Answer:
Transistors transformed the world of electronics and had a huge impact on computer design. Transistors made of semiconductors replaced tubes in the construction of computers. By replacing bulky and unreliable vacuum tubes with transistors, computers could now perform the same functions, using less power and space.
Answer:
public class Pyramid {
public static void main(String[] args) {
int h = 7;
System.out.println("Pattern A");
for(int i = 1; i <= h; ++i)
{
for(int j = 1; j <= i; ++j) {
System.out.print("+");
}
System.out.println();
}
System.out.println();
System.out.println("Pattern B");
for (int i = 1; i<=h; ++i)
{
for(int j = h; j >=i; --j){
System.out.print("+");
}
System.out.println();
}
}
}
Explanation:
- The trick in this code is using a nested for loop
- The outer for loop runs from i = 0 to the heigth of the triangle (in this case 7)
- The inner for loop which prints the (+) sign runs from j = 0 to j<=i
- It prints the + using the print() function and not println()
- In the pattern B the loop is reversed to start from i = height
import java.util.Scanner;
public class JavaApplication58 {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Enter a positive integer:");
String num = scan.nextLine();
for (int i = num.length()-1; i >=0; i--){
System.out.println(num.charAt(i));
}
}
}
