Answer:
Instance variables can be declared anywhere inside a class.
Although there isn't any rule to declare instance variables before methods, and they can be declared anywhere in the class, they cannot be declared inside method definitions of class.
///////////////////////////////////////////////////////////////////////////////////////////////////////////
<em>By convention class names begin with an uppercase letter, and method and variable names begin with a lowercase letter.</em> - True.
<em>Instance variables exist before methods are called on an object, while the methods are executing and after the methods complete execution.</em> - True.
<em>A class normally contains one or more methods that manipulate the instance variables that belong to particular objects of the class.</em> - True
Answer:

- The above question asked about that technology which is used to connect the people to communicate and the technology is social media which gives the features to connect and communicate all over the world with the help of the internet. Hence "Social media" is the correct answer.
{{5,10,15,20},{25,30,35,40}} is answer where zero is not found.
<u>Explanation:</u>
This program finds zero in giving as arrays of value as a parameter. The program has two loop. One is a row of the array and the other is column loop for each row o an array. For loop is created with a variable namer row and the loop ends with a length of the array of each row.
In side row for loop col loop is created and loop ends with each row-column length of cells. If data in each cell i.e (row, col) calue is zero it returns true and the loop is terminated immediately.
In case if the value of the cell doesn’t found zero it never terminates the loop and continuous loop and returns a false value. Find Zero functions accept the two-dimensional array and check whether cell value is zero. If it is zero found return true otherwise it returns false.
Answer:
C. 220.100.100.45 to 220.100.100.46
Explanation:
The Classless IP subnetting of 220.100.100.0 begins from the fourth octet of the IP address. To get 45 subnet mask, it uses 6 bits from the fourth octet, which approximately give 64 subnets, while the remaining 2 bits are used for host IP addressing.
The useable host IP addresses are gotten from the formula '
-2', with n=2 bits.
useable host IP addresses = 2^2 - 2 = 2 addresses per subnet.
While the 12th subnet is 12 x 2^2 = 44.
This means that the 12th subnet mask starts with 220.100.100.44 (as the network address) and ends with 220.100.100.47 as broadcast IP address, while '.45' and '.46' are the assignable addresses of the subnet.
