How to multiply two matrices

#include <iostream>
using namespace std;
#define size 3      // number of rows  and column
void matixMultiplicaion(int MatrixA[][size], int MatrixB[][size]) {
    int result[size][size];  // declare result matrix 3 X 3
    for (int i = 0; i < size; i++) { // handle rows
        for (int j = 0; j < size; j++) { // handle column
            result[i][j] = 0; // assign default value
            for (int k = 0; k < size; k++) { // compute dot product of matrix
                result[i][j] += MatrixA[i][k] * MatrixB[k][j];
            }
            cout << result[i][j] << "  "; // print the resultan matrix 
        }
        cout << endl;
    }

       column size are same so we do not need to check
       the row and column are equal or not
