in this class we are only conversation about this course and more how this course run and,
how it work and more about

but Write First "Hello World" without understanding only testing how it work and Hello World" Working and not
*/

#include <iostream> // <iostream> is a header file in this file has already defined same code what work cin, cout, print, this main using for input output, if you want more knowledge about this visit google and write a header file name only and hit Enter you got your and ware and more about header file

Topic 1.1 What is C++

1. C++ is a statically-typed, Free-form, (Usually) Compiled, multi-paradigm, Intermediate-level general-purpose middle-level programming language.
  • Statically-Typed: You need to follow the C++ Sentence. If you do not follow the sentence you get an error.
  • Free-Form: C++ does not have any form you can write any type and where only follow Sentence.
  • Compiled: C++ is using after compiled. (same time note need to compile for run the program)
  • Multi-Paradigm: you can solve C++ in many types (Many typed for solve problem in C++)
  • Intermediate-Level general-purpose Middle-level Programming Language.

2. C++ is a general-purpose programing language based on C. It was developed by Bjarne Stroustrup in 1979.

3. many of today's Operating Systems, Systems Drivers, Browser, and games use C++ as their core Language. This makes C++ one of the most popular Languages.

4. Since it is an enhanced/extended version of the C programming language. C and C++ are often denoted together as C/C++. (C and C++ are very similar programming Language).


Topic 1.2 Why C++?

1. C++ is irreplaceable.
2. You lean the internal architecture of a computer.
3. C++ job opportunities and salary.


Topic 1.3 Features of C+

C++ is fast.
C++ is Statically Typed
C++ is a multi-paradigm programming Language (We can solve it by many typed)
An object-oriented programming language with C++ (Not Completely Like JAVA)
 Power of standard library (Standard Template Library - STL)


Topic 1.4 What C++ Compiler Does (Basic) & How Compiler Works

How Compiler Works

Basic Structure of hello Word in C++


#Include

#include is a way of including a standard or user-defined file in the program and is mostly written at the beginning of any C/C++ program.
The process of importing such files that might be system-defined or user-defined is known as File Inclusion. This type of per-processor directive tells the compiler to include a file in the source code program.


<iostream>

It's called Header file. In Header file has already defined same works.
For Example the <iostream> has defined Work of "Cin" "Cout" and more.

2. MacBook Air 2017

Macbook Air 2017 is best laptop under 50000 INR for all programming

This is the best favorite laptop under 50,000 INR. I know it's the same old best this is the amazing performance in 2020 but all think is not good just like Display it's not good if you're doing your very much work for Color Correction and it's very important for you so this laptop not for you. but in the performance, as you all know the apple make the best product it's has 10-12 hours Normal Web-browsing


Good Point's for MacBook Air 207

Why I'm not using MacBook Air

  • Repairing Cost is very high
  • The display is not FHD (use another FHD monitor for display)

Class 01

Learn about C++ and what we get in this course and writer First "Hello World" in C++


How To Write Hello World in C++ Programming Language

  

How To Write Hello World in C++ Programming Language


How To Write Hello World in C++ Programming Language
C++ Hello World with all problems

So we are writing Hello World in C++ programming language. I'm using Windows as an Operating System and IDE VSCode and complier are Mingw.

The Hello Word Programme

#include<iostream>
using namespace std;
int main()
{
    cout<<"Hello Word";
    return 0;
}


Questions for This Program

  1. What is #include, why we use
  2. what is <iostream> and why we use
  3. what is the namespace and why we use
  4. What is std and why use
  5. int main
  6. what is the main
  7. What is cout
  8. what is return 
  9. and why we use 0 in return 

ANSWER FOR THOSE QUESTIONS

1. #include
When we are writing a C++ Program. we need to add some Header file. So #include is used to add the Header file to the program. In Header file has already defined the function we are using in the program.

Example: I'm using <iostream>  Header File by #include because in this file has already defined many Function and Variables so don't need to define any functions and think more
we are using Header file for a done job fast and easily

2. <iostream>
It's is a Header file using for taking input and output from user and program so we used this Header file but in the next tutorial,
we are using more header files in our program

What is CPU


What is CPU | Types of CPU (2020)


So we are covering this article in the same topics
  1. What is CPU
  2. Types of CPU
  3. Main Functions of CPU

What is CPU

CPU Full name is Central Processing Unit. We can call them the mind of Computers just like a human has a mind to identity Thinks(Objects) and calculate any this we are seeing, hearing, and felling, The Same work is doing a CPU (Central Processing Unit) on a computer.

For more understand we can think the computer is a human being body and CPU is a part of the body(Mind).

When we are doing any task by phone, tab, Laptop, and more all work done by CPU (Processer) now you reading this article this processed by your CPU when you open your browser and search anything it's done by When you are playing PUBG the CPU is playing the game and giving you joy.

Each Process doing, done by CPU (Where it use)

More about CPU by Books
A central processing unit also called a central processor or the main processor is the electronic circuitry within a computer that executes instructions that make up a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output operations specified by the instructions in the program.

If want to learn more about CPU and get more deep knowledge about CPU you can visit Wikipedia


Types of cpu (Central processing unit)

TYPES OF CPU

Different Persone Purchasing Different Different CPU according to Different Different work.

Just like if I want to build a pc for gaming so I need a Good Cores CPU but more invest in GPU (Graphics processing unit) But I need a Dual Cares CPU for Better Experience.

 In Productive work, I need a very good CPU Just like Photoshop, Video Editing, and heavier Software 

 Now I'm Using AMD Ryzen 7 2700x CPU (8 Cores | 16 thread) Because I'm Editing my 4k Video on this CPU So I Need Good Processer

 Light Test: If I'm Using PC For light test So I Don't need heavy CPU

So CPU Divided into Three Types of CPU

1. Single Cores CPU

This Types of CPU are very older Types Computer CPU. Those CPU has only Single core available for Its low-end CPU

In 2020-21 It's Impossible Task  to find these types CPU Now

 Just Like we all know that Nokia 1110 is an old phone but not findable in 2020-21 So just for knowledge it very old Genracan of Computer CPU

2.  Dual-Core CPUs 

This CPU has Two core and two threads in single CPU

 This CPU 2x faster than Single Cores CPU. 
1 Dual-Core CPU = 2 Single-Core CPU

 In 2020-21 it's good for web Browsing and more light work we can do light Photo editing in Photoshop and Video editing by a dual-core CPU

 My First Laptop has AMD A6 Dual-core CPU and I can do 720 Video editing, Smooth Photo editing nad good web browsing by Dual-Core CPU

3.  Quad-Core CPU

This Type CPU has Two and more core and threads 

If you visit on the market and you get Quad Core CPU from 10,000. The market has this type of CPU. Single and Dual-Core CPU Not Desing by any company in 2020. Those types of the CPU market gone now
Types of CPU
  1. Singl-Core CPU has one core only
  2. Dual-Core CPU has two core
  3. Quad-Core CPU has Two and more Core

Thank you so much for reading this article. If you have any Problem & Suggestion Please Comment because it's very helpful for improving myself
