Application of Variable Parameter Macros in

Since vs2005, VS has finally supported the variable parameter macro function of c99. It was only today that it was too surprising that Microsoft was always behind GCC.

# Define myprintf (FM,...) printf (FM # "/N" ,__ va_args __)

Call: myprintf ("ABC"); after the macro is expanded, it is printf ("ABC/N"); that is, the function of automatic carriage return after the string. The above is just a simple application, and the biggest benefit will be in XML parsing. I will not discuss it in detail here.
