if(a,b,x,y)

    main(){

  int a= 0;int b = 20;char x =1;char y =10;

  if(a,b,x,y)

        printf("hello");

 }

Answer:

hello

Explanation:

The comma operator has associativity from left to right. Only the rightmost value is returned and the other values are evaluated and ignored. Thus the value of last variable y is returned to check in if. Since it is a non zero value if becomes true so, "hello" will be printed.
