tugas membuat program minggu ke 3

3)      membuat program class matrik

#include <iostream.h>

#include <conio.h>

class kali_matrik{

friend istream& operator>>(istream&,kali_matrik&);

friend ostream& operator<<(ostream&,kali_matrik&);

private:

int a[1][10];

int b[10][1];

int c;

int n;

};

istream& operator>>(istream& cin, kali_matrik& x){

cout<<"masukkan n untuk jumlah kolom(matrik a),jumlah baris(matrik b): ";

cin>>x.n;

cout<<"data matrik A :"<<endl;

for(int i=0;i<1;i++){

            cout<<"kolom "<<i<<" : ";

      for(int j=0;j<x.n;j++)

            cin>>x.a[i][j];

      }

cout<<"data matrik B :"<<endl;

for(int i=0;i<x.n;i++){

            cout<<"baris "<<i<<" : ";

      for(int j=0;j<1;j++)

            cin>>x.b[i][j];

      }

return cin;

}

ostream& operator<<(ostream& cout,kali_matrik& x){

cout<<"matrik A :"<<endl;

for(int i=0;i<1;i++){

                        cout<<"[";

            for(int j=0;j<x.n;j++)

                                     cout<<" "<<x.a[i][j];

             cout<<" ]"<<endl;

   }

cout<<"matrik B :"<<endl;

for(int i=0;i<x.n;i++){

                        cout<<"[";

            for(int j=0;j<1;j++)

                                     cout<<" "<<x.b[i][j];

             cout<<" ]"<<endl;

   }

int d=0;

for(int r=0;r<x.n;r++){

x.c=x.a[0][r]*x.b[r][0];

d+=x.c;

}

cout<<"hasil A*B = "<<"[ "<<d<<" ]";

return cout;

}

void main(){

kali_matrik a;

cin>>a;

cout<<a;
