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,.....
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...

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...
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...
Those types that change their sizes on a 64-bit system, i.e. memsize-types, are dangerous for the functions with the variable number of arguments. PVS-Studio static analyzer warns the programmer about such types with the help of the V111 diagnostic warning....
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...
