//PennyBoki @ </dream.in.code>
#include <iostream.h>

int main()
{
     int A[3][3];
     int B[3][3];
     int C[3][3];
     int X[3][3][3];
     int i,j,m;
     
     
     cout<<"==========Enter matrix A==========n";
     for(i=0;i<3;i++)
     {     cout<<endl;
          for(j=0;j<3;j++)
          {     
               cout<<"A["<<i<<"]["<<j<<"]= ";
               cin>>A[i][j];
               C[i][j]=0;
          }
     }
     
     cout<<"n==========Enter matrix B==========n";
     for(i=0;i<3;i++)
     {     cout<<endl;
          for(j=0;j<3;j++)
          {     
               cout<<" B["<<i<<"]["<<j<<"]= ";
               cin>>B[i][j];
          }
     }
     
     
     for(i=0;i<3;i++)
     {     
          for(j=0;j<3;j++)
          {     
               for(m=0;m<3;m++)
               {
               X[i][j][m]=A[i][m]*B[m][j];
               C[i][j]+=X[i][j][m];
               }
          }
     }

     cout<<"n==========matrix C==========n";
     for(i=0;i<3;i++)
     {     cout<<endl;
          for(j=0;j<3;j++)
          {     
               cout<<" C["<<i<<"]["<<j<<"]= "<<C[i][j];
          
          }
     }
     cout<<endl<<endl;

return 0;
}
