensure that the developer at the beginning of the

C++11 improved the compiler's parsing rules, as much as possible to resolve multiple right angle brackets (>) to the template parameter terminator, easy to write template-related code.1. Right angle brackets for the templateIn the previous C + +

A static constructor is a new feature of C #, which seems to be seldom used. But we need to use it when we want to initialize some static variables. This constructor belongs to the class, not to the instance where it belongs, meaning that the
