Printf is a special case where it takes the variable number of arguments and print them on stdio based on the format specifier. Following is the syntax/prototype -

int printf (__const char *__restrict __format, ...);

Prototype of printf function is:

int printf( const char *format ,?)

In this the Second parameter: '?' (Three continuous dots) are known as called ellipsis which indicates the variable number of arguments.
