Can a function return more than one value in C? -

-

i'm beginner in c. heard function in c cannot return more 1 value, not case in program; it's returning more 1 value , code running fine. please explain.

#include<stdio.h> int main () {     int a=10,b=9;     return a,b; }

function can return single value . 

 #include<stdio.h>  int main () {   int a=10,b=9;   return a,b;  }

when returning that. here comma (,). operator work. return last value list.
