Introduction:Before the possibilities of the newC + + language standard,c++11, the use ofTemplatesWas quite limited if it came to implementing for instancefunction Objects (functors)&Tuple Facilities. Implementing these sort of things using earlier
1, Introduction variadic functionA variable parameter function is a function that can change the number of parameters. e.g. printf ();int printf (const char *format, ...);printf ("%d%s\n", i,s);C language can support variadic functions, one of the
3.6 Variadic MacrosA macro can is declared to accept a variable number of arguments much as a function can. The syntax for defining the macro was similar to that of a function. Here are an example: #define EPRINTF (...) fprintf (stderr,
Differences in the compiler's implementation of the function pack extension for C + + 11 parameter templates (Variadic template)The topic is quite round the mouth. C + + 11 is not too much of a good thing, but the Variadic template is certainly one
Variadic Macros is function-like macros that contain a variable number of arguments.RemarksTo use Variadic macros, the ellipsis is specified as the final formal argument in a macro definition, and the Replacem ENT identifier __va_args__ May is used
