Solution:
It is important because, it has to do operation on so without, data structures and algorithms.
It performs these operation:
1)Take an input
2) Process it
3) Give back the output.
The input can be in any form, for ex while searching for directions on google maps, the starting point and the destination as input to google maps, while logging in to any social sites, We have to give our email and password as input and so on.
Similarly, in the third step, the computer application gives us output in some form or the other.
To make this process efficient, we need to optimize all the three steps.
Answer:
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter the number of bottles and cans:");
int numberOfbottles = in.nextInt();
int numberOfcans = in.nextInt();
System.out.printf("Bottles: %8d\n", numberOfbottles);
System.out.printf("Cans: %8d\n", numberOfcans);
}
}
Explanation:
Ask user to input the number of bottles and cans using Scanner class
Print the results so that the numbers to the right line up (Since we know that the numbers have at most 8 digits, we can use %8d in printf. Also, be aware that how printf statements are written so that the numbers line up)
Answer:
The code will get stuck in an infinite loop.
Explanation:
Since val is decreasing by 1 each time it meets the criteria of being smaller than 10, your code will get stuck in an infinite loop since val will always be smaller than 10.
Hope this helps :)
Answer:
DECLARE SUB SQUARE (N)
CLS
INPUT “ENTER ANY NUMBER”; N
CALL SQUARE(N)
END
SUB SQUARE (N)
S = N ^ 2
PRINT “SQUARE OF NUMBER “; S
END SUB
