for the above reasons, the number of characters successfully written to buffer is returned (excluding the end of '% ') if there is enough memory space. Therefore, if the return value equals size or greater than size, the character that is output to buffer is truncated, and a negative number is returned if an error is encountered during the output.[CPP]View Plaincopy

In actual programming, sometimes the function does not know how many parameters need to be passed before it can be determined during program execution. To a certain extent, it also hurts programmers. In fact, in C/C ++, a macro va_arg () that can be used to pass the variable length parameter list has been defined ().
First, let's look at an example, and then analyze the content and details related to the va

Each iteration: update each iteration; indicates that the vuser uses a new value for each iteration of the script.
The value of each occurrence is updated each time. This indicates that the vuser uses the new value when each parameter appears.
Once is updated only once. This means that the vuser only updates the parameter value once during the running of the solution.

Currently, many commonly used UML tools do not support objective-C, which is inconvenient to draw UML. You must manually convert the objective-C syntax parameter list to the UML or C ++ syntax. It is laborious and error-prone.So I want to write a tool that automatically converts the parameter list
1. A simple implementation of a mutable parameter listWhen a method is called, the number of arguments or the type of the method is unknown, which is called a mutable argument list. In previous Java code, you could use an object array to implement such a function. Because all classes are directly or indirectly inherited from the object class. Varargs.java

When a named parameter is defined without passing in a parameter to a function, arguments returns undefined as a named

When you want to pass the argument is already a list, the function calls to accept separate parameters, this time can consider the parameter list split:

too many parameters. But this problem is easy to solve, simply add the test. Second, a function cannot handle more than 5 values. To solve this problem, you only have to add some similar code to the already bloated code. There is also a more serious problem: the correspondence between the real parameter and the formal parameter is not necessarily accurate.STDARG macromutable
