- Q2. Given a chessboard find the maximum number of squares present?
- Ans.
The maximum number of squares on a chessboard is 64.
The chessboard has 64 squares in total.
The number of squares on a chessboard can be calculated using the formula n^2, where n is the number of rows or columns.
In this case, n = 8 (8 rows and 8 columns), so the maximum number of squares is 8^2 = 64.
- Q3. What is C++? Difference between deep and shallow copy?
- Ans.
C++ is a programming language. Deep copy creates a new object and copies all values, while shallow copy creates a reference to the original object.
C++ is a general-purpose programming language
Deep copy creates a new object with its own copy of the data
Shallow copy creates a reference to the original object
Deep copy is safer but can be slower and consume more memory
Shallow copy is faster but can lead to unexpected behav
- Q4. What is pre initialization ?
- Ans.
Pre initialization refers to the process of initializing variables or objects before they are used in a program.
Pre initialization helps avoid errors or unexpected behavior caused by using uninitialized variables.
It is a good practice to pre initialize variables with default values.
Pre initialization can be done using constructors, default values, or initialization blocks.
Example: int count = 0; initializes the variabl
- Q5. Reverse a linked list with and without using Recursion
- Ans.
Reverse a linked list with and without using Recursion
Iterative approach: Use three pointers to reverse the links between nodes
Recursive approach: Recursively reverse the rest of the list and then fix the links
- Q6. Copy constructor?
- Q7. Different types of polymorphism, the diamond problem, and how can it be avoided?
- Ans.
Polymorphism refers to the ability of an object to take on many forms. The diamond problem occurs in multiple inheritance.
Polymorphism can be achieved through method overloading and method overriding.
Method overloading allows multiple methods with the same name but different parameters.
Method overriding occurs when a subclass provides a specific implementation of a method already defined in its superclass.
The diamond p...
- Q8. Questions about Virtual
- Q9. Template classes
- Q10. Write a program for an operator(=) such that it behaves differently for integer and character
- Ans.
The program should differentiate between integers and characters when using the assignment operator (=).
Check the data type of the variable before assigning a value.
Use conditional statements to perform different actions based on the data type.
For integers, assign the value directly. For characters, convert the character to its ASCII value and assign it.
- Q11. Given an array, sort the zeroes from non zeros for example Input: 1 2 0 0 7 4 42 0 0 0 6 Output: 1 2 7 4 42 6 0 0 0 0 0
- Ans.
Sort an array by moving all zeroes to the end.
Iterate through the array and move all non-zero elements to the front.
Count the number of zeroes encountered and append them at the end of the array.
Use two pointers to swap elements and maintain the order.
- Q12. Class hierarchy, List the number of VTables created
- Ans.
The number of VTables created in a class hierarchy depends on the number of virtual functions and the number of derived classes.
VTables are used in object-oriented programming languages to implement dynamic dispatch.
Each class with at least one virtual function has its own VTable.
Derived classes inherit the VTable of their base class and add their own entries for any additional virtual functions.
The total number of VTa...
- Q13. When to use List and Vector of Standard Template Library ?
- Ans.
List is preferred when frequent insertion and deletion is required. Vector is preferred when random access is required.
List is implemented as a doubly-linked list, allowing for efficient insertion and deletion at any position.
Vector is implemented as a dynamic array, allowing for efficient random access.
Use List when the number of elements is expected to change frequently and the order of elements matters less.
Use Vect...

- Q5. Difference between deep and shallow copy?
- Ans.
Deep copy creates a new object with a new memory address, while shallow copy creates a new reference to the same memory address.

Unique key is used to ensure that no two rows in a table have the same values in a column or set of columns.
Primary key can be a singl...
- Q12. Can unique key be a primary key?
- Ans.
Yes, a unique key can be a primary key.
A primary key is a unique identifier for a record in a table.
