Use of Variable Argument Lists
Explore how to implement variable argument lists in C functions for flexible inputs. Understand how to use va_start, va_arg, and va_list macros to access arguments dynamically. This lesson helps you write functions like findmax that accept varying numbers of parameters effectively.

You can pass a variable number of arguments to functions, like printf( ) and scanf( ). We can also write functions that receive different numbers of arguments in different calls.
Example program
Here, we propose to write a function call, findmax( ), that finds the maximum out of the numbers passed to it. To do this, we need to use three macros: va_start, ...
