Answer:
B. GRID COMPUTING , ON - DEMAND COMPUTING AND REAL TIME COMPUTING
Explanation:
Grid computing, on-demand computing and real time computing are currently the most impactful information technology processes. The Grid computing from example entails distributed computing whereby computing resources are distributed across different systems for a computing task. This is seen in server systems where a super virtual computer composed of a network of computers are connected to share resources and perform large tasks. This form of computing has majorly affected and improved complex computing tasks today.
On demand and real time computing are also other notable trends in IT with real time computing bringing the power of live and direct coverage of information to our screens and on demand making it possible for the average user to access computing resources as needed such as in the services of cloud computing providers

Answer:
- var today = new Date();
- var dateComp = [];
- dateComp[0] = today.getDate();
- dateComp[1] = today.getMonth();
- dateComp[2] = today.getFullYear();
-
- switch(dateComp[1]){
- case 0:
- console.log("Jan " + dateComp[0] + "," + dateComp[2])
- break;
- case 1:
- console.log("Feb " + dateComp[0] + "," + dateComp[2])
- break;
- case 2:
- console.log("Mar " + dateComp[0] + "," + dateComp[2])
- break;
- case 3:
- console.log("Apr " + dateComp[0] + "," + dateComp[2])
- break;
- case 4:
- console.log("May " + dateComp[0] + "," + dateComp[2])
- break;
- case 5:
- console.log("Jun " + dateComp[0] + "," + dateComp[2])
- break;
- case 6:
- console.log("Jul " + dateComp[0] + "," + dateComp[2])
- break;
- case 7:
- console.log("Aug " + dateComp[0] + "," + dateComp[2])
- break;
- case 8:
- console.log("Sept " + dateComp[0] + "," + dateComp[2])
- break;
- case 9:
- console.log("Oct " + dateComp[0] + "," + dateComp[2])
- break;
- case 10:
- console.log("Nov " + dateComp[0] + "," + dateComp[2])
- break;
- case 11:
- console.log("Dec " + dateComp[0] + "," + dateComp[2])
- break;
- }
Explanation:
The solution code is written in JavaScript.
Firstly, create a Date object (Line 1). The date object will automatically capture the current date and time.
Next create an array dateComp to hold the day, month and year (Line 3 -5). We use the getDate method to get current day, getMonth method for current month and getFullYear method for current year.
This is important to note that the getMonth method will return the value range from 0 - 11 with the Jan is represented as 0, Feb is 1 and so forth. Presume we intend to display the date using the format "month day, year", we can create a switch structure to check the month value which is range from 0 to 11. If month value is 0, generate string Jan + current day + "," + current year. We generate the date string based on different switch cases (7 - 44). We shall see the output similar to the date string as shown below:

Answer:
The output is "A"
Explanation:
public class Solution {
public static void main(String args[]) {
mystery(7);
}
public static void mystery(int a) { System.out.println("A"); }
public static void mystery(double a) { System.out.println("B"); }
public static void mystery(int a, double b) { System.out.println("C"); }
public static void mystery(double a, int b) { System.out.println("D"); }
}
In the code above; mystery is defined in four different ways called method overloading. Method overloading is when same method is defined with different parameters.
In the first case; mystery will be called if the argument is int.
In the second case; mystery will be called if the argument is double.
In the third case; mystery will be called if the arguments are int and double.
In the fourth case; mystery will be called if the arguments are double and int.
When mystery(7) is called; the mystery method requiring only int will be called and the output is "A".
