Variable Arguments in C - Sometimes, you may come across a situation, when you want to have a function that can accept a variable number of arguments (parameters) instead of a predefined number of arguments. The C programming language provides a solution
To call a function with a variable number of arguments, simply specify any number of arguments in the function call. An example is the printf function from the C run-time library. The function call must include one argument for each type name declared in the parameter list or the list of...
You can avoid the crash by putting the loop in a try...catch exception handler or maybe add code to enforce a limit to the number of arguments. But those are only band-aids. In any case, the function (and thus your lovely program) fails -- the "average" that you display won't be...

Using a function that accepts a variable number of arguments can be very useful: this provides a lot of flexibility and reduces the clutter in the function signature. Besides, it does not make any assumptions about the number of needed arguments, which can be appropriate in multiple scenari...
C supports functions that take a variable number of arguments.The va_* family of macros, defined in the standard header file , providea portable way for a function to examine its arguments. Read the man pages forstdarg(3) to learn how these work.A common use of variable arguments is to...
(or another processor to which you can port the first solution), you can make calls to the function usingspc_next_varg( )in the normal way. Otherwise, you will need to use theVARARG_CALL_xmacros, wherexis the number of arguments that you will be passing to the function, including ...
I need to create dynamic string by given format(%d,%s,%f,%lf,%c) using variable number of arguments in function. This code gives me an error(main.exe has stopped working): C: #include<stdio.h> #include<stdarg.h> #include<string.h> #include<stdlib.h> char *form(char *format,.....
Hi, I have a C++ prog. which is to be called by either 4 or 5 arguments, i.e. it is always called with 4 arguments however sometimes it might be called with...
