return function

Hi,I am confused and need the answer of the question mentioned below soon.
return(x,y) is valid?
Can a return() function return more than one value within one statement.

Expand|Select|Wrap|Line Numbers
  1. #include<stdio.h>
  2. #include<iostream.h>
  3. int sum(int i,int j);
  4. main()
  5. {
  6.  int a,b,k,l;
  7.  char c;
  8.  a=3,b=4;
  9.  k= sum(a,b);
  10.  l=sum(a,b);
  11.  printf("%d %d",k,l);
  12.  c= getchar();
  13.  return 0;    
  14. }     
  16. int sum(int i,int j)
  17. {
  18.     int kk,ll;
  19.     kk = i + j;
  20.     ll = i * j;
  21.     return(kk,ll);
  22. }
Earlier I thought compiler should give a compile time error but instead it executed the code and retun 12 12 as the answer.WHY????????

, is an operator, just like +, ||, ==, etc. So returning kk, ll actually returns (I think) ll, as the comma operator returns the rightmost expression. Of course, the function isn't returning both kk and ll, it is only returning 1, so there is no reason to ever use the comma operator in a return statement.

very basic and easy.
'return' returns only one variable. no more than that.
you can return an array, vector, int,long.........
anything but only one variable.
