Hi, I have made a class and have an overloaded ostream operator method in it... However it tells me: "overloaded 'operator<<' must be a binary operator (has 3 parameters)." Can someone tell me how to fix this? Thank you! I have included some of my code: class Element { private: list<Element*> _children; char* _tag; int _value; public: ostream& operator<<(ostream& out, const Element& E); // (preordered traversal) }

Greetings, I'm working on a class project for fractions and I'm stuck and cannot figure out where to go from here. We have a mandatory driver file we aren't supposed to change. See below for example output and the output I am actually getting. **Sample Output** Enter numerator; then denominator. 5 8 5/8 Enter numerator; then denominator. 4 10 4/10 Sum: 82/80 1.025 Product: 20/80 0.25 Enter numerator; then denominator. 6 0 infinity Driver file import java.util.Scanner; public class NathanialProg7 { public static void main(String[] args) { Scanner stdIn = new Scanner(System.in); Fraction c, d, x; // Fraction objects System.out.println("Enter …

I'm writing a program that works with two sets of numbers put into arrays. The program uses overloaded + and - operators. Array one = 2 7 4 2 9 7 Array two = 2 9 8 9 1 10 12 The output should be: For +, New Array = 2 7 4 9 10 8 1 12 For -, New Array = 7 4 2 7 My output is: Addition = 12 10 1 and Subtraction = 12 9 8 9 1 10 Here is the logic for the operators I used to write this code. The + operator: …

I'm currently making a DLL with a collection of code snippets that I find myself commonly using. I have made a search functin that checks if one string is inside of another string. I have also added a vector choice in the case that I want to search many strings. In the header: static DATAEDITING_API bool Contains(std::string target, std::string source); static DATAEDITING_API bool Contains(std::string target, std::vector<std::string> source); static DATAEDITING_API bool Contains(std::string target, std::string source, bool sensitive); static DATAEDITING_API bool Contains(std::string target, std::vector<std::string> source, bool sensitive); Now the problem is that the following code snippet always returns true. The Contains(std::string, std::string, …

Problem: The statement ++Chequebook1; should increment the member variable Balance of Chequebook1 by R100. Give three different implementations for the overloaded operator ++ to accomplish this: • using the member function Adjust() • implementing the overloaded operator ++ as a friend function • implementing the overloaded operator ++ as a member function ive been struggling with this one for days, i havent came up with a correct solution but heres my code: please help me :( //Question2 #include <iostream> #include <string> using namespace std; class Chequebook { public: //constructors Chequebook(); Chequebook(float amountBalance); //accessors/mutators void deposit(float amount); void withDraw(float amount); float …

Hi all, I have implemented overloaded function for operator new. In this function I have not allocated any memory still while exiting from program it is getting crashed. Code is as below: class A { public: int a; int b; A() { cout<<"Inside A::A()"<<endl; } void* operator new(size_t s) { cout<<s<<endl; cout<<"Inside A::new()"<<endl; } }; int main(int argc, char *argv[]) { A* a= new A; system("PAUSE"); return EXIT_SUCCESS; } Output of program is - 8 Inside A::new() Inside A::A() Crash
