Obtain and verify the user name and password from the TXT document.     # Include # include int recog_pwd (char name [20], char PWD [20]); void main () {int isok; char * name = "OSD "; char * Pwd = "123"; if (recog_pwd (name, PWD) = 1)

  In C/C ++, the main () function is used to transmit command line parameters.   To implement the command line parameters, we will define argc and argv in the form of main (INT argc, char * argv []), which can be replaced by your favorite name,

Class { Void SS (){**************}; } Class A has the member function SS (); The following operations can be performed: A *; A * B = NULL; A * c = new (); A-> SS (); B-> SS (); C-> SS (); The access to SS () is successful. The reason is

For the following reasons, you must provide multiple versions for the application: 1: The application has a trial version and a full functional version; 2: Automated operations are required during application testing;  1: Trial Edition For the first

The reason why generic programming (generic programming) was initially proposed is simple and straightforward: the invention of a language mechanism can help implement a general standard container library. The so-called general standard container

C ++ language was originally created as "a better C ", however, this does not mean that the compilation and connection methods used by global variables and functions similar to C in C ++ are the same as those in C. As a language to be compatible
