Variable arguments are used by functions in the printf family (printf, fprintf, etc) and others to allow a function to be called with a different number of arguments each time, hence the name varargs. To implement functions using the variable arguments feature, use #include <stdarg.h>. To ...

Usually the functions defined in C/C++ take constant number of arguments which are decided while declaring the functions. Sometimes we do need the functions that can accept variable number of arguments, Printf() function is a great example of such functions. Let's see how these functions work ...
The vprintf function in C performs formatted output like printf, but takes a va_list instead of variable arguments. It's declared in stdarg.h and follows the same format specifier rules as printf. This function is particularly useful when creating wrapper functions around printf with variable ...
