Write a C++ program to multiply two matrices a and b and print the result. Use two-dimensional arrays to represent the matrices.

Expert Solution

C++ Code:

#include <iostream>
using namespace std;

#define N 4

void multiply(int m1[][N],int m2[][N],int m3[][N])
{
   int i, j, k;
   for (i=0;i<N;i++) {
       for (j=0;j<N;j++) {
           m3[i][j]=0;
           for(k=0;k<N;k++)
               m3[i][j]+=m2[i][k]*m2[k][j];
       }
   }
}
int main()
{
   int i, j;
   int m3[N][N]; // To store result
   int m1[N][N]={{ 1,2,3,4 },{ 4,3,2,1 },{1,2,3,4},{4,3,2,1 } };

int m2[N][N]={ { 1,2,3,4 },{1,2,3,4},{1,2,3,4},{1,2,3,4} };
multiply(m1, m2, m3);

   cout << "Result after multiplication of matrix is \n";
   for (i=0;i<N;i++) {
       for (j=0;j<N;j++)
           cout<<m3[i][j]<< " ";
       cout << "\n";
   }
return 0;
}

*****In C++***** Exercise #3: Develop a program (name it AddMatrices) that adds two matrices. The matrices must of the same size. The program defines method Addition() that takes two two-dimensional arrays of integers and returns their addition as a two-dimensional array. The program main method defines two 3-by-3 arrays of type integer. The method prompts the user to initialize the arrays. Then it calls method Addition(). Finally, it prints out the array retuned by method Addition(). Document your code, and...
