Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Quit", "quit", or "q" for the line of text.
Ex: If the input is: (see image attached)
my code is this one but i dont know what im doing wrong:
#include
using namespace std;
int main()
{
while (true)
{
string word;
if (word.compare("Quit")==0)
{
break;
}
else if (word.compare("quit")==0)
{
break;
}
int len=word.length();
cout = 0; i--)
{
cout << word[i];
break;
}
cout << endl << endl;
}
cout << "Thank You..!";

This program outputs a downwards facing arrow composed of a rectangle and a right triangle. The arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width. #include int main(void) {int arrowBaseHeight = 0;int arrowBaseWidth = 0;int arrowHeadWidth = 0;printf("Enter arrow base height:\n");scanf("%d", &arrowBaseHeight);printf("Enter arrow base width:\n");scanf("%d", &arrowBaseWidth);printf("Enter arrow head width:\n");scanf("%d", &arrowHeadWidth);printf("\n");// Draw arrow base (height = 3, width = 2)printf( "**\n");printf( "**\n");printf( "**\n");// Draw arrow head (width = 4)printf( "****\n");printf( "***\n");printf( "**\n");printf( "*\n");return 0;}a. Modify the given program to use a loop to output an arrow base of height arrow_base_height. b. Modify the given program to use a loop to output an arrow base of width arrow_base_width.c. Modify the given program to use a loop to output an arrow head of width arrow_head_width.
Answers
Answer:
Here is the C program:
#include <stdio.h> //to use input output functions
int main(void) { //start of main function
int arrowBaseHeight = 0; //stores value for arrow base height
int arrowBaseWidth = 0; //stores value for arrow base width
int arrowHeadWidth = 0 ; //stores value for arrow head width
int i, j; //to traverse through the rows and columns
printf("Enter arrow base height:\n"); //prompts user to enter arrow base height value
scanf("%d", &arrowBaseHeight); //reads input value of arrow base height
printf("Enter arrow base width:\n"); //prompts user to enter arrow base width value
scanf("%d", &arrowBaseWidth); //reads input value of arrow base width
while (arrowHeadWidth <= arrowBaseWidth) { //iterates as long as the value of arrowHeadWidth is less than or equals to the value of arrowBaseWidth
printf("Enter arrow head width:\n"); //prompts user to enter arrow head width value
scanf("%d", &arrowHeadWidth); //reads input value of arrow head width
printf("\n"); }
for (i = 0; i < arrowBaseHeight; i++) { //iterates through rows
for (j = 0; j < arrowBaseWidth; j++) { //iterates through columns
printf("*"); } //prints asterisks
printf("\n"); } //prints a new line
for (i = arrowHeadWidth; i > 0; i--) { //loop for input length
for (j = i; j > 0; j--) { //iterates for triangle ( to make arrow head)
printf("*"); } //prints asterisks
printf("\n"); } } //prints new line
Explanation:
The program asks to enter the height of the arrow base, width of the arrow base and the width of arrow head. When asking to enter the width of the arrow head, a condition is checked that the arrow head width arrowHeadWidth should be less than or equal to width of arrow base arrowBaseWidth. The while loop keeps iterating until the user enters the arrow head width larger than the value of arrow base width.
The loop is used to output an arrow base of height arrowBaseHeight.
The nested loop is being used which as a whole outputs an arrow base of width arrowBaseWidth. The inner loop draws the stars and forms the base width of the arrow, and the outer loop iterates a number of times equal to the height of the arrow.
The last nested loop is used to output an arrow head of width arrowHeadWidth. The inner loop forms the arrow head and prints the stars needed to form an arrow head.

