Variable parameters.1: Must have an advance parameter, (ie: ...) You must have a parameter before you can calculate the address of the first unknown parameter that follows. Once you know the address of the first unknown parameter, you can format the

Before C++11, there were two typical problems that were constrained by the bad template functionality that caused the code to repeat itself, which is the function object and tuple. For function objects, a return type parameter and n parameter type

Variable Length Parameter (*, **), Variable Parameter Variable Length Parameter Python also supports variable-length parameter lists. Variable Length parameters can be tuples or dictionaries.1. tuples When a parameter starts with *, the variable

This article is intended for beginners in PHP learning, so let's take a concrete example to explain it. First, we need to write a PHP function to calculate the two number of the and can be written as follows: /** * Calculates the sum of two numbers

__VA_ARGS__ is a variable-parameter macro that few people know about this macro, which is the new C99 specification, and currently appears to be supported only by GCC (VC6.0 compiler does not support it).The implementation idea is that the last

Repeating Parameters Scala allows you to specify that the last parameter can be repeated (variable-length arguments) when defining a function, allowing the function caller to invoke the function using a variable-length argument list, using "*" in

have been written around printf to print debugging information, do not need to be a comment out. After the Internet query found there are many ways to debug printing, parameters variable and convenient one-time switch. #define DEBUG (FMT,...) printf

Va_list Arg; Declares a variable arg of type va_list, which is used to access the indeterminate part of the parameter list;Va_start (Arg,val); The first parameter is the variable name of Va_list, and the second parameter is the previous parameter of

Today, we can see in csdn that this example is used to assign values to an array and va_list is used. I have never been very concerned about the use and details of this variable parameter function. In the past, I used int argc and char * argv [] to

Using the macros va_arg, va_end, and va_start, You can input variable parameters in the function. Such as printf and sprintf. When I wrote a variable parameter list myself today, I found several notes.   The excerpt is as follows: Here:

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

Preface: When writing a program, we always add some printf and other statements to output debugging information, however, the most inconvenient part of the printf statement is that when we need to release a program, we need to delete these
