In the realm of programming, the ellipsis, denoted by three consecutive periods (‘…’), holds a significant role. It serves as a versatile placeholder, representing various concepts and behaviors depending on its context. Variadic Functions: The ellipsis is commonly used in function signatures to indicate that the function accepts a variable number of arguments. For example, in C/C++, the `printf` function takes a format string followed by an arbitrary number of arguments: “`c printf(“Hello, %s!n”, name); “` Variadic Templates: In C++, the ellipsis can be employed in template definitions to create variadic templates. These templates allow functions and classes to operate on an arbitrary number of types: “`cpp template void print_all(Args… args) { for (auto arg : args) { std::cout
