cout << "Masukan Bilangan Kedua = ";
cin >> angka2;

cout << endl << "Hasil Operasi = " << endl;
cout << "Penjumlahan = " << angka1 + angka2 << endl;
cout << "Pengurangan = " << angka1 - angka2 << endl;
cout << "Perkalian = " << angka1 * angka2 << endl;
cout << "Pembagian = " << angka1 / angka2 << endl;
cout << "Modulus = " << angka1 % angka2 << endl;
}
else{
cout << "Nama Anda Salah";
