20+ Kong Interview Questions and Answers

Polymorphism is the ability of a function to behave differently based on the object it is called with. Virtual functions allow dynamic binding.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• Virtual functions are functions in a base class that are overridden in derived classes.

• To implement a compiler, you would need to handle polymorphism and virtual functions for proper function resolution.

A function template is a generic function that can work with any data type. When a template is executed, the compiler generates a specific function for each data type used.

• Function template allows writing a single function that can work with different data types.

• When a template is executed, the compiler generates a specific function for each data type used.

• Templates are a powerful feature in C++ that enable generic programming.

• Example: template <typename T> void print(T value...read more

Memory allocation in struct is not continuous because of alignment requirements and padding for efficient memory access.

• Struct variables may contain different data types with different memory alignment requirements

• Padding is added to ensure each variable is aligned properly for efficient memory access

• Example: struct with int, char, and double variables may have padding between them for alignment

Implement a custom malloc function to allocate memory of 16 bytes with starting address divisible by 16.

• Allocate memory using malloc function

• Adjust the starting address to be divisible by 16

• Return the adjusted memory address

The apti, coding test, and entire selection procedure were challenging but well-structured.

• The aptitude test covered a wide range of topics and required logical thinking.

• The coding test involved solving complex problems using programming languages.

• The selection procedure included multiple rounds of interviews and assessments.

• The overall process was rigorous but fair, allowing candidates to showcase their skills and abilities.

The maximum stack memory available cannot be determined using the given data structure.

• The maximum stack memory available depends on the hardware and operating system.

• It is not possible to determine the maximum stack memory based on the given data structure alone.

• To determine the maximum stack memory, one would need to consider the hardware limitations and the operating system's stack size limit.

• The data structure provided does not contain information about the maximum stack ...read more

The solution to determine whether a number is even or odd is to use the modulus operator with 2.

• Use the modulus operator (%) to find the remainder when the number is divided by 2.

• If the remainder is 0, the number is even. Otherwise, it is odd.

• Example: 7 % 2 = 1, so 7 is an odd number.

• Example: 10 % 2 = 0, so 10 is an even number.

Sockets, pipes, and inter-process communication are mechanisms used for communication between processes.

• Sockets are endpoints for sending and receiving data across a network. They enable communication between processes running on different machines.

• Pipes are a form of inter-process communication that allows communication between processes running on the same machine. They provide a unidirectional flow of data.

• Inter-process communication (IPC) refers to various methods used by...read more

Function pointers are used to pass functions as arguments to other functions, allowing for dynamic behavior and flexibility in programming.

• Function pointers can be used for callback functions in event handling systems.

• They can be used to implement polymorphism in object-oriented programming.

• Function pointers are commonly used in sorting algorithms to specify custom comparison functions.

Process scheduling manages execution of processes, while thread scheduling manages execution of threads within a process.

• Process scheduling involves allocating CPU time to different processes, while thread scheduling involves allocating CPU time to different threads within a process.

• Process scheduling is typically handled by the operating system, while thread scheduling can be managed by the application itself.

• Examples of process scheduling algorithms include Round Robin, Fir...read more

Little endian and big endian are two ways of storing multi-byte data types in computer memory.

• Little endian: least significant byte is stored first

• Big endian: most significant byte is stored first

• Example: In little endian, the number 0x1234 is stored as 0x34 0x12

• Example: In big endian, the number 0x1234 is stored as 0x12 0x34

AI content writing focuses on generating engaging and optimized content for online platforms, while academic writing is more formal and research-based.

• AI content writing uses algorithms to create content that is tailored for online audiences and optimized for search engines.

• Academic writing is more formal, structured, and research-based, focusing on presenting arguments and supporting evidence.

• AI content writing may prioritize readability, SEO, and engagement metrics, while a...read more
