Control structures

Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.

Switch Statement

The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

Question

What is the output when we run the following code:
def countdown(n):
if n <= 0:
print('Goooo!')
else:
print(n)
countdown(n-1)
countdown(3)
3
2
1
Goooo!

Accumulating Totals in a Loop Summary In this lab, you add a loop and the statements that make up the loop body to a Java program that is provided. When completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. Your loop should execute until the user enters the character X instead of L for left-handed or R for right-handed. The inputs for this program are as follows: R, R, R, L, L, L, R, L, R, R, L, X Variables have been declared for you, and the input and output statements have been written. Instructions Ensure the file named LeftOrRight.java is open. Write a loop and a loop body that allows you to calculate a total of left-handed and right-handed people in your class. Execute the program by clicking Run and using the data listed above and verify that the output is correct.
Correct code to output the following: 0 2 4 6 8 10 12 14 16 18 CODE: int[] numbers = new int[10]; for(int i=0; i < numbers.length; ++i) numbers[i] = i * 2; for(int i=0; i < numbers.length; i++) System.out.print(numbers[++i] + " "); System.out.println();
please code in python You place a pawn at the top left corner of an n-by-n chess board, labeled (0,0). For each move, you have a choice: move the pawn down a single space, or move the pawn down one space and right one space. That is, if the pawn is at position (i,j), you can move the pawn to (i+1,j) or (i+1, j+1). Ask the user for the size of a chessboard, n (integer). Find the number of different paths starting from (0,0) that the pawn could take to reach each position on the chess board. For example, there are two different paths the pawn can take to reach (2,1). Look at the diagrams below to convince yourself of this. You can see the four paths that you can take by move 2. Start -> Move 1 -> Move 2 (0,0) -> (1,0) -> (2,1) (0,0) -> (1,0) -> (2,0) (0,0) -> (1,1) -> (2,1) (0,0) -> (1,1) -> (2,2) Print the board with the number of ways to reach each square labeled as shown below. For example: Enter a board size: 4 1 0 0 0 1 1 0 0 1 2 1 0 1 3 3 1
solve in java Integer numInput is read from input representing the number of integer values to be read next. Use a loop to read the remaining integer values from input. For each integer value read, output "Value read: " followed by the value. Then, output "Highest: " followed by the highest of the integer values read. End each output with a newline. Ex: If the input is: 3 220 -490 5 then the output is: Value read: 220 Value read: -490 Value read: 5 Highest: 220 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 import java.util.Scanner; public class HighestValues { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumInput; intinputValue; inthighestVal=0; inti; numInput=scnr.nextInt(); /* Your code goes here */ } }

Using Java, This program should print out first N powers of 2 starting from 2^1, until 2^N. The program first asks the user to enter the max power of 2, reads it using nextInt() and then uses the while loop to print out first n powers of 2. e.g. Enter the number of powers of two: 10 2^1 = 2 2^2 = 4 2^3 = 8 2^4 = 16 2^5 = 32 2^6 = 64 2^7 = 128 2^8 = 256 2^9 = 512 2^10 = 1024
Output integer's digits Given an input positive integer, output each digit on its own line, starting with the rightmost digit. Ex: If the input is 935, the output is: 5 3 9 Hints: Use the mod operator (%) to get the rightmost digit. Mod by 10 to get the rightmost digit. Use a loop that keeps a current dividend (the number being divided). In each iteration, output the rightmost digit, then update the divisor by dividing by 10. End the loop when the divisor is 0. in java

You have been hired by a local organic sod company to write coverage calculator for their website. Organic sod is cut into rectangles 9 square foot in area for lawn installation. Your program will prompt the customer for the length and the width of a rectangular area being covered with sod. Implement the following "pseudocode" to obtain the number of pieces to order. • Compute the area of the rectangle to be covered • Divide the area by 9 • Convert the result to an integer and then add 1 Below is a sample run with Python output in blue and user input in black. Enter length:200 Enter width:40 You should order 889 pieces.
