1. Matrix Addition, Subtraction and Multiplication

[junaidkhan2013]

1) Program a C++ function that prints out a given 5 x 5 matrix (void printMtrx(double mA[][SIZE_N], int size_n)). Use extended complete code to show the boundary of matrix.

2) Program a C++ function that calculates the addition of two 5 x 5 matrices, and returns the result as 2-dimensional parameter.

3) Program a C++ function that calculates the subtraction of two 5 x 5 matrices, and returns the result as 2-dimensional parameter.

4) Program a C++ function that calculates the multiplication of two 5 x 5 matrices, and returns the result as 2-dimensional parameter.

5) Calculate the addition, subtraction, multiplication of given matrices mA[][] and mB[][].

Use following main() function.
