Even an interviewee with only passing knowledge should write something similar to this, mostly likely involving a helper class:. It should compare class A and B and return false when they are different classes and true if they are the same class.

Although you can call an inline function from within itself, the compiler may not generate inline code since the compiler cannot determine the depth of recursion at compile time. A compiler with a good optimizer can inline recursive calls till some depth fixed at compile-time say three or five recursive calls , and insert non-recursive calls at compile time for cases when the actual depth gets exceeded at run time.

This program will terminate abnormally. The class A destructor will throw another exception during the exception handling, which will cause program to crash.

This question is testing if developer has experience working with exceptions. The method should be cross-platform compatible and not depend on sizeof int, bool, string. Create another class which has all the members of Something in the same order, but has additional public method which returns the value. Your replica Something class should look like:. Note: If it turns out that the alignment of the external library is mismatched to your code, you can resolve this using pragma pack.

Implement a void function F that takes pointers to two arrays of integers A and B and a size N as parameters. It then populates B where B[i] is the product of all A[j] where j! This will work for the given example, but when you add a 0 into input array A, the program will crash because of division by zero. The correct answer should take that edge case into account and look like this:.

The presented solution above has a Big O complexity of O N. While there are simpler solutions available ones that would ignore the need to take 0 into account , that simplicity has a price of complexity, generally running significantly slower.

So when you have a class class A which inherits from 2 parents B and C , both of which share a parent class D , as demonstrated below:. To fix this you need to change the declarations of classes C and B to be virtual, as follows:. This question is testing pointer arithmetic knowledge, and the magic behind square brackets with pointers.

If you said , you would have been correct if i had been declared as an int. However, since i was declared as an unsigned char , the corrct answer is that this code will result in an infinite loop. However, since i is an unsigned char , it is rerepsented by an 8-bit value which, after reaching , will overflow so it will go back to 0 and the loop will therefore go on forever. A class that specifies the life and scope of its variables and functions is called a storage class.
