Answer:
3) A Single linked list is a sequence of elements in which every element has link to its next element in the sequence.
DATA LINK
DATA stores actual value , LINK stores address of next node
As per information given in question, letters at the even addresses are items in linked list and the odd addresses will be used as links.
Even Address Odd Address
12 (Stores 't') 13 (Used as link)
14 (Stores 'm') 15 (Used as link)
16 (Stores 'a') 17 (Used as link)
18 (Stores 'r') 19 (Used as link)
20 (Stores 's') 21 (Used as link)
Numbers represented by circle are addresses of respective nodes. Here Front or Head has address 16. Which represents the Head Node.
Following image represents the word "smart" with respective nodes and their addressing.
Numbers represented by circle are addresses of respective nodes.
The head pointer is: 20

Explanation:
The testing tool is capable of uncovering a number of vulnerabilities, to scan small web applications, to uncover over 25 types of web application vulnerabilities, to detect TLS/SSL vulnerabilities and misconfigurations, to measure the source code quality of a web application, to detect and utilize SQL injection vulnerability in a website’s database, to find over 200 types of security issues in web applications, to check web applications for security vulnerabilities.
The security testing tool supports command-line access for advanced users can also be used to intercept a proxy for manually testing a webpage.
Answer:
#include<iostream>
using namespace std;
//main function
int main(){
//initialize the variables
int n = 5;
int j=1;
// for loop
for(;j<=n;j++){
cout<<"*"; //print the '*'
}
}
Explanation:
Create the main function and declare the variable n with the value 5 and initialize the variable j with zero.
take a for loop for executing the statement again and again until a condition is not false.
Syntax for loop:
for(initialize; condition; increment/decrement)
{
statement;
}
we can initialize the variable outside as well but the semicolon always present in the loop otherwise compiler gives the error.
for example:
int i=0;
for(; i<4; i++){
statement;
}
The condition put in the original code is j <= n and n has the value 5. so, the loop executes 5 times and inside the loop, write the print statement for print the character '*'.
