do I need to report this in the bug list?

do I need to report this in the bug list?

[Sridhar]

#include <stdio.h>

int
main(int ac, char **av)
{
    unsigned short int a;
    unsigned short int b;

    printf("Enter a: ");
    scanf("%d", &a);
    printf("a = %d\n\n", a);

    printf("Enter b: ");
    scanf("%d", &b);

    printf("a = %d\n", a);
    printf("b = %d\n", b);
}

Output of the program:
Enter a: 12
a = 12

Enter b: 53
a = 0
b = 53

My problem is that a, becomes zero after the scanf operation of b. And when
I tried to use %h instead of %d the program did even stop for the inputs. I
can avoid the zeroing of if and i declare another short variable between a &
b.

is there any compiler option that I need to enable for compiling this
rightly.

Thanks

Hi Sridhar,

It's not a bug.  Your code is bad.

An "unsigned short int" is not the same as an "int".

You are performing a scanf for an int ("%d"), but you are storing it in an
unsigned short int.  Bad voodoo.

%h is a modifier.  you need to say "%hd".

actually, you should say "%hu" since you're using unsigned short ints.
