Question

C++

Write a program to calculate the sum of two matrices that are stored inside two-dimensional arrays. Your program should include three functions: one for getting input data, one for calculating the sum of matrices, and one for printing the result.

a) Function inputMatrix: This Function prompts the user to enter the data and stores data inside two-dimensional array.

b) Function addMatrices: This function calculatesthe sum result of two matrices.

c) Function printMatrix: This function prints the matrix to screen.

You need to use "#define SIZE x" directive to set the constant for the size of arrays to x (arbitrary integeger value, dont make it too big). To make things easier, you can set the number of rows equal to the number of columns.

It is recommended to write the functions with the following signatures:

void inputMatrix(int matrix[SIZE][SIZE]);

void addMAtrices (int matrix1[SIZE][SIZE]), int matrix2[SIZE][SIZE]), int sum[SIZE][SIZE]);

void printMatrix(int matrix[SIZE][SIZE]);
