syntax -
z-index : x(value in positive or negative );

Code -

1.If we take the value of z index in negative 

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<style>
#index{
position: absolute;
top: 0;
z-index: -3;
}
</style>
</head>
<body>
<img id="index" src="img/A1.png" alt="">
<p class="" style="color: wheat;">
In display property if we apply inline-block property on it we can be set their width and height and element was set next to a element in line it not take extra space so in easy word it is work as both block element who's width and height can be changed and inline which do not take extra space In this display property line will take whole block of line or other word the line will take complete one line space if there is element is present or not it will take whole line as a block . line it not take extra space so in easy word it is work as both block element who's width and height can be changed and inline which do not take extra space In this display property line will take whole block of line or other word the line will take complete

Funcation in c++ programming example in detail

Friend Funcation- 1. Adding to complex number in friend function #include<iostream> using namespace std; class container { float a,b; public: void get() { cout<<endl<<"Enter value for A="; cin>>a; cout<<endl<<"Enter value for B="; cin>>b; } void disp() { cout<<endl<<a; cout<<endl<<b; } friend container addition(container,container); }; container addition(container X,container y) { container Z; Z.a=X.a+y.a; Z.b=X.b+y.b; return Z; } int main() { container P,Q,R; P.get(); P.disp(); Q.get(); Q.disp(); R=addition(P,Q); R.disp(); return 0; } Output - Enter value for A=12 Enter value for B=12 12 12 Enter value for A=1 Enter value for B=1 1 1 13 13 2.  If class one is friend function of two it not means that two is friend functio...

Cpp programming tutorial 1

C++ language - This is a very similar to c language and it have all the concept of c language and their is more in c plus plus it have many new concept like classes and object was introduced here constructor , destructor many more concept was in c plus plus and because c plus plus have more enhancement and more simple to use it also object oriented programming .  OOPs concept with example - The meaning of object oriented programming(oops) is it works on concept of classes and object or in other word oops concept is based on class and object . class is a body to create object in object oriented it treat data as a critical element and decompose the problem in object and build data function according to the object and in object oriented programming we can use it for protecting data and for privacy of data so not all variable can access it . BENEFIT OF OBJECT ORIENTED PROGRAMMING - 1. Because of hiding data method we secure our data and system for accessing all variable . 2. It have...
