Docker is a platform for developing, shipping, and running applications in containers.
Docker allows applications to be isolated in containers, making them portable and easy to deploy across different environments.
Containers share the host OS kernel but run as isolated processes, providing lightweight and efficient virtualization.
Docker simplifies the process of packaging applications and their dependencies, ensuring co...
Database normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
Database normalization involves breaking down data into smaller, more manageable tables and defining relationships between them.
It helps in reducing data redundancy, improving data integrity, and making the database more efficient.
For example, in a project I worked on, we normalized the database by spl...

VLSI design cycle is the process of creating integrated circuits by going through various stages from design to fabrication.
VLSI design cycle involves stages like specification, design, verification, synthesis, and fabrication.
It starts with defining the requirements and specifications of the integrated circuit.
Design phase includes logic design, circuit design, and physical design.
Verification ensures that the design ...
I applied via Approached by Company and was interviewed in Nov 2023. There were 3 interview rounds.
Function to dynamically allocate memory and write data to a memory location, returning the address details.
Use malloc() or calloc() to dynamically allocate memory
Use memcpy() or strcpy() to write data to the allocated memory
Return the address details where data is present
Memory management involves allocating and deallocating memory efficiently, while mapping involves associating memory addresses with physical locations.
Memory management is crucial for optimizing performance and preventing memory leaks.
Mapping involves translating virtual memory addresses to physical memory locations.
Different scenarios may require different memory management strategies, such as stack allocation vs heap...
Program to find length of bits assigned in memory using recursion.
Define a recursive function to count the bits in memory
Base case: if input is 0, return 0
Recursive case: return 1 + function(input / 2)
Volatile keyword prevents compiler optimization by telling the compiler that the variable's value can change unexpectedly.
Volatile keyword is used to indicate that a variable may be changed unexpectedly, such as in the case of hardware registers.
When initializing GPIO pins, using volatile keyword ensures that the compiler does not optimize away the initialization code.
Without volatile keyword, the compiler may optimize...
Unions in C/C++ can be used for bit assignments by allowing multiple variables to share the same memory location.
Unions allow different data types to be stored in the same memory location, which can be useful for bit manipulation.
By defining a union with multiple variables of different data types, you can access the same memory location using different variable names.
For example, you can use a union to access individua...
static const is used to declare constants that are known at compile time and cannot be modified
static const int MAX_SIZE = 100; // declaring a constant integer
static const double PI = 3.14159; // declaring a constant double
static const char* MESSAGE = "Hello, World!"; // declaring a constant string
Program to find the sum of all the digits in a number.
Iterate through each digit in the number and add them together.
Convert the number to a string to easily access each digit.
Use modulo operator to extract each digit from the number.
Handle negative numbers by taking the absolute value before processing.
Check if a linked list is circular, if not reverse it.
Create two pointers, one moving at double the speed of the other to detect a cycle
If a cycle is detected, the list is circular. If not, reverse the list by changing the pointers' directions

Various data filtering techniques include sorting, grouping, aggregating, and applying filters based on specific criteria.
Sorting: arranging data in a specific order, such as ascending or descending
Grouping: categorizing data into distinct groups based on common attributes
Aggregating: combining multiple data points into a single value, such as summing or averaging
Filtering: selecting only the data that meets certain cr
