Matrix Problem

Code this in C


Write a program that reads two matrices of integers. It then generates the sum, difference, and product
of the two matrices.


The sum of the two matrices of the same size is a matrix with elements that are the sums of the
corresponding elements of the two given matrices. Addition is not defined for matrices of different sizes.


If A and B are matrices of the same size, then we define subtraction as follows: A – B = A + (-B). Thus, to
subtract matrix B from matrix A, we simply subtract corresponding elements.


To multiply a matrix by another matrix we need to do the "dot product" of rows and columns. The "Dot
Product" is where we multiply matching members, then sum up:


(1, 2, 3) • (7, 9, 11) = 1×ばつかける7 +たす 2×ばつかける9 +たす 3×ばつかける11 = 58


We match the 1st members (1 and 7), multiply them, likewise for the 2nd members (2 and 9) and the
3rd members (3 and 11), and finally sum them up.


Use the following definitions:
#define ROW 6
#define COL 6
void add(int matrixResult[][COL],int matrixA[][COL],int
matrixB[][COL],int row,int col);

//sum of matrixA and matrixB is assigned to matrixResult
void subtract(int matrixResult[][COL],int matrixA[][COL],int
matrixB[][COL],int row,int col);

//difference of matrixA and matrixB is assigned to matrixResult
void multiply(int matrixResult[][COL],int matrixA[][COL],int
matrixB[][COL],int row,int col);

//product of matrixA and matrixB is assigned to matrixResult


Note: You may initialize the two matrices during declaration. Make sure to test the functions inside main().
