Once you have defined these you should be all set. And read a matrix from a stream (stdin/stdout)įriend std::ostream operator>(std::istream& str, Matrix& input) Input and output operations so you can print a matrix Allow people to set matrixes via assignment Create a matrix (of specified width/height with all data set to zero Online C++ Operator Overloading programs and examples with solutions, explanation and output for computer science and information technology students pursuing BE, BTech, MCA, MTech, MCS, MSc, BCA, BSc. You also need to define a couple of standard functions (or disable some standard functions). C++ program for the addition of two matrices (use operator overloading). Looking at these properties I would define the following. What are the action that can be performed on a matrix. What are the properties of a matrix? 1) Width You need to look at a matrix as an object (not a thing that holds three matrixes). If you want to define Matrix Operations in a class like way. Now imagine I did int c = a + b and my output said "The sum of 1 and 2 is 3".

Instead of writing an example by hand I'll refer you to eigen where they did all of this plus some other neat tricks. The only purpose that matrix3 should have is to do matrix operations. You should try to make each class only have a single purpose. What you did is combine a container (holding multiple objects) together with input/output and the actual functionality of matrix operations. To print a matrix we would simply do this: std::cout << c << '\n'. Since we are aiming to mimic ints, the way we want to add matrices is this: matrix3 a =. To add 2 ints you write something like this: int a = 1 As a rule of thumb you should aim to make your data types behave roughly like an int because screwing up the usage of an int is pretty hard. However, if you make it overly complicated people cannot use it effectively. Matrix3 is a user defined data type and C++ gives you a lot of freedom to make it the way you want. values, organized as an outer vector of rows However, I guess it would also be ok to have them as member function that only takes the second matrix as parameter.Ĭonsider the following class definition: #include
Also, the sum, diff and transpose functions could be external functions that take two matrices as parameters and return a resulting matrix. When you re-design your matrix class to contain a single matrix, you should possibly externalize your user input logic. What you have is something like a matrix manager, that contains multiple matrices in a single instance. The key point is, that each matrix should be a distinguished instance of your matrix class. In your case, you have two input matrices and possibly a result matrix for the operation that the user selects. In OOP, it is important to identify the scope of an object.

Partial Answer This does not cover all aspects of your code, so feel free to wait for other responses. I'm a noob (less than 2 months into C++) so please pardon any nooby mistakes. Can anybody help me rectify the error here.
MATRIX ADDITION USING OPERATOR OVERLOADING IN C CODE
The code I made was supposedly wrong as I hadn't used classes the way they have to be used. So I recently had a practical exam in which I was told to execute a function of a menu oriented matrix operation program using classes.
