Chapter 12, Problem 15SA
Explanation of Solution
The problem with the program has been explained in the in-lined comments:
#include <iostream>
using namespace std;
int main()
{
//pointer variables declared and memory allocated
double *firstPtr = new double; //Line 1
double *nextPtr = new double; //Line 2
//value assigned to pointer variable
*firstPtr = 62; //Line 3
//nextPtr is assigned the pointer firstPtr
//so nextPtr points to a memory location
//having a stored value of 62
nextPtr = firstPtr; //Line 4
//memory pointed to by both the pointers are
//deallocated
delete firstPtr; //Line 5
delete nextPtr; //Line 6
//fresh memory i...

A robot is initially located at position (0; 0) in a grid [?5; 5] [?5; 5]. The robot can move randomly in any of the directions: up, down, left, right. The robot can only move one step at a time. For each move, print the direction of the move and the current position of the robot. If the robot makes a circle, which means it moves back to the original place, print "Back to the origin!" to the console and stop the program. If it reaches the boundary of the grid, print \Hit the boundary!" to the console and stop the program.
A successful run of your code may look like:Down (0,-1)Down (0,-2)Up (0,-1)Left (-1,-1)Left (-2,-1)Up (-2,0)Left (-3,0)Left (-4,0)Left (-5,0)Hit the boundary!
or
Left (-1,0)Down (-1,-1)Right (0,-1)Up (0,0)Back to the origin!
About: This program is to give you practice using the control ow, the random number generator, and output formatting. You may use <iomanip> to format your output. You may NOT use #include "stdafx.h".

This function should compute and return the list of all numbers that the positive integer n can be converted to by treating it as a string and replacing some substring m of its digits with the new substring of either 2*m or m/2, the latter substitution allowed only when m is even so that dividing it by two produces an integer. This function should return the list of numbers that can be produced from n in a single step. To keep the results more manageable, we also impose an additional constraint that the number of digits in the chosen substring m must be between mink and maxk, inclusive. The returned list must contain the numbers in ascending sorted order.arrow_forward
- C++ only. Do not copy. Correct code will upvoted else downvote. Monocarp is playing a PC game. Presently he needs to finish the principal level of this game. A level is a rectangular framework of 2 lines and n sections. Monocarp controls a character, what begins in cell (1,1) — at the convergence of the 1-st line and the 1-st segment. Monocarp's character can move starting with one cell then onto the next in one stage if the cells are nearby by side or potentially corner. Officially, it is feasible to move from cell (x1,y1) to cell (x2,y2) in one stage if |x1−x2|≤1 and |y1−y2|≤1. Clearly, it is denied to go external the matrix. There are traps in certain cells. In case Monocarp's character winds up in such a cell, he bites the dust, and the game closures. To finish a level, Monocarp's character should arrive at cell (2,n) — at the crossing point of line 2 and section n. Assist Monocarp with deciding whether it is feasible to finish the level.

This function takes what kind of animal or animals you have and returns a shopping list for your pet or pets. PLAN FOR THIS FUNCTION: determine the word for a single kind of the animal. if the input is "mice", then we want the output to contain "mouse" (don't worry about any other unusual plurals). Otherwise, look for words that end with "es" and remove the final "es", so "foxes" goes to "fox". Otherwise, remove a final "s". Otherwise, assume that the word is singular. build and return a shopping list, which will be a list of strings. shopping lists should be in the shape: ["mouse food", "mouse treats", "mouse bed", "mouse house"] Sample calls should look like: >>> pet_shopping list("mice") I'mouse food', 'mouse treats',…arrow_forwardCommon Time Zones Function Name: commonTimeZones() Parameters: code1( str ), code2( str) Returns: list of common time zones ( list ) Description: You and your friend live in different countries, but you figure there's a chance that both of you might be in the same time zone.
