The memory layout of C programs refers to how variables and data structures are organized in memory.
C programs typically have four main sections in memory: code, data, heap, and stack.
The code section contains the compiled program instructions.
The data section stores global and static variables.
The heap is used for dynamic memory allocation.
The stack is used for function calls and local variables.
Pointers in C hold mem...

Data structures are fundamental concepts in software engineering that organize and store data efficiently.
Arrays: Simple and efficient for storing and accessing elements.
Linked Lists: Dynamic and flexible, efficient for insertion and deletion.
Stacks: LIFO structure, useful for managing function calls and undo operations.
Queues: FIFO structure, ideal for managing tasks and scheduling.
Trees: Hierarchical structure, used ...
The difference is that 'int arr[5]' creates an array on the stack, while 'malloc(5*sizeof(int))' allocates memory on the heap.
int arr[5] creates an array of 5 integers on the stack, which is a fixed-size memory allocation.
malloc(5*sizeof(int)) dynamically allocates memory on the heap, allowing for variable-size memory allocation.
The memory allocated with malloc must be explicitly freed with free() to avoid memory leaks

TELNET is a network protocol used to establish a connection with a remote computer over a network.
TELNET stands for Telecommunication Network.
It allows a user to log in to a remote computer and execute commands as if they were directly connected to that computer.
TELNET operates on port 23.
It is not secure as the data is transmitted in plain text.
SSH (Secure Shell) is a more secure alternative to TELNET.
TELNET is insecure, while SSH is secure for remote access to servers.
TELNET sends data in plain text, while SSH encrypts data for secure communication
SSH uses public-key cryptography for authentication, TELNET does not
SSH provides secure remote access to servers, TELNET does not prioritize security
TELNET operates on port 23, while SSH operates on port 22

A volatile variable is a variable that can be modified by multiple threads simultaneously.
Volatile variables are used in multithreading to ensure visibility of changes made by one thread to other threads.
They are not cached in thread's local memory, but always read from main memory.
They are typically used for flags or status variables that are accessed by multiple threads.
Example: 'volatile boolean flag = true;'
Multithreading in Java allows multiple threads to execute concurrently, improving performance and responsiveness.
Multithreading allows multiple threads to run concurrently within a single process.
