Perkalian Matriks Pada C++

Berikut adalah contoh untuk melakukan perkalian matriks pada C++ : 

#include <iostream.h>

#include <conio.h>

#include <iomanip.h>

void main()

{

            int MatA[3][3],MatB[3][3],X[3][3],a,b,c;

            clrscr();

            cout<<"Program perkalian dua buah matriks\n";

            cout<<"Silahkan input matriks A : \n";

            for(a=0; a<3; a++)

            {

                        for(b=0; b<3; b++)

                        {

                                    cout<<"Elemen ke "<<(a+1)<<","<<(b+1)<<" : ";

                                    cin>>MatA[a][b];

                        }

            }

            cout<<"\nMatrik A : \n";

            for(a=0; a<3; a++)

            {

                        for(b=0; b<3; b++)

                        {

                                    cout<<setw(4)<<MatA[a][b];

                        }

                        cout<<endl;

            }

            cout<<endl;

            cout<<"Silahkan input matrik B : \n";

            for(a=0; a<3; a++)

            {

                        for(b=0; b<3; b++)

                        {

                                    cout<<"Elemen ke "<<(a+1)<<","<<(b+1)<<" : ";

                                    cin>>MatB[a][b];

                        }

            }

            cout<<"\nMatrik B : \n";

            for(a=0; a<3; a++)

            {

                        for(b=0; b<3; b++)

                        {

                                    cout<<setw(4)<<MatB[a][b];

                        }

                        cout<<endl;

            }

            for(a=0; a<3; a++)

            {

                        for(b=0; b<3; b++)

                        {

                                    X[a][b]=0;

                                    for (c=0; c<3; c++)

                                    {

                                                X[a][b] += MatA[a][c] * MatB[c][b];

                                    }

                        }

            }

            cout<<"\nHasil perkaliannya adalah : \n";

            for(a=0; a<3; a++)

            {

                        for(b=0; b<3; b++)

                        {

                                    cout<<setw(4)<<X[a][b];

                        }

                        cout<<endl;

            }

            cout<<endl;

            getch();

            cout<<"\nHasil perkaliannya adalah : \n";

            for(a=0; a<3; a++)

            {

                        for(b=0; b<3; b++)

                        {

                        }

                        cout<<endl;

            }

            cout<<endl;

            getch();

}

hasil outputnya akan menjadi seperti ini :
