@all sorry i give wrong explanation by mistake..:P :P
printf("") returns no if characters.. in this case returns 0 . which is
assigned to ch
so in ch 0 is stored and 0 is the ascii value of null character
when we using ch in --- if (ch) --> it will reduce to if(0) -- as 0 is the
ascii value of null character
so the output "it doesn't matter"
