some functions allow to pass any number of arguments such as
printf ,scanf etc.

Answer / pavan mustyala

Check out the below link!!! it gives a nice insight of this
concept.

http://www.cprogramming.com/tutorial/c/lesson17.html

Anyways, this is about a function accepting variable number
of arguments i.e., at different places of calling that
function, number of arguments can differ.

Example:
int Some_func( int param1, ... ); is the declaration to it.

the 3 dots (called ellipsis) tells the compiller that it
accepts variable number of arguments.

int main() { int x=10; printf("x=%d, count of earlier print=%d", x,printf("x=%d, y=%d",x,--x)); getch(); } ================================================== returns error>> ld returned 1 exit status =================================================== Does it have something to do with printf() inside another printf().