Answer:
Here is the corrected code:
import java.util.*;
public class DebugNine36 { //class name
public static void main(String[] args) { //start of main method
ArrayList<String>products = new ArrayList<String>(); //creates an ArrayList of type String names products

System.out.println(products.get(x)); } } //displays each item/element in products array list
Explanation:
In the code the following statement are corrected:
1.
ArrayListproducts = new ArrayList();
This gave an error: cannot find symbol
This is corrected to :
ArrayList<String>products = new ArrayList<String>();
2.
products.add(shampoo);
products.add(moisturizer);
products.add(conditioner);
Here shampoo moisturizer and conditioner are String type items that are to be added to the products so these strings have to be enclosed in quotation marks.
This is corrected to :
products.add("shampoo");
products.add("moisturizer");
products.add("conditioner");
3.
display();
This method is called without giving any arguments to this method. The method display takes an ArrayList as argument so it should be passed the arraylist products to avoid error that actual and formal argument lists differ in length .
This is corrected to :
display(products);

The trigonometry book says: sin^2(t) + cos^2(t) = 1 Write a Python program that verifies the formula with the help of the Python Math module. Note that the trigonometric functions in the module act on the angles in radians. Your program should perform the following steps 3 times: 1. Pick a random number between 0 and 180 degrees representing an angle in degrees, say Dangle 2. Convert the angle from degrees to radians, say Rangle 3. Use the Math module to find and print the values of sin(Rangle) and cos(Rangle), and 4. Compute and print the value of the above expression: sin^2(Rangle) + cos^2(Rangle). You can then visually verify if the result printed is 1 (or close to it).
Answers
Answer:
If you open your python-3 console and execute the following .py code you will have the following output. (Inputing 20 e.g)

cosene( 0.3490658503988659 ) = 0.9396926207859084
sine( 0.3490658503988659 ) = 0.3420201433256687
sin^2( 0.3490658503988659 ) + cos^2( 0.3490658503988659 ) = 1.0

The algorithm S(A, n, i) selects all the j-th smallest elements (with j ≤ i) from an array A of n elements, by using linearselect to select each of the j-th smallest elements (with j ≤ i). Clearly, one could also implement S alternatively as T(A, n, i), which first sort A (on average-case and on worstcase, the sorting takes time O(n log n) using mergesort) and then select the first i elements. Please compare the average-case complexities of the two algorithms; i.e., For the average-case complexities, under what conditions (on the choices for i), S is better than T or vice versa
Answers
Answer:
Follows are the solution to this question:
Explanation:
In the linear selected algorithms scans the given field sequentially but instead calculates the fixed amount by crossing the items throughout the list since they are displayed. Take into consideration the various chosen algorithm:
S(A, n, i) Algorithm:
In array B, copy array A items.
To save results, construct an array C of height.
Start Loop j = 0 to i-1.
Determine array B's lowest value.
In array C, also save the minimum value.
Delete from array B the minimum value.
Back the C array.
Analysis of runtime:
In i iterations, the external loop is used, although i have to compute the number of small lots.
This internal loop should run and calculate the minimum variable, whereby n is the input array length at the most values of n.
Its cumulative runtime is equal to O(in)+C =
O(in). All remaining operations are done at a precise rate.
The combine type technique requires that division concept to
sort the sorted array either in or upwards backward order.
Follow the appropriate method using merge type to
select the shortest items of a certain list.
T (A, n, i) algorithm:
In B array, copy array A elements.
To save the output, build a C array of sizes.
Using merge form in an increasing order to sort all items of the B list.
Start the loop j= 0 to i-1.
Save A[j] value in C[j].
Return array C,
return array C.
Analysis of run time:
The combined function requires O (n log n) to arrange a size n list.
Its number of samples in the process to construct the resulting sequence becomes equal to i since i is the minimum number of elements to also be calculated. All remaining transaction is performed in continuous time.
The time to work is O (n log n) + O i + C = O (n log n). The time needed.
The complexities of the following algorithms are similar:
Scenario 1: S is stronger than to the T-algorithm
Consider the number for smallest elements to also be calculated or even the I value is significantly smaller than the number of array elements. Let i = 2 and n = 16.
Its algorithm S requires O(in) time for both the calculation of a result, who in this case is equivalent to (2 16).
If algorithm T finds the initiative of O (n log n), who in this case is equivalent to (16 logs 16) = (16 4).
The S method, therefore, operates better than that of the T algorithm, if another I value exceeds the log n value.
Scenario 2: Algorithm T is much more successful that algorithm S
Evaluate if the number of components which must be calculated is smaller or if the value of I is comparable with that of the items inside the array.
Let the I = 12 quality and n = 16 value. Its S method applies O(in) time, and in this, the situation is just like (12 16).
Hence, the algorithm T performs better than the algorithm S when the value of i is greater than the value of the log n.
