C++ is an extension of C with object-oriented programming features.
C++ supports object-oriented programming while C does not.
C++ has classes and templates while C does not.
C++ has better support for exception handling than C.
C++ has a standard library while C does not.

Arrays are contiguous blocks of memory while linked lists are made up of nodes that point to the next node.
Arrays have fixed size while linked lists can grow dynamically.
Insertion and deletion are faster in linked lists than in arrays.
Arrays have better cache locality while linked lists have better memory utilization.
Arrays are accessed using indices while linked lists are accessed using pointers.
Examples of arrays inc...
Data abstraction is the process of hiding implementation details and showing only necessary information.
Abstraction is achieved through abstract classes and interfaces.
It helps in reducing complexity and increasing efficiency.
Example: abstract class Shape with abstract method draw() implemented by its subclasses like Circle and Rectangle.
TCP/IP is a protocol used for communication between devices on the internet. OSI model is a conceptual framework for network communication.
TCP/IP is a suite of protocols that governs communication between devices on the internet.
OSI model is a conceptual framework that divides network communication into seven layers.
TCP/IP is based on a four-layer model, which includes the application, transport, internet, and network ...
Program counter is a register that stores the memory address of the next instruction to be executed by the processor.
Program counter is also known as instruction pointer.
It is a part of the processor's control unit.
The value of program counter is incremented after each instruction is executed.
If a program counter is corrupted, the processor may execute incorrect instructions.
Example: If the program counter is pointing ...
A program to reverse a given string.
Create an empty string to store the reversed string.
Iterate through the original string from end to start.
Append each character to the empty string.
Return the reversed string.
Recursion is a technique where a function calls itself to solve a problem. WAP for recursion is to write a program using recursion.
Recursion is used to solve problems that can be broken down into smaller sub-problems.
The base case is the condition where the function stops calling itself.
The recursive case is where the function calls itself with a smaller input.
Example: Factorial of a number can be calculated using recu...
A microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit.
Microprocessors are used in various electronic devices such as computers, smartphones, and gaming consoles.
Register names include program counter (PC), accumulator (ACC), general-purpose registers (GPR), and memory address register (MAR).
Registers are used to store data and instructions t...
SQL commands are used to interact with databases and manipulate data.
SELECT: retrieve data from a database
INSERT: add new data to a database
UPDATE: modify existing data in a database
DELETE: remove data from a database
CREATE: create a new database or table
ALTER: modify the structure of a database or table
DROP: delete a database or table
JOIN: combine data from multiple tables
GROUP BY: group data based on a specific colum
SQL query to join two tables
Use JOIN keyword to combine two tables based on a common column
Specify the columns to be selected using SELECT keyword
Use ON keyword to specify the common column between two tables
Pointers are variables that store memory addresses. Heap is a region of memory used for dynamic memory allocation.
Pointers are used to access memory directly
Heap is used for dynamic memory allocation
Pointers can be used to create data structures like linked lists
Heap memory must be manually managed to avoid memory leaks
The process of converting Example.c file to Example.exe involves several steps.
Preprocessing: includes header file inclusion, macro expansion, and conditional compilation
Compilation: converts source code to object code
Linking: combines object code with libraries to create executable file
Debugging: identifying and fixing errors in code
Optimization: improving performance of executable file
