Interview

I have attended the Week-End Accenture interview in Hyd. I was
interviewed for about an hour or so.

Here are the various questions

This interview was conducted for 1 year or more experienced candidates in
C++.

1. Initially he asked me about the project .

2. Then he asked to list the various types of storage classes and
asked to explain the scope & lifetime of each one.

(Auto,Static,Register,Extern,and also mutable(only used for classes))

3. Right shift/Left shift + 1's complement concepts then asked me to
give the output of this:

i = 10;
int j = i >> 10;
cout<<j;

4. Then, difference between

char *str = "Hello";
char arr[] = "Hello";
he started asking whether following statements get complied or not;
arr++; // ERROR..its like a pointer constant
*(arr + 1) = 's';
cout<<arr; // o/p: Hello

5. struct Date
{
int yr;
int day;
int month;
} date1,date2;

date1.yr = 2004;
date1.day = 4;
date1.month = 12;

now how will you initialize date2 (without member by member
assignment)

ans: date2 = date1;

what is the difference between c++ structures & c structures ?

6. Explain Primary Memory, Secondary Memory, Virtual Memory...etc ?

7. What happens when you run a programme. he meant what all the basic
steps that O/S would take??

8. Virtual functions/ Abstract classes/ Pointer functions

9. Asked to write a recursive factorial programme.

10. Then he gave me a problem of inheritance. Asked that how u would
invoke a base class member function using derived class pointer( that
function is not a virtual function & no virtual Base class inheritance)

Is This Answer Correct ?

27 Yes

Answer / abhishek rajan

There four kind of storage classes.
auto(stands for automatic)
static
extern
register

when we declare any variable using auto
eg:
auto int x;
or
int x;
then the scope of the variable will be local.

when we declare any variable using static
eg:
static int x;
then the variable with sustain with that assigned value.

extern is used for the global declaratioin.

register; when this storage class is used
eg:
register int x;
then the value of the variable is going to be stored
directly in the register.
but the register should be free to hold the content of x,
otherwise it will be considered as the variable has the
storage class auto.
