         Interview

I  have attended the Week-End Accenture interview in Hyd. (I am afraid, its not for freshers). I was
    interviewed for about an hour or so.Here are the various questions:-This interview was conducted 
    for 1 year or more exp. guys in C++.

1.  Firstly he asked me about the project and i was thoroughly grilled.
   
   

2. Then he asked to list the various types of storage classes and asked me 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 b/w
     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;
   
   diff. b/w c++ structures & c structures
   
   

6. Explain Primary Memory, Secondary Memory, Virtual Memory...etc 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 me to write a recursive factorial prog.
   
   

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