Hi
I went to company called "intense" for attending interview. But, we were told to attempt a written test. It had 2 sections.
Section 'A' had 2 programs.
1) Write a Program to remove the duplicate elements from an array
2)1) Write a Program to count the number of elements in a stack

Section 'B' had 25 multiple questions, most of them are from test ur C skills

1) main()
{
printf("%p", main);
}

2) main()
{
int i=5;
printf("%d%d%d%d%d",i++, i--, i, ++i, --i );
}

3) main()
{
printf("%d%c");
}

4)
main()
{
int i = 3;
while(i--)
{
i =100;
printf("%d",i );
}
}

5) struct xx
{
int a=3;
char b[4]= "this";
};
main()
{
struct xx s;
printf("%d%s", s.a, s.b);
}

6) main()
{
register i =10;
char b[3] = "hai";
printf("%d%s",i, b );
}
