main(){ int a= 0;int b = 20;char x =1;char y =10; if(a,b,x,y) ..

Answer / susie

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.
