Answer: Stealth scanning technique
Explanation:
Stealth Scanning technique includes the following steps:
1. The client upon sending a single SYN packet to is responded by SYN/ACK packet if the port is open.
2. The port is assumed to be in closed state if the RST packe t is sent from the server.
3. This RST packet is sent by the client to close the initiation process so that a connection cannot be established.
Classes cannot Initialize data members in the class definition.
B) Initialize data members in the class definition
<u>Explanation:</u>
Class is defined by end user data type where it can handle multiple data type and referred to other classes also. Class is also called as data structure object or object class.
Due to class methods total programming language coding style is changes. For example employee of an organization should hold his or her employee number, address detail, spouse details, salary details
Where in old style programming language we need to declare separate variable to hold the data types, where we can define employee as class which can hold employee number, address fields, and again define salary details as other class and add employee->employee number where key connect between to class which is called derived class.
Answer:
Following are the code block in the Java Programming Language.
//define recursive function
public static long exponentiation(long x, int n) {
//check the integer variable is equal to the 0.
if (x == 0) {
//then, return 1
return 1;
}
//Otherwise, set else
else {
//set long data type variable
long q = exponentiation(x, n/2);
q *= q;
//check if the remainder is 1
if (n % 2 == 1) {
q *= x;
}
//return the variable
return q;
}
}
Explanation:
<u>Following are the description of the code block</u>.
- Firstly, we define the long data type recursive function.
- Then, set the if conditional statement and return the value 1.
- Otherwise, set the long data type variable 'q' that sore the output of the recursive function.
- Set the if conditional statement and check that the remainder is 1 and return the variable 'q'.
Answer:
True.
The code skips the else command
Explanation:
I will answer this question with the following code segment
<em>n = 1</em>
<em>If n > 0:</em>
<em> Print("greater than 0")</em>
<em>else:</em>
<em> Print("not greater than 0")</em>
<em />
From the code segment above
<em>Print("greater than 0")</em> will be executed because the condition <em>If n > 0 </em>is true
Since the if condition is true, the else condition will not be executed
