Subex Systems Paper

This is the Subex Azure placement paper. My advice is that if you are not comfortable with C, don’t write Subex (don’t waste ur time ok!)
Test of location: [shal]Trivandrum[/shal]

Pattern
C programming 20 questions (30 minutes)
The following are the question i remembered. Hope it will give a clear cut idea about Subex.

1.struct
{
unsigned int is_keyword:1;
unsigned int is_extern:1;
unsigned int is_static:1;
}flag;
printf("%p",&flag is_static);
whts is the o/p?
ans:

2.1.struct
{
unsigned int is_keyword:1;
unsigned int is_extern:1;
unsigned int is_static:1;
}flag;
main()
{
printf("%d",sizeof(flag));
o/p?

3.main(int argc,char argv[])
{
int i=10,j=10;
const int *ptr;
int *const ptr1=&j;
ptr=&i;
++(*ptr);
ptr1=&i;
is it compile?

4.union
{
int ival;
char ival;
}u;
main()
{
u={1,'2'};
printf("%d",sizeof(u));
}
o/p?

5.int foo(void)
{
char *p;
int i;
if(i&&(*p=10))
return 1;
else
return 0;
calling the function foo,what happened?

6.int i=260;
float f=12.2;
char c='a';
char *ptr1,*ptr2,*ptr3;
ptr1=(char *)&i;
ptr2=(char *)&f;
ptr3=(char *)&c;
printf("%d %d %d",*ptr1,*ptr2,*ptr3);
o/p?

7.int main(int argc,char **argv)
{
int *p;
p=malloc(10*sizeof(int i));
realloc(p,0);
/*(i) */
return 0;
whts tht state of (i)?

after this we had a programming question.

my question is tht write a pgm to count the occurrence of following C keywords in a file and calculate the sum?
1.int
2.char
3.static
4.struct
5.union
6.return

Hey guys, dont upset ..be confident.prepare well (means from a to z of C)…Then u can simply get it
