[Solved] Please solve these errors. I’m using dev++ compiler [closed]

The first error is a typo you wrote pememory. The second error appears because you didn’t code any transformation between Float and ptrFloat. You should add a copy constructor to Float: Float(const Float& a) : Float(*a.fmem_top) {} And then a conversion constructor to ptrFloat: ptrFloat(Float a) : Float(a) { pmem_top=pmemory; *pmem_top=abc; pmem_top++; } PS: your … Read more

[Solved] What is the difference between overloading the assignment operator and any other operator?

Here are two differences: An overloaded assignment operator must be a member of the class being assigned to; it cannot be declared as a free function. Copy and move assignment operators will be implicitly declared for your class if you do not declare them yourself (subject to certain restrictions). solved What is the difference between … Read more

[Solved] What is the difference between overloading the assignment operator and any other operator?

Introduction The assignment operator is a special operator in C++ that is used to assign a value to a variable. It is different from other operators in that it can be overloaded, meaning that it can be given a new meaning or behavior. Overloading the assignment operator allows for more flexibility when assigning values to … Read more

[Solved] Template overloaded = operator works in one class and fails to compile in another? [closed]

You declare a class template PointIndices, but misspell it in the function definition: template<typename T> PointIndicess<T>& PointIndices<T>::operator=(const PointIndicess<T>& point) // ^ extra “s” here ^ and here solved Template overloaded = operator works in one class and fails to compile in another?

[Solved] generic number in c++

Possible through slightly different means. See example: #include <iostream> class X { public: X(int val) : value(val) { } // this is the important part template<class TYPE> X & operator+(TYPE input) { value += input; // just demonstrating with a simple int // a real bignum will be significantly more complex // and you may … Read more

[Solved] I want to overload “=” operator but it gives me error [closed]

An assignment operator with signature Fraction operator=(const Fraction &newfraction) has to be a member function. A friend function is not a member. So the numbers of parameters don’t match the 2 needed for assignment. Remove the friend and make sure it is declared as a member function. struct Fraction { Fraction& operator=(const Fraction &newfraction) { … Read more

[Solved] When should I return pointer to object (not an object) from the operator function?

You got a bad example. Short answer: never(!) return a pointer from a binary function (operator). Return by value or a std::unique_ptr or std::shared_ptr. Note: The accepted answer in the link of the question changed afterward. 2 solved When should I return pointer to object (not an object) from the operator function?

[Solved] What does =+ mean in c++ [duplicate]

s2=+s1 Means merely nothing more than applying the unary operator+() to the rvalue provided with the operator=()‘s parameter. That boils down to the same statement as s2 = (+s1); There’s no combined operator like operator+=() for that. That would have no effect at all, unless these operator functions are overloaded for specific (non primitive) types. … Read more

[Solved] input class object into array of objects [closed]

You don’t need new there, because you have an array of actorData and not actorData pointers, and the error is saying that it can’t convert actorData pointer to actorData. So replace this line: actorOrder[index] = new actorData(iNewOrder, sNewActor); with this: actorOrder[index] = actorData(iNewOrder, sNewActor); 0 solved input class object into array of objects [closed]
