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!)

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
