Answer:
The challenge of cost control
The challenge of competence
The challenge of reduced system delivery times.
Explanation:The Challenge of Cost control is a major challenge affecting the software engineering in the 21st century,the cost of Microchips and other hardware are constantly rising.
The challenge of competence is another major challenge affecting software engineering in the 21st century,as most software engineers lack the required competence to handle some of the issues facing softwares.
The challenge of reduced system delivery times is a major challenge likely to affect software engineering in the 21st century,as people required the software to be available in the shortest possible time.
<u>Output:</u>
f1 in A
f2 in A
f1 in B
f2 in A
f1 in A
f2 in A
f1 in B
f2 in B
<u>Explanation:</u>
In this snippet, the code makes use of virtual functions. A virtual function is defined as a function that is defined in the base class and redefined in the derived class. If the derived function accesses the virtual function, the program will get executed with the derived class’s version of the function.
In this code, we define the virtual function f1() in class A and also redefine it in class B which is the derived class of A. While executing the program, the function g which takes the object b (class B’s object) as a parameter. It will print class B’s version of f1() rather than class A’s version. This is working off the virtual function.
Answer:
It will be a java code.
Explanation:
import java.util.Scanner;
public class StringInputStream {
public static void main (String [] args) {
Scanner inSS = null;
String userInput = "Jan 12 1992";
inSS = new Scanner(userInput);`
String userMonth = "";
int userDate = 0;
int userYear = 0;
/* Your solution goes here */
System.out.println("Month: " + userMonth);
System.out.println("Date: " + userDate);
System.out.println("Year: " + userYear);
return;
}
}

Answer:
method for user authentication to the network
Provide detailed information about a user
Explanation:
An in AD, a user account consists of all the information that includes user names, passwords, and groups. All these information defines a domain user in which a user account has membership access to. With the advanced features of Kerbos, mutual authentication in user accounts to a service is achieved.
