FilternoneCan we overload all operators?Almost all operators can be overloaded except few. Following is the list of operators that cannot be overloaded. (dot)::?:sizeofWhy can’t. (dot),::,?: and sizeof be overloaded?See for answers from Stroustrup himself.Important points about operator overloading1) For operator overloading to work, at leas one of the operands must be a user defined class object.2) Assignment Operator: Compiler automatically creates a default assignment operator with every class.
The program asks the user to enter the matrices to be added. Then it calls the member functions of the class Matrix to get the matrices and add them by the overloaded '+' operator. Problem Solution: You can use the following algorithm 1. Define functions for getmatrix, displaymatrix, and overload the '+' operator. Take user input for matrices. Overload operators += and + Matrix c. Ask Question -3. Non-buggy copy semantics before doing any operator overloading, and right now, the copy semantics are faulty. – PaulMcKenzie Sep 22 '16 at 20:53. You are trying to add pointers. A, B and C are Pointers. To use Their operators, you need to dereference them.
The default assignment operator does assign all members of right side to the left side and works fine most of the cases (this behavior is same as copy constructor). See for more details.3) Conversion Operator: We can also write conversion operators that can be used to convert one type to another type.
Inside the operator., call the multiply function.Thanks for this advice, that that option won't really work. First, it's not intuitively obvious how I would go about it. How do you pass a copy of a structure to a function that exists within the structure? An interesting question, for which I wouldn't mind learning the answer. I suppose I could create a copy function within the class, and pass the copy to the multiply function - but that's adding complications.However, has has been suggested is a work around, rather than a solution. None of the examples of operator overload I have seen use this type of work around. So, I have to go back and assume that I am doing something wrong with the basic implementation of the function, the class, or both.Again, any help, or suggestions as to things I might read to find the answer, will be greatly appreciated.Tom.
Thats a problem with you multiply function then. Check the formula.Can you be more specific?The multiply function does produce the correct answer when invoked on its own. I've tested it with a number of different matrices, and it works every time.

So, I am fairly sure that the problem does not lie with the formula.But, even if it was a formula problem, why would the multiply function produce a different answer from the operator. function, when the body of the code for the two functions are essentially the same (this is especially true when you invoke multiply from within operator.).
