Matrix Multiplication Program Using Arrays

Attached are the requirements for the program.

You are going to write a program to multiply two matrices.
The matrices are stored in a two-dimensional array:
int[][] matrixA
int[][] matrixB

Here is the way to declare a two-dimensional array:
int testArray[3][4] = {{1,2,3,4},{2,3,4,1},{5,4,3,0}}; // three rows, four columns
after declaration, testArray will be like:
1 2 3 4
2 3 4 1
5 4 3 0

This link may help you recall how to multiply two matrices
Your program should be like this:

this program multilies two matrices
#include <iostream>
/* include other libs */

using namespace std;

int main()
/* step1: declare three arrays here:
matrixA (3*4), 3 rows, 4 columns
matrixB (4*3),
and result (3*3)

/* step2: compute the result */

/* step3: output the result */

The values of matrices in your program can be hard-coded and any numbers you like(including the numbers of columns/rows and the values of matrices), which means you do not have to ask user to input those numbers. Of course you can do this if you would like to.

Dear friend,

As I could understand you are looking for a simple C++ function which allows you to multiply two matrices.
I would suggest you to write a template function which can work for other basic data types(like float, double and etc.)
However, I try to explain my function as ...

Solution Summary

A C++ function to multiply arrays is given.
