Answer:
B) Punctuation
Explanation:
Punctuation are greatly used in different programming languages for different purposes. In the Java, C++ and C# Programming languages for example, two popular punctuation marks are the comma (,) and semi-colon (;). The comma is used for separating elements of a list and arrays, while the semi-colon indicates end of an executable statement or line of code. Other popular punctuation marks used in programming are periods (dot), question marks, parenthesis angle brackets and braces each implementing a specific grammatical syntax in the language.
Answer:
class Main {
public static void printPattern( int count, int... arr) {
for (int i : arr) {
for(int j=0; j<count; j++)
System.out.printf("%d ", i);
System.out.println();
}
System.out.println("------------------");
}
public static void main(String args[]) {
printPattern(4, 1,2,4);
printPattern(4, 2,3,4);
printPattern(5, 5,4,3);
}
}

Above is a compact implementation.
Answer:
Close or disable all unused running apps.
Explanation:
Closing programs running in the background on your computer or mobile device helps to free up system resources for your other programs. These problems can be resolved where your system is running slowly or two programs are trying to use the same device hence causing the device or system to drag.
Answer:
C). STEM students are encouraged to blend and expand their knowledge of all four subject areas.
Explanation:
STEM education is characterized as a learning and development approach that focuses upon an amalgamation of four subject areas including science(S), technology(T), engineering(E), and Mathematics(M). Thus, each letter stands for a subject domain and this integration of four subjects primarily aims to 'blend and expand the knowledge of the students in these areas' integratively. It helps in developing and sustaining the interests of young learners through this integrated approach which also assists them with unique opportunities. Thus, <u>option C</u> is the correct answer.
Answer:
import java.util.Scanner;
public class ss11{
public static void main (String[]args) {
Scanner keyboard = new Scanner (System.in)
String a1, a2, a3, a4, a5;
int i1, i2, i3, i4, i5;
System.out.println("Enter a four bit binary number:");
a1= keyboard.next();
a2= a1.substring(0,1);
a3= a1.substring(1,2);
a4= a1.substring(2,3);
a5= a1.substring(3,4);
i1 = Integer.parseInt(a2);
i2 = Integer.parseInt(a3);
i3 = Integer.parseInt(a4);
i4 = Integer.parseInt(a5);
i1= i1 * 8;
i2= i1 * 4;
i3= i1 * 2;
i4= i1 * 1;
i5= i1+i2+i3+i4;
System.out.println("The converted decimal number is: +i5);
}
}
