Ellipsis and Variadic

In C, when a function is called, the arguments are typically placed onto the stack, a region of memory. The function retrieves these arguments from the stack based on the function’s known parameter list. But when the number of arguments is variable, the function needs a way to access these “extra” arguments from the stack.

This is where the stdarg.h functions come into play. They allow access to arguments by manipulating the memory address of the current argument to point to the next one. Let’s talk about ellipsis (…) and how it is used in C in the following article.
