Shared pointers: A “shared_ptr” is a smart pointer which maintains shared ownership of an object using pointer. Shared pointers are used in managing the ownership of the dynamically allocated object. Shared pointers are used by more than one owner available for the objects that are allocated dynamically. Example: The following code illustrates the use and creation of shared pointer: //creating a shared pointer of integer data type shared_ptr<int> sDPtr1 (new int); //creating an array of shared pointer shared_ptr<int[]> sDPtr2 (new int[5]); Explanation: In the above code snippet, a smart pointer of integer data type is assigned directly.

Chapter 10, Problem 32RQE

Program Plan Intro

Shared pointers:

A “shared_ptr” is a smart pointer which maintains shared ownership of an object using pointer.

Shared pointers are used in managing the ownership of the dynamically allocated object.

Shared pointers are used by more than one owner available for the objects that are allocated dynamically.

Example:

The following code illustrates the use and creation of shared pointer:

//creating a shared pointer of integer data type

shared_ptr<int> sDPtr1 (new int);

//creating an array of shared pointer

shared_ptr<int[]> sDPtr2 (new int[5]);

Explanation:

In the above code snippet, a smart pointer of integer data type is assigned directly.

C++ Programming Problem: Newton is a brilliant mathematician and solving triangles problems fascinates him. Today he is given a sequence of positive integers V1, V2, ., VN. You must choose three elements Vx, Vy, Vz (x, y, z is vertices) such that the triangle formed have these properties: |XY|= Vz, |XZ|=Vy, |YZ|=Vx and the angle |ZYXZ|= 0 satisfies cose2P/Q, where 0 should be maximum possible. Find any such triangle or determine that it does not exist. Develop a C++ code which prints the value of x, y, z in a single line and print "Invalid" if not possible. Test Case: 412 9765 Result: 324

#include<iostream>using namespace std;void main(){double pi = 0, denominator = 1;int counter = 999999;for (int x = 0; x < counter; x++){if (x % 2 != 0){pi = pi - (1 / denominator);}else{pi = pi + (1 / denominator);}denominator = denominator + 2;}pi = pi * 4;cout << " So the computed value of a PI is = " << pi << endl;cout << " ";//return 0;system("pause");} Note: This a program called ComputePI to compute the value of π Tutor just have to Modify This program to use nested-if (if ... else if ... else if ... else) instead.

c++ coding language I need help with part B and C please. If you are unable to do both, then PLEASE prioritize part C. I am really stuck and really can use the help. This is the code for c that was provided in order to guide me: const int N =31; // N parking spaces bool parking[N]; // the garage void EmptyTheLot(bool parking[], int N) { for(int i=0; i<N; i++) p[i]=false; // empty space } // returns -1 if no space found, //otherwise it returns 0<=i<N for a valid space. int FindSpace(int PlateNumber, bool parking[], int N) { // ????? } main() { EmptyTheLot(parking, N); // start with an empty parking garage. // get plate numbers and fill lot. }
