Variadic Function

A variadic function is one which accepts a variable number of input arguments. In C we can write functions that are variadic. Sometimes this may be useful.

Note we have to #include <stdarg.h> in order to use the handful of functions necessary to work with the argument list.

Note we have already seen a sort of variadic function, which is the main() function, which as we know can accept a variable number of input arguments when the program is started at the command line.

We are finally done with functions. Test your knowledge in the exercises that follow. Next up on our journey, we’ll learn about more complex data structures and types.
