Contoh Program C++ (Penjumlahan Matriks 3x3)

#include<iostream.h>
void main()
{
int a[4][4],b[4][4],c[4][4];
int saya,anda;


cout<<"masukan anggota matriks A = "<<endl;

for(saya=0; saya<=3; saya++)
{
for(anda=0; anda<=3; anda++)
{
cin>>a[saya][anda];
}
cout<<endl;
}
cout<<"---------"<<endl;
cout<<"Matriks A"<<endl;
cout<<"---------"<<endl;
for (saya=0; saya<=3; saya++)
{
for (anda=0; anda<=3; anda++)
{
cout<<a [saya][anda]<<"  ";
}
cout<<endl;
}
cout<<endl;
cout<<"Masukan Komponen Matriks B:"<<endl;
for (saya=0;saya<=3;saya++)
{
for (anda=0;anda<=3;anda++)
{
cin>> b [saya][anda];
}
cout<<endl;
}

cout<<"---------"<<endl;

cout<<endl;
}
cout<<endl;
cout<<"--------------------------------------"<<endl;
cout<<"Hasil Dari Penjumlahan Matriks A dan B"<<endl;
cout<<"--------------------------------------"<<endl;
for (saya=0; saya<=3; saya++)
