C++ | How to show output | Lecture 10

How to show output in C Plus Plus?

Here you will come to know how to show output in C++. Here a special command is used

cout

Pattern :

cout << "It is Samee Articles: Quality Written Codes Blog. It is How to show output article." ;

termination is very important. don't forget it.
thanks.

C++ | Beginning of Arrays | Lecture 7

Lecture 7:

Today we 'll discuss about Arrays in C++.
Array is a data structure, which allows us to collect same size and type of values in single variable. And if you need to call any specific value within array. You need to call its position. Here you will learn that how can we play will array in C++.

C++ | Return Value in Function | Lecture 6

Lecture # 6:

Here you will learn that how to return value in function in C++ programming?
It is a very useful way and important way. You will use it in your programming many times. It works with user define functions. Let's try it.
Here we take dog year example.

C++ | Arguments In Functions | Lecture 5

Default arguments in functions allow you to call specific arguments within the specific function.
Here we defined two functions.

pow() And rand()

And we use them to get the specific value.

C++ | Beginning Functions > Using math library functions | Lecture 4

 Using Math Library Beginning Functions:

Here you will learn about Math Library Beginning Functions. Like

1. Cos
2. Sin
3. Tan
4. Sqrt
5. Pow
6. Log
7. And More

But here, I'll just discuss one function that is

sqrt function >> Square root function >> text with the √ symbol

In below given code, you will learn that
1st) You should add

#include <cmath>

into the header. It is mathematics library in C Plus Plus, in which you can find all important math functions.

double num2;
num2 = sqrt (num1);

Here I am taking the square root of num1 variable. likewise, you just need to try same functionality to all math type functions.

C++ | How to get user input in C++? Lecture 3

How to get user input in C++?
Here you need to use IOStream function

CIn >>

CIn is used to get input from the user but before it, You need to declare a variable in which you can serve your user value.

Note: "using namespace std" is important to add. It is used to add standard functions.

If you are thinking about

<<

So it is used as concatenation like in PHP dot operator performs

    return 0;

C++ | Modify variable and replace its values | Lecture 2

Variable:

Variable is certain type of variable which is liable to vary and change for specific purpose and according to its range.

Types of Variable:

Modify Variable And Replace Its Value:

In Lecture 2 you will learn about variable modification and replacement.
Once you define a variable you can easily use that for print out your data. as

mynumber = 55;  
cout << "My Number is = " << mynumber << endl;  

If you are thinking about

endl

endl (End Line), It is used to break the line.
As you know, why do we use

system("pause");

So we can stop our function anywhere and anytime. 
If you define a variable and show its value.
Again you replace another value to this same variable and again show its value. So, now its value will be changed because you have replaced its value. C++ or any other language always prefer to latest value.
You can also use addition, multiply or any mathematics rules for variables but you need to see its type.
Variable type is very important to describe. Variable is defined according to its range.

How to show output: Basic Syntax and Function: Lecture 1

How to Show Output And Basic Syntax and Function:

In C++ (C Plus Plus), we need to include C++ Libraries then we start body parts. If we need to describe user define functions then we'll describe that between head and body.

IOStream

This library is used for (Input & Output Stream). Because we may need to use many input-output built-in functions within body parts.

int main()

The main body starts here. You need to define your main executed code here.

Cout << "Welcome to Quality Written Codes.";

Cout is used for output the value.  We'll write output value within single or double quotes. It is like Echo Function in PHP

Note: Every line will be terminated with semi-colon ( ; ) is called "Terminator" as PHP

There are two ways to write comments within C++ Code.

#include <iostream> //C++ Library

#include <iostream> /*C++ Library */

1. You can add comments with two slashes " // "
2. You can also comment with "/* Quality Written Codes */" Asterisk Slash.

Note: These two methods are same as PHP comment system

Here you will know, How to pause system?

system("Pause");

You need to use this function, where you need to pause system.

Return 0;

It will null to 1st function or execute the function.

Learn Its basics and ask the question about it.
