Answer :

30,20,10

Explanation:

'{' introduces new block and thus new scope. In the
innermost block i is declared as,

const volatile unsigned

which is a valid declaration. i is assumed of type int. So
printf prints 30. In the next block, i has value 20 and so
printf prints 20. In the outermost block, i is declared as
extern, so no storage space is allocated for it. After
compilation is over the linker resolves it to global
variable i (since it is the only variable visible there). So
it prints i's value as 10.

what is the output of the below program & why ? #include<stdio.h> void main() { int a=10,b=20,c=30; printf("%d",scanf("%d%d%d",&a,&b,&c)); }

There is a lucky draw held every day. if there is a winning number eg 1876,then all possible numbers like 1867,1687,1768 etc are the numbers that match irrespective of the position of the digit. Thus all these numbers qualify fr the lucky draw prize Assume there is no zero digit in any numbers. write a program to show all the possible winning numbers if a "winning number"is passed as an arguments to the function.
