MATRIK 4 January 2011

Contoh 1 :
#include <iostream>
using namespace std;
void main (){
for (int i=1;i<=4;i++){
for(int j=1;j<=3;j++)
cout<<i<<j<<" ";
cout<<endl;
}
system ("pause");
}

Contoh 2 :
#include <iostream>
using namespace std;
void main (){
int A[3][3];
for (int i=1; i<=2;i++)
...for (int j=1; j<=2; j++)
cin>>A[i][j];
//cetak matrix A
for (int i=1; i<=2; i++){
for (int j=1; j<=2; j++)
cout<<A[i][j];
cout<<endl;
}
system ("pause");
}

Test ===
#include <iostream>
#include <iomanip>
using namespace std;
void main (){
... int m, n;
int A[2][2];
cout<<"Masukkan jumlah baris : ";cin>>m;
cout<<"Masukkan jumlah kolom : ";cin>>n;

for (int i=1; i<=m;i++)
for (int j=1; j<=n;j++){
cout<<"A("<<i<<","<<j<<")";cin>>A[i][j];
}
//cetak matrik A
cout<< " Isi Matrik A =\n";
for (int i=1;i<=m;i++){
for (int j=1;j<=n;j++)
cout<<setw(5)<<A[i][j];
cout<<endl;
}
//perkalian Matrik A dengan sebuah konstanta k
int k,B;
cout<<"Masukkan Nilai Konstanta : ";cin>>k;
for (int i=1;i<=m;i++)
for (int j=1;j<=n;j++)
B[i][j]=k*A[i][j];
system ("pause");
}

SEMOGA BERMANFAAT
