C++ Two stacks of the same type are the same if they have the same number of elements and their elements at the corresponding positions are the same. Overload the relational operator == for the class linkedStackType that returns true if two stacks of the same type are the same; it returns false otherwise. Also, write the definition of the function template to overload this operator. Write a program to test the various functions and operators of the class linkedStackType.
C++ Code, Function below is a member function of Sequence class: template <class T> T& Sequence <T> ::entry(int pos) { if (pos < 0 || pos >= size) { cout << "Invalid, please check!\n"; T x; return x; } NodeRecord* current = head; for (int a = 0; a < pos; a++) { current = current->next; } return current->value; }// END entry For the function above, a. Draw the code diagrams with labels for statements and branches. b. Provide test cases for statement, branch, and path coverages (properly identifying all the test cases with correct labels and the respective function).
Create a C++ Function Template named swap so that it has two parameters of the same type. A Template Function created from swap will exchange the values of these two parameters. Create a C++ Function Template named multiples so that it has three parameters sum, x, and n. The first two parameters will have the type represented by the function template type parameter WhatKind. n will always be int. The return type is void. All parameters are passed by value except for sum which is passed by reference. A Template Function created from multiples will compute... sum = 1 + x + 2x + 3x + ... + nx Create a C++ Class called Mathy that also contains these two functions and that is properly templatized. Write code in your main function to demonstrate that each function works well individually and when used from within the class using multiple types. Demonstrate that you achieve the same results using both the templatized class and functions.
IN C++ To gain a better understanding of polymorphic and virtual functions start with the following simple example. Notice we have not defined a virtual function yet. // Part1.h. Note, this header file will have TWO classes declared.#include <iostream>using namespace std;class Base{public:void testFunction ();};class Derived : public Base{public:void testFunction ();};// Part1.cpp. Note this implementation file will have TWO class defined.#include "Part1.h"void Base::testFunction (){cout << "Base class" << endl;}void Derived::testFunction (){cout << "Derived class" << endl;}// main.cpp #include "Part1.h"int main(){Base* ptr = new Base;ptr -> testFunction (); // prints "Base class"delete ptr;ptr = new Derived;ptr -> testFunction (); // prints "Base class" because the base class // function is not virtualdelete ptr;return 0;} Now modify the code with the following (all other code should remain the same). class Base{public:virtual void testFunction…

Using C++ Without Using linked lists: Create a class AccessPoint with the following: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overLap that checks if two access points overlap their coverage and returns true if they do. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location. Represent this with bars like, IIIII. Each bar can represent 20% Test your class by writing a main function that…
in c++ Write a function named “contains” that accepts a vector of Variableobject pointers and a search string. It will return the list of Variableobject pointers that contains that search string.Please note that the list can contain pointers to both Variable or VariableString objectsor any of its derived class objects. Build a list of pointers pointing to mixed objects of Variable and VariableString objectsand show your function returns the mix of both.
Implement in C Programming 6.10.1: Function pass by pointer: Transforming coordinates. Define a function CoordTransform() that transforms its first two input parameters xVal and yVal into two output parameters xValNew and yValNew. The function returns void. The transformation is new = (old + 1) * 2. Ex: If xVal = 3 and yVal = 4, then xValNew is 8 and yValNew is 10. #include <stdio.h> /* Your solution goes here */ int main(void) { int xValNew; int yValNew; int xValUser; int yValUser; scanf("%d", &xValUser); scanf("%d", &yValUser); CoordTransform(xValUser, yValUser, &xValNew, &yValNew); printf("(%d, %d) becomes (%d, %d)\n", xValUser, yValUser, xValNew, yValNew); return 0;}
C++ (Last time the solution was unclear with errors) Write a class template that uses a vector to implement a stack data structure with these member functions: 1. (constructor) : Construct stack (public member function ) 2. empty : Test whether container is empty (public member function ) 3. size : Return size (public member function ) 4. top : Access next element (public member function ) 5. push : Insert element (public member function ) 6. pop : Remove top element (public member function ) Put function definitions outside the definition of the class (i.e. inline functions are not allowed).
Using C++ make a set of function templates that have these features: This function must return a value. A function template with 1 template parameter, T. And, any other parameters you want. A function template with 2 template parameters, T1 and T2. And, any other parameters you want. Using your own creativity, make a set of class templates that have these features: For this class template, put everything in one place--do not declare the member functions and have separate definition of the member functions elsewhere. Keep them in one place. Include a private variable. Include a constructor that loads the private variable when constructed. Include a destructor that clears the private variable to zero. Include set and get functions to set and get the private variable. For this class template, use declarations for variables and functions, like you do in header file (which you may use if you want). Then, separately put the full function definitions for each class member function…

Hello, I am having trouble with this homework question for my c++ course. Implement a Rational Number class with the following specifications. Data members a) numerator and denominator Functions a) Constructors: 1) default constructor 2) single parameter constructor to create numerator/1 3) dual parameter constructor to create numerator/denominator 4) Use constructor delegation across all constructors. b) Accessors and Mutators for both data members. c) Static recursive GCD function using Euclid's algorithm. d) Static LCM function for two numbers. e) Reduce function simplify a rational number. This function modifies its calling object. f) Your program should work with the supplied driver program. Notes LCM (Least Common Multiple) This function returns the smallest multiple of a and b. Step 1: Multiply a and b to find a common multiple. Step 2: Divide the common multiple by the GCD of a and b. Step 3: Return the result of Step 2. Reduce: This function reduces a fraction to…
