In C language programming, we inevitably need to access variable parameter functions. For C languages that do not support function polymorphism, using variable parameters and macro-defined functions is a good way to implement function polymorphism.
C # its built-in X-in conversion function is as follows:
// Convert decimal to binaryConsole. WriteLine (Convert. ToString (69, 2 ));// Convert decimal to octalConsole. WriteLine (Convert. ToString (69, 8 ));// Convert decimal to hexadecimalConsole.
Java log Combat and analysis
Log is one of the basic skills that programmers must master, and if you write software without a log, you can say you are not a real programmer.
Why do I have to keep a diary?
